Motor Neuron Disease (MND)

Note4Students

From UPSC perspective, the following things are important :

Prelims level: MND and its causes; NIMHANS.

Why in the News?

The annual conference on Motor Neuron Disease (MND) ‘Awareness, Care and Management’ was held at NIMHANS.

What is Motor Neuron Disease (MND)?

  • MND is a condition that affects the nerves in the brain and spinal cord, which are responsible for controlling your muscles.
  • Over time, these nerves (called motor neurons) stop working properly, leading to muscle weakness and wasting away.

Types of MND:

  1. Amyotrophic Lateral Sclerosis (ALS): The most common type. It affects both upper and lower motor neurons, leading to weakness in various body parts.
  2. Progressive Bulbar Palsy (PBP): Affects the nerves in the brainstem, leading to problems with speaking and swallowing.
  3. Progressive Muscular Atrophy (PMA): Affects only the lower motor neurons, causing muscle weakness and wasting.
  4. Primary Lateral Sclerosis (PLS): Affects only the upper motor neurons, causing stiffness and movement difficulties.

Causes of MND:

  • Genetic Factors: In some families, MND can be inherited due to specific gene mutations.
  • Environmental Factors: Exposure to certain toxins, viruses, or physical injuries might contribute, but this is less clear.
  • Age and Gender: It usually affects people between the ages of 50 and 70 and is slightly more common in men.

Symptoms:

  • Muscle Weakness: Starts in one part of the body, like an arm or leg, and gradually spreads.
  • Muscle Cramps and Twitching: Small, involuntary muscle movements.
  • Difficulty Speaking and Swallowing: Due to weakness in the muscles used for these functions.
  • Breathing Problems: In advanced stages, muscles that control breathing can be affected.
  • Emotional Changes: Some people might experience changes in behavior or thinking.

Diagnosis:

  • Clinical Examination: A doctor examines your symptoms and medical history.
  • Electromyography (EMG): Tests the electrical activity of your muscles.
  • Nerve Conduction Studies (NCS): Checks how well your nerves send signals.
  • MRI: Scans to rule out other conditions.
  • Genetic Testing: To check for inherited forms of MND.

Treatment:

There is no cure for MND, but treatments can help manage symptoms and improve quality of life.

  1. Medications:
    • Riluzole: Can slow down the progression of ALS.
    • Edaravone: Another drug that may slow down the decline in daily activities.
    • Symptomatic Treatments: For muscle cramps, excess saliva, and emotional symptoms.
  2. Therapies:
    • Physical Therapy: Helps maintain muscle strength and mobility.
    • Occupational Therapy: Aids in performing daily activities.
    • Speech Therapy: Assists with speech and swallowing difficulties.
    • Respiratory Therapy: Supports breathing issues.

‘Cold Lava’ Rivers flow in Philippines after Mount Canlaon eruption

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Mount Canlaon, Cold Lava Mudflows

Why in the News?

  • After Mount Canlaon erupted in the Philippines, cold lava started flowing through streets and rivers.
    • It was followed by ashfall, and dangers like floods and mudflows downstream.

What is Cold Lava?

  • Cold lava, also known as “lahar,” is a mixture of water and rock fragments that flows rapidly down the slopes of a volcano, often triggered by heavy rainfall or volcanic eruptions.
  • The mixture forms a concrete-like substance that destroys everything in its path.
  • This can also include smooth, glassy textures or rough and jagged textures.

Another example of cold Lava in the world

  • Mount Merapi, Indonesia (2023): An eruption of Mount Merapi resulted in the deaths of at least 23 climbers and spewed ash up to 3,000 meters into the air, covering towns and villages

How harmful is Cold Lava?

  • Rain can carry cold lava down the slopes of a volcano during an eruption and into the path of nearby towns or villages.
  • According to the United States Geological Survey, cold lava has the power to crush and bury things in its path.
  • It also moves quickly like wet concrete and is considered more destructive than hot lava.

About Mount Canlaon

  • Mount Canlaon, located in the Philippines, is an active stratovolcano known for its frequent eruptions and volcanic activity.
  • It is situated on the island of Negros in the Visayas region of the Philippines.
  • It is part of the Pacific Ring of Fire, known for its high volcanic activity.
  • It poses hazards such as ash fall, lava flows, pyroclastic flows, and lahars (mudflows) that can endanger nearby communities and agriculture.

