From UPSC perspective, the following things are important :
Prelims level: Gibraltar Strait, Tectonic Plate Boundaries, Subduction Zones
Mains level: Read the attached story
What is the news?
- Scientists in Portugal have uncovered a concerning revelation about the fate of the Atlantic Ocean, highlighting a potential ‘Ring of Fire’ (a Subduction Zone).
- Researchers caution that the Atlantic may be on the brink of closure due to subduction activity.
Why discuss this?
- Closure of Gibraltar Strait: Computer simulations project the subduction zone’s expansion over the next 20 million years, forming the ‘Ring of Fire’ in the Atlantic leading to the closure of Gibraltar Strait.
- Geological Parallel: This process mirrors the Pacific Ocean’s Ring of Fire, reshaping the ocean basin through gradual subduction of the ocean floor beneath continents.
|
About Gibraltar Strait
|
Details |
| Location |
- Connects the Atlantic Ocean to the Mediterranean Sea;
- Separating the southern tip of the Iberian Peninsula of Europe from the northern coast of Africa.
|
| Width |
Approximately 13 km (8.1 miles) at its narrowest point. |
| Depth |
Varies, with the deepest point reaching around 300 meters (984 feet). |
| Formation |
- Convergence point for the Eurasian Plate and the African Plate.
- Formed around 5.33 million years ago during the Messinian salinity crisis when the Atlantic Ocean breached the barrier separating it from the Mediterranean Sea, resulting in a catastrophic flood known as the Zanclean flood.
- The strait’s current shape and depth were further influenced by tectonic movements and erosional processes over geological time.
|
| Historical Significance |
Serves as a key maritime passage for trade and military purposes. |
| Disputes |
- Subject of contention between Spain and the United Kingdom;
- Gibraltar Overseas Territory under British control.
|
What are Subduction Zones?
- Subduction zones occur at convergent plate boundaries, where two tectonic plates move toward each other.
- This convergence is often between an oceanic plate and a continental plate or between two oceanic plates.
- Subduction Process:
- Collision of Tectonic Plates: When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate or another oceanic plate.
- Partial Melting: As the oceanic plate descends into the mantle, it generates intense heat and pressure, causing partial melting of the mantle material.
- Volcanic Activity: The molten material formed by the subduction process rises through the Earth’s crust, leading to volcanic eruptions at the surface.
- Formation of Volcanic Arcs: These eruptions often occur in chains known as volcanic arcs, which parallel the subduction zone. Ex. Andes in S. America; Cascade Range in North America.
Implications of this Activity
- Earthquakes: Subduction zone earthquakes can be particularly destructive and may trigger tsunamis due to the displacement of large volumes of water.
- Trench Formation: The surface expression of a subduction zone is often a deep oceanic trench, where the descending plate bends and plunges into the mantle.
- Mountain Building: Over time, the continuous subduction of oceanic crust can lead to the uplift and deformation of the overriding plate, resulting in the formation of mountain ranges adjacent to the subduction zone. These mountains may exhibit complex geological structures, including folds and faults.
- Recycling of Oceanic Crust: As oceanic plates are subducted, they are gradually consumed by the mantle, releasing minerals and elements that are eventually returned to the surface through volcanic activity.

From UPSC perspective, the following things are important :
Prelims level: Second Thomas Shoal
Mains level: NA
In the news
- Recently Philippines and China Coast Guard collided with each other near the Second Thomas Shoal of the Spratly Islands in South China Sea.
About Second Thomas Shoal
- It is located approximately 105 nautical miles (195 km) west of Palawan, Philippines.
- It lies within the Philippines’ EEZ (exclusive economic zone).
- The shoal is part of the Spratly Islands, which are subject to overlapping territorial claims by multiple countries, including China, the Philippines, Vietnam, Malaysia, and Taiwan.
- It is strategically significant due to its location in the South China Sea, a major maritime trade route rich in natural resources.
| Note: An Exclusive Economic Zone (EEZ) is an area of the ocean, generally extending 200 nautical miles (230 miles/370.15 km) beyond a nation’s territorial sea, within which a coastal nation has jurisdiction over both living and non-living resources. |
What is the South China Sea Dispute?
- It is a dispute over territory and sovereignty over ocean areas, and the Paracels and the Spratlys – two island chains claimed in whole or in part by a number of countries.
- China, Vietnam, the Philippines, Taiwan, Malaysia, and Brunei all have competing claims.
- Alongside the fully-fledged islands, there are dozens of rocky outcrops, atolls, sandbanks, and reefs, such as the Scarborough Shoal.
- China claims by far the largest portion of territory – an area defined by the “nine-dash line” which stretches hundreds of miles south and east from its most southerly province of Hainan.
- Beijing says its right to the area goes hundreds of centuries to when the Paracel and Spratly island chains were regarded as integral parts of the Chinese nation.
- It showed the two island groups falling entirely within its territory. Those claims are mirrored by Taiwan.
Spat over Chinese claims
- China has backed its expansive claims with island-building and naval patrols.
