An 8.8 magnitude earthquake hit off Russia’s Kamchatka Peninsula, triggering 16-foot tsunamis that reached Hawaii and northern California in the US.

About Earthquakes:
- Overview: Sudden ground shaking caused by release of stored energy in Earth’s crust due to tectonic stress.
- Cause: Occurs when tectonic plates slip at fault lines where stress had built up due to friction.
- Seismic Waves: Energy travels as:
- Primary Waves (P-waves): Fastest, compressional.
- Secondary Waves (S-waves): Slower, shear motion.
- Key Terms:
- Focus (Hypocenter): Underground origin point.
- Epicenter: Surface point directly above the focus.
- Measurement:
- Magnitude: Energy released (Richter Scale, logarithmic).
- Intensity: Observed ground shaking (varies by location).
- Seismograph: Records seismic wave activity.
How Earthquakes Trigger Tsunamis?
- Underwater Epicenter: Must occur beneath oceans to displace water.
- Shallow Depth: Quakes at <70 km transfer energy more efficiently to water surface.
- Reverse Faulting: One tectonic plate pushes over another, vertically shifting the seafloor.
- Rapid Displacement: Sudden seafloor uplift/downthrust generates massive water waves.
- High Magnitude: Quakes >7.0 (especially >8.0) likely to trigger tsunamis.
About the Kamchatka Region:
- Overview: Russian Far East; borders the North Pacific Ocean.
- Tectonic Zone: Sits on the Kuril-Kamchatka Trench—Pacific Plate subducting under Okhotsk Plate at ~86 mm/year.

Iran’s Parliament has approved a motion to block the Strait of Hormuz, raising concerns worldwide.

About the Strait of Hormuz:
- Geographic Location: The Strait of Hormuz is a narrow waterway that connects the Persian Gulf to the Gulf of Oman and eventually to the Arabian Sea.
- Dimensions: It is about 167 km long and 33 km wide at its narrowest, making it one of the world’s most strategic maritime chokepoints.
- Bordering Countries: The strait lies between Iran (north) and Oman (south), with nearby cities such as Bandar Abbas, Khasab, and Dubai.
- Shipping Lanes: It contains designated lanes just 3 km wide in each direction to manage heavy oil tanker traffic.
- Key Islands: Important islands include Qeshm, Hormuz, and Hengam (controlled by Iran) and disputed ones like Abu Musa and the Tunbs, claimed by both Iran and the UAE.
- Naval Depth Advantage: Waters near the Musandam Peninsula reach depths over 650 feet, ideal for deep-draft oil tankers.
- Security Risks: Due to its narrowness, the strait is vulnerable to disruption from mining, military action, or cyber interference.
- Historical Tensions: It has witnessed frequent maritime tensions, especially during Iran–West conflicts but has never been fully blocked.
Its significance:
- Global Oil Flow: Over 20 million barrels of crude oil per day pass through the strait, accounting for 25% of seaborne oil trade and 20% of global consumption.
- Gas Exports: It is vital for LNG exports, especially from Qatar, reaching markets across the globe.

Mount Etna, Europe’s largest active volcano, has erupted sending ash, smoke, and rock fragments several kilometres into the sky.
Why do Volcanoes Erupt?
- Magma Formation: Deep within Earth, high temperature and pressure melt rocks into magma.
- Gas Expansion: Magma contains gases like water vapor, CO₂, and SO₂. As magma rises, the pressure drops, allowing these gases to form bubbles, increasing internal pressure.
- Crustal Weaknesses: At tectonic boundaries or mantle plumes, cracks and faults in Earth’s crust provide pathways for magma to escape.
- Eruption Mechanism:
- As pressure builds, magma is pushed upwards.
- If blocked, the gas expansion can explode through the crust, ejecting lava, ash, and gases.
- Signals: If magma flow is suddenly stopped by solid rock, it may create low-frequency seismic waves (pre-eruption tremors).
|

About Mount Etna:
- Location: Situated on the east coast of Sicily, Italy, near the city of Catania.

About the Heard and McDonald Islands
- The Heard and McDonald Islands are located in the Southern Ocean, approximately 4,100 km south-west of Perth, Australia, and 1,600 km to the north of the Antarctic coast.
- The islands are unincorporated external territories of Australia, meaning they are not part of any Australian state but are directly administered by the Australian government.
- The islands are home to seals, penguins, and albatrosses, and serve as crucial breeding grounds for these species.
- The islands have been designated as UNESCO World Heritage Sites due to their ecological significance, particularly their rich biodiversity.
- Heard Island:
- Heard Island spans an area of approximately 368 square kilometers.
- The island’s highest point is Mawson Peak, an active volcano standing 2,745 meters (9,006 feet) above sea level.
- Mawson Peak is one of the most active volcanoes in the southern hemisphere, with eruptions as recent as 2016.
- McDonald Islands:
- It is much smaller, covering only 2.5 square kilometers.
- Geological Nature: These islands are volcanic and part of the same volcanic chain as Heard Island.
- Climate
- Both islands experience an extremely cold subantarctic climate, with heavy winds, snow, and ice for much of the year.
- Temperatures rarely exceed 5°C (41°F) even in summer.
Strategic Significance
- The islands are strategically located between Australia and Antarctica, important for monitoring the Southern Ocean, vital for global biodiversity and climate studies.
- They play a key role in scientific research, particularly in volcanology, glaciology, and climate change, with Australia operating a research station on Heard Island.

Researchers have discovered a significant pause in coral reef growth in the Gulf of Eilat/Aqaba during the late Holocene period.
Key Highlights of the Study:
- The study identified a 4,400 – 1,000-year hiatus in coral growth, similar to events observed in Mexico, Brazil, and Australia.
- Scientists attribute this temporary halt to a sea-level drop caused by tectonic activity and cooling events, which exposed coral reefs and disrupted their development.
- Despite this, the reef recovered by recolonizing from deeper coral communities, showcasing its natural resilience.