What is happening in the French territory of New Caledonia?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Mapping of New Caledonia

Why in the News?

New Caledonia, France’s Pacific island territory, is under a state of emergency due to deadly riots.

About New Caledonia 

  • New Caledonia is a French overseas territory in the Pacific.
  • It enjoys a large degree of autonomy but depends heavily on France for matters like defence and education.
  • It includes the island of New Caledonia where the capital, Noumea, is located, the Loyalty Islands; the Belep Islands; and the Ile des Pins.
  • New Caledonia’s lagoons were designated a UNESCO World Heritage site in 2008.

The Crisis: A Quick Recap

  • New Law: The French government passed a law that has upset people in New Caledonia.
  • Vote Reforms: Now, French citizens who lived on the island for 10 years or more can vote. The government says it’s fairer this way.
  • Resistance from Indigenous people: The locals, especially the Kanak community, feel this gives too much power to French settlers and stops them from gaining independence.

How did France occupy this territory? 

  • Exploration: British explorer James Cook named the island New Caledonia in 1774 after the Latin name for Scotland.
  • French Annexation: France annexed it in 1853 and New Caledonia became a French overseas territory in 1946.
  • Fewer Locals: France brought in lots of French people. Now, the original Kanak people are only 40% of the population, while others, like the Caldoches and newer French arrivals, make up the rest.

Why are the people protesting?

  • There were similar fights in the 1990s, leading to promises of more power for locals.
  • In 2018, 2020, and 2021, they voted on whether to be independent from France. But many boycotted the last vote, saying it wasn’t fair because of the pandemic.

Why is it significant for France?

  • France sees New Caledonia as important for keeping power in the region.
  • It wants to stay strong in the Pacific to stand up to other big powers, like China.

KAZA Summit 2024: Delegates renew calls to leave CITES

Note4Students

From UPSC perspective, the following things are important :

Prelims level: About CITES;

Mains level: The Kaza Summit and its objectives;

Why in the news?

At the KAZA 2024 Summit in Livingstone, Zambia, delegates reiterated the urge for member states to withdraw from CITES because they seek approval to trade their plentiful ivory and wildlife items.

About the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES):

  • It is an international agreement adopted in 1973 (entered into force in 1975) between governments.
  • Aim: To ensure that international trade in wild animals and plants does not threaten their survival.
  • Headquarters: Geneva, Switzerland.
  • Although CITES is legally binding on the Parties – in other words, they have to implement the Convention–it does not take the place of national laws.
  • Representatives of CITES nations meet every two to three years at a Conference of the Parties (COP) to review progress and adjust the lists of protected species, which are grouped into three categories with different levels of protection:
    • Appendix I: Includes the world’s most endangered plants and animals, such as tigers and gorillas. International commercial trade in these species, or even parts of them, is completely banned, except in rare cases such as scientific research.
    • Appendix II: Contains species like corals that are not yet threatened with extinction, but which could become threatened if unlimited trade were allowed. Also included are “look-alike” species that closely resemble those already on the list for conservation reasons. Plants and animals in this category can be traded internationally, but there are strict rules.
    • Appendix III: Species whose trade is only regulated within a specific country can be placed on Appendix III if that country requires cooperation from other nations to help prevent exploitation.

What is Kavango-Zambezi Trans-Frontier Conservation Area (KAZA-TFCA)?

  • The Kavango-Zambezi Trans-Frontier Conservation Area (KAZA-TFCA) spans 520,000 square kilometers. It covers parts of five southern African nations. These nations are Angola, Botswana, Namibia, Zambia, and Zimbabwe.
  • The area is centered around the Okavango and Zambezi river basins. The combined elephant population in these nations represents over two-thirds of Africa’s total, estimated at around 450,000.
  • Botswana has the largest elephant population within the region, with 132,000 elephants. Zimbabwe follows with 100,000 elephants.

Key Objectives of KAZA 2024 Summit :

  • Conservation: Promote the sustainable management and conservation of wildlife across the five member states: Angola, Botswana, Namibia, Zambia, and Zimbabwe.
  • Economic Benefit: To explore ways to monetize abundant wildlife resources, particularly elephants, to fund conservation efforts and benefit local economies.