- The US says it does not take sides in territorial disputes but has sent military ships and planes near disputed islands, calling them “freedom of navigation” operations to ensure access to key shipping and air routes.
- Both sides have accused each other of “militarizing” the South China Sea.
- There are fears that the area is becoming a flashpoint, with potentially serious global consequences.

From UPSC perspective, the following things are important :
Prelims level: West Asia
Mains level: Read the attached story
Introduction
- What initially began as a localized conflict between Israel and Hamas has rapidly spiralled into a regional security crisis, casting a shadow of uncertainty and instability over West Asia.
- This evolving crisis involves a complex web of state and non-state actors, each with its own objectives and strategies, making it a highly volatile and unpredictable situation.
Escalation beyond Borders
As Israel launched its military campaign in Gaza in response to Hamas’s cross-border attacks, concerns grew that the conflict could spill over beyond the borders of Palestine. The involvement of various actors has further complicated the situation:
- Hezbollah’s Solidarity: Hezbollah, the Lebanese Shia group backed by Iran, fired rockets at Israeli forces in solidarity with the Palestinians. This action marked an extension of the conflict beyond the immediate theatre of operations.
- Exchange of Fire: Israel and Hezbollah engaged in multiple exchanges of fire, with both sides exercising restraint to prevent a full-scale war. Nevertheless, these incidents escalated regional tensions.
- Iran-Backed Militias: Iran, a key supporter of non-state actors in the region, provided backing to groups such as Hamas, the Islamic Jihad, Hezbollah, Houthis, and Shia militias in Iraq and Syria. This support has contributed to the widening of the crisis.
- Houthi Disruptions: In a bid to express solidarity with the Palestinians, Houthi rebels in Yemen began targeting commercial vessels in the Red Sea. Controlling significant portions of Yemen, including the Red Sea coast, the Houthis disrupted maritime traffic in a crucial international waterway.
Global Ramifications
The crisis in West Asia has not remained confined to the region; it has global implications:
- U.S. Airstrikes in Yemen: The United States, in support of Israel’s actions, conducted airstrikes in Yemen, directly involving itself in the regional conflict. These airstrikes added a new dimension to the crisis.
- Hashad al-Shabi’s Escalation: The Shia Mobilisation Forces of Iraq and Syria, backed by Iran, launched over a hundred attacks against U.S. troops stationed in these countries. These attacks were seen as retaliation against U.S. support for Israel.
- Spread of Instability: As instability spread across the region, extremist groups, including the Islamic State, sought to exploit the situation. Iraq and Syria, in particular, remained vulnerable to internal and external challenges.
- Cross-Border Retaliation: In response to Iran’s actions, Pakistan carried out airstrikes in Iranian territory, further escalating tensions in the region.
Key Players and Their Objectives
Understanding the crisis requires an examination of the key players and their objectives:
- Israel’s Aims: Israel’s primary objectives include dismantling Hamas and securing the release of hostages held by the group. Israel enjoys unwavering support from the United States in pursuing these goals.
- Iran’s Backing: Iran plays a central role as the primary supporter of various anti-Israel non-state actors in West Asia, offering support to groups such as Hamas, the Islamic Jihad, Hezbollah, Houthis, and Shia militias.
- U.S. Interests: The United States, with a significant military presence in the region, seeks to ensure Israel’s security, protect American troops and assets, and maintain the U.S.-led order in West Asia.
Implications for Regional Security
The crisis in West Asia has ushered in a period of heightened insecurity and instability:
- Widespread Security Crisis: Unlike previous conflicts that often involved nation-states or specific non-state actors, this crisis encompasses a broader range of powerful states and non-state actors, creating a highly volatile environment.
- Disruption of the Old Order: The crisis has exposed the fragility of the old U.S.-led order in the region. Iran-backed proxies directly target Israeli and American positions, while Iran flexes its military muscle through cross-border attacks.
Looking Ahead
As the crisis continues to unfold, several key factors warrant consideration:
- No Clear Resolution: With more than 100 days of conflict, Israel’s objectives in Gaza remain unfulfilled, and there is no apparent path to a resolution. The ongoing war fuels retaliatory attacks by Hezbollah and Houthis.
- Effectiveness of U.S. Airstrikes: U.S. airstrikes against various groups have not proven effective in deterring them from launching new attacks. The region remains volatile.
- Potential for Further Instability: The ongoing instability in West Asia creates opportunities for extremist groups, including the Islamic State, to exploit the situation. Iraq and Syria remain particularly susceptible to internal and external challenges.
- Changing U.S. Role: Historically, the United States played a dominant role in the region, but it now appears more as a disruptor than a guarantor of peace and stability. Restoring stability and ending the war present significant challenges.
- A Glimmer of Hope: Amid the ongoing crisis, a positive development is the maintenance of the Saudi-Iran détente and the Saudi-Houthi peace, providing a ray of hope amidst the turmoil.
Conclusion
- The escalating regional crisis in West Asia underscores the intricate interplay of state and non-state actors in a highly volatile environment.
- As the situation continues to evolve, its implications for regional stability and global security remain a subject of concern and vigilance.