Dominant Issues:

  • At the 19th meeting of the CITES conference in Panama in 2022, KAZA states and five other southern African countries advocated for opening up trade in ivory and elephant products.
  • Southern African countries, including those in the KAZA region, argue that their large elephant populations contribute to habitat loss and human-wildlife conflict.
  • Despite repeated requests, CITES delegates rejected the proposal, leading to frustration among African countries.
  • Ten countries, including KAZA states and others like Eswatini, Lesotho, Mozambique, South Africa, and Tanzania, declared a dispute with CITES. They criticized CITES for straying from its founding principles and adopting ideologies over science-based conservation strategies.

Way forward:

  • Lobbying for Change: Advocacy for a more equitable and science-based approach to wildlife trade regulations within international frameworks like CITES.
  • Regional Cooperation: Enhance collaboration among member states to develop joint conservation strategies and share best practices for managing human-wildlife conflicts.
  • Diversification of Revenue Streams: Explore alternative sources of funding for conservation efforts, such as ecotourism, carbon credits, and sustainable agriculture.

An overview of Sudan’s civil war 

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Bordering countries of Sudan;

Mains level: Important issues in the Global world;

Why in the News? 

The inability of successive governments to articulate a shared vision has resulted in the unfair distribution of wealth and resources in Sudan.

ANKARA, TURKIYE – NOVEMBER 3: An infographic titled ”Sudanese civil war intensifies in the western cities” is created in Ankara, Turkiye on November 3, 2023. Since mid-April, the intensity of the conflicts between the army and the Rapid Support Forces (RSF) in Sudan, which have resulted in nearly 10,000 casualties, shifted from the capital Khartoum and its surroundings to the western cities. (Photo by Yasin Demirci/Anadolu via Getty Images)

Historical background  of Conflict: 

  • In 1956: The government that came to power in 1956 emphasized an Arab and Islamic identity based on Mahdist principles. It was not representative of diverse communities and demanded compliance, leading to widespread resistance.
  • In 1989: In 1989, a new government seized control under the National Islamic Front, an alliance between army officers and the Muslim Brotherhood. Omar al-Bashir came to power, supported by Islamist leader Hassan al-Turabi, aiming to establish an Islamic state.
  • In 1991: The government set up an internal security apparatus, arresting and torturing dissenters. It introduced a new penal code in 1991 to impose an Islamization agenda.
  • In 2003: The al-Bashir (in 2003) regime enlisted Janjaweed militias to quell an insurgency in Darfur. These militias were later designated as the Rapid Support Forces in 2013.
  • In 2018-19: After protests in 2018 and al-Bashir’s removal in 2019, a transitional military government was established. Despite challenges and a failed coup attempt, a power-sharing agreement was reached, but another coup led by Abdel Fattah al-Burhan derailed the democratic transition.

Causes of the present conflict in Sudan:

  • Deep-rooted Crisis in Governance: The conflict reflects a longstanding crisis within Sudan’s governing structure since gaining independence in 1956, characterized by power struggles and frequent coups.
  • Identity Crisis and Rebellion: Sudan has experienced numerous rebellions fueled by an identity crisis, with marginalized populations seeking autonomy and fair representation within the state.
  • Ethnic and Regional Disparities: Sudan comprises of 19 major ethnic groups and about 597 ethnic sub-groups. Since independence, the Sudanese have experienced 35 coups and attempted coups, more than any other African country.
  • Religious and Political Ideologies: Shifts in government ideologies, such as the establishment of an Islamic state in 1989, have exacerbated tensions and led to further marginalization of certain groups.
  • Role of Militias: The emergence of paramilitary forces, such as the Rapid Support Forces, has complicated the conflict dynamics, with militias vying for power and control over resources.
  • Other country’s involvement: External influences, including support from foreign entities like Russia, have played a role in shaping the conflict landscape, particularly in resource-rich regions like Darfur.
  • Economic Interests: Economic factors, such as control over lucrative industries like gold mining, have contributed to the entrenchment of certain groups in power and fueled conflict dynamics.

Way Forward:

  • Establish a Civilian-Led Government: Sudan needs to prioritize the establishment of a transparent, civilian-led government that represents the diverse Sudanese populace. This government should ensure inclusivity and participation in decision-making processes.
  • Disarm and Demobilize Militias: Urgent action is needed to disarm and demobilize militias like the Rapid Support Forces. This will prevent militia dominance over the state and reduce the risk of armed confrontations and conflicts.
  • International Support for Reconstruction: Sudan requires collaborative efforts from the international community to aid in post-conflict reconstruction. This support can include financial assistance, capacity-building programs, and technical expertise to rebuild infrastructure, institutions, and communities affected by conflict.

H5N1 Bird Flu: Details

  • H5N1 originated from a virus outbreak on a goose farm in China in 1996 and has since evolved into a highly pathogenic strain.
  • The virus quickly spread from Europe to Africa, Asia, North America, and South America, and most recently, it reached mainland Antarctica.
  • H5N1 is a subtype of the influenza A virus that causes severe respiratory disease in birds, known as avian influenza or “bird flu”.
  • Influenza A viruses are classified by subtypes based on the properties of their surface proteins, with H5N1 being one subtype.

How widespread is it?

  • The virus has affected birds in over 80 countries, resulting in mass culling of poultry and wild birds.
  • Furthermore, it has now begun infecting mammals, including seals, sea lions, and marine mammals.
  • While humans rarely contract bird flu, those at risk are typically individuals who have extensive contact with infected birds at poultry farms.
  • Bird flu first broke out in Maharashtra in 2006.
  • The H5N1 virus led to the culling of millions of poultry so as to contain the virus. But it has resurfaced from time to time.

[PREMIUM] Travelling Central Asia

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Key locations mentioned in the news card

Mains level: NA

Why in the news?

The Central Asia region is in the spotlight since it is facing challenges with political instability, ethnic tensions, and the threat of extremism, especially after the withdrawal of US troops from Afghanistan.

About Central Asia

  • Central Asia, often referred to as the heart of Asia, is a vast and diverse region located at the crossroads of Europe and Asia.
  • It encompasses the area between the Caspian Sea in the west and China in the east, and from Russia in the north to Afghanistan and Iran in the south.
  • Central Asia is comprised of five main countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.
  • This region has a rich history, serving as the historical crossroads of the Silk Road, which facilitated trade and cultural exchange between Europe and Asia for centuries.

Geographical Details:

  • Mountains:
  • Tian Shan: This mountain range stretches across Central Asia, forming a natural border between Kyrgyzstan and China. It is renowned for its majestic peaks, including Pobeda Peak, the highest point in Kyrgyzstan.
  • Pamir Mountains: Known as the “Roof of the World,” the Pamir Mountains are located in Tajikistan and extend into neighboring countries. They contain some of the world’s highest peaks, including Ismoil Somoni Peak (formerly known as Peak Communism) and Kongur Tagh.
  • Alay Mountains: Situated in southern Kyrgyzstan, the Alay Mountains are a subrange of the Tian Shan. They are characterized by rugged terrain and deep valleys.
  • Turkestan Range: This mountain range runs through southern Kazakhstan and Uzbekistan, forming part of the border between the two countries.
  • Water Bodies:
  • Amu Darya: Also known as the Oxus River, the Amu Darya is one of the major rivers in Central Asia. It originates in the Pamir Mountains and flows through Tajikistan, Uzbekistan, and Turkmenistan before emptying into the Aral Sea (though much of its water is diverted for irrigation).
  • Syr Darya: Another important river in Central Asia, the Syr Darya, originates in the Tian Shan Mountains. It flows through Kyrgyzstan, Tajikistan, Uzbekistan, and Kazakhstan, eventually joining the Amu Darya in the Aral Sea basin.
  • Aral Sea: Once the fourth-largest lake in the world, the Aral Sea has shrunk dramatically due to diversion of its tributary rivers for irrigation purposes. Its decline has had severe ecological and economic consequences for the region.
  • Issyk-Kul: Located in eastern Kyrgyzstan, Issyk-Kul is one of the largest alpine lakes in the world. It is surrounded by snow-capped mountains and is a popular tourist destination.
  • Deserts:
  • Karakum Desert: Covering much of Turkmenistan, the Karakum Desert is characterized by vast expanses of sand dunes and sparse vegetation. It is home to the Darvaza Gas Crater, also known as the “Door to Hell.”
  • Kyzylkum Desert: Situated primarily in Uzbekistan, with parts extending into Kazakhstan, the Kyzylkum Desert is known for its red sands and arid climate. It is sparsely populated, with nomadic herders and wildlife such as gazelles and wild boars.
  • Mineral Resources:
  • Oil and Gas: The Caspian Sea region, in particular, is known for its oil and gas deposits, with countries like Kazakhstan and Turkmenistan actively involved in their exploration and extraction. The discovery of large oil fields, such as the Tengiz Field in Kazakhstan and the Galkynysh Field in Turkmenistan, has attracted international investment and contributed to economic growth in the region.
  • Uranium: Kazakhstan is one of the world’s leading producers of uranium, with significant deposits located in the south of the country. Other Central Asian countries, such as Uzbekistan and Tajikistan, also have uranium reserves, although they are less developed than those in Kazakhstan.
  • Precious Metals: Kyrgyzstan has a long history of gold mining, with several large-scale mines operating in the country. Uzbekistan is also a significant producer of gold, with the Muruntau Gold Mine being one of the largest in the world.
  • Copper, Aluminum, and Iron: These resources are primarily found in mountainous regions, such as the Tian Shan and Pamir Mountains. Countries like Uzbekistan and Tajikistan have large deposits of copper ore, which are mined for domestic use and export. Additionally, Kazakhstan is a major producer of aluminum, with significant reserves of bauxite, the primary source of aluminum.
  • Climate
  • Central Asia experiences a continental climate, with hot summers and cold winters.
  • However, the climate varies significantly depending on altitude and proximity to mountain ranges.
  • In general, the region is characterized by low precipitation and high evaporation rates, leading to arid and semi-arid conditions in many areas.
  • The mountains influence local climates, with cooler temperatures and higher precipitation levels in upland areas.

Icequakes on Ross Ice Shelf

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Ross Ice Shelf, Whillans Ice Stream

Mains level: NA

Why in the news?

  • Scientists found out that the huge Ross Ice Shelf, almost as big as France, moves forward a few centimetres daily.
  • This happens because of the Whillans Ice Stream, a fast-moving river of ice that sometimes gets stuck and then suddenly moves forward.

About Ross Ice Shelf

  • Ross Ice Shelf is the largest ice shelf of Antarctica roughly the size of France.
  • It was discovered by Sir James Clark Ross on 28 January 1841.
  • The shelf spans an area of roughly 500,809 square kilometers, about the size of France or the Yukon Territory in Canada.
  • It is several hundred meters thick. In the shelf’s southern reaches, nearest the True South Pole, the ice can be as thick as 750m.
  • The nearly vertical ice front to the open sea is more than 600 km long, and between 15 and 50 meters high above the water surface. However, 90% of the floating ice is below the water surface.
  • It is fed primarily by giant glaciers, or ice streams, that transport ice down to it from the high polar ice sheet of East and West Antarctica.
  • Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand.
  • It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea.

Spotlight: Icequakes on Ross Ice Shelf

  • Influence of Ice Stream: Most glaciers move slowly, but the Whillans Ice Stream stops and starts suddenly. This might happen because there isn’t enough water below to help it move smoothly.
  • Sudden Movements: These sudden movements, like tiny earthquakes, push against the Ross Ice Shelf.
  • Threat to Stability: Even though these daily shifts aren’t caused by humans, they could make the Ross Ice Shelf weaker over time. Ice shelves slow down the flow of ice into the ocean.
  • Retreat of Glacier: If the Ross Ice Shelf gets weaker or breaks, it could speed up melting and raise sea levels.

Mount Etna’s Volcanic Vortex Rings: A Rare Natural Phenomenon

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Mt. Etna, Sisily, Stratovolcano, Volcanism, Vortex Rings

Mains level: NA

Mt. Etna

Why in the news?

Mount Etna, located on the east coast of Sicily in Italy recently gained attention for emitting circular rings of vapor from its summit, known as volcanic vortex rings.

About Mount Etna

  • Mount Etna is located on the east coast of Sicily, Italy.
  • It is an active stratovolcano, characterized by its conical shape formed by layers of hardened lava, ash, and volcanic rocks.
  • It is Europe’s tallest active volcano, standing at approximately 3,329 meters (10,922 feet) above sea level.
  • It is one of the most active volcanoes in the world and has been erupting for thousands of years, with the first recorded eruption dating back to around 1500 BCE.
  • Mount Etna and its surrounding area have been designated as a UNESCO World Heritage Site since 2013, recognizing its geological significance and natural beauty.
  • It boasts five craters responsible for eruptions, alongside numerous vents along its slopes.

What are Volcanic Vortex Rings?

  • Volcanic vortex rings are a rare phenomenon observed when gas, primarily water vapor, is rapidly released through a vent in the volcano’s crater, forming circular rings of smoke above the mountain.
  • This phenomenon, similar to smoke rings blown by cigarette smokers, occurs when gas is expelled through a nearly perfect circular vent in the crater.
  • These rings can rise in the air for up to 10 minutes but may disintegrate quickly under windy conditions.

Volcanism in Italy

  • The volcanism of Italy is due chiefly to the presence, a short distance to the south, of the boundary between the Eurasian Plate and the African Plate.
  • Italy is a volcanically active country, containing the only active volcanoes in mainland Europe (while volcanic islands are also present in Greece, in the volcanic arc of the southern Aegean).
  • The lava erupted by Italy’s volcanoes is thought to result from the subduction and melting of one plate below another.
  • Other active volcanoes include Mt. Stromboli and Vesuvius.

Historical and Recent Observations

  • Etna produces more vapor rings than any other volcano on Earth, making it a hotspot for studying this phenomenon.
  • The occurrence of volcanic vortex rings was first documented in 1724 at Mount Etna and Vesuvius in Italy, and has since been observed at various volcanoes worldwide.
  • Recent observations of this phenomenon have been reported at volcanoes in Alaska, Ecuador, Guatemala, Iceland, Italy, Japan, Vanuatu, New Zealand, and Nicaragua.

Recent Volcanic Eruptions in News:

Many of the world’s most active volcanoes are concentrated in the Pacific Ring of Fire, encompassing regions like New Zealand, Southeast Asia, Japan, and the western coast of the Americas. This volatile area also experiences about 90% of all earthquakes globally.

  • Kilauea, Hawaii: The Kilauea volcano in Hawaii captivated the world with a nearly nonstop eruption that began in 1983 and continued for an astonishing 35 years until 2018. Remarkably, it rekindled in 2021, with the eruption still ongoing.
  • Dukono, Indonesia: Erupting since August 1933, Dukono volcano in Indonesia stands as a testament to long-term volcanic activity, defying the passage of time.
  • Santa Maria, Guatemala: The eruption of Santa Maria in Guatemala commenced in June 1922 and persists to this day, underscoring the enduring nature of certain volcanic phenomena.
  • Yasur, Vanuatu: Yasur in Vanuatu first erupted around 1270 and has maintained its volcanic activity, continuing as of June 9, 2023.

Understanding Volcanoes

  • Volcanoes are geological features characterized by openings or vents through which lava, tephra (small rocks), and steam erupt onto the Earth’s surface.
  • They result from both their own eruptions and the broader processes of tectonic plate movement.
  • Volcanic eruptions are essentially the result of magma, or molten rock, beneath the Earth’s surface rising, bubbling, and ultimately overflowing, much like boiling milk spilling out of a pot on a stove.
  • The magma seeks pathways to vents within the volcano, where it erupts and is expelled across the land and into the atmosphere, a phenomenon referred to as lava.

Appearance Formation Eruption Style Notable Examples
Cinder Cones Small, steep, conical Formed from basaltic magma with high gas content Often explosive eruptions with cinders/scoria Paricutin (Mexico), Sunset Crater (USA)
Composite/Stratovolcanoes Tall and symmetrical Result from alternating layers of lava, ash, etc. Both explosive and effusive eruptions Mount St. Helens (USA), Mount Fuji (Japan)
Shield Volcanoes Broad and gently sloping Primarily formed from basaltic magma Primarily non-explosive with extensive lava flows Mauna Loa, Mauna Kea (Hawaii)
Lava Domes Rounded dome-like shape Formed from slow extrusion of viscous magma Typically non-explosive but can be dangerous Novarupta Dome (Alaska), Mount St. Helens’ Lava Dome (USA)
