Ring of Fire

Nine people died and more than 1,000 were injured in Taiwan after the island was hit by its biggest earthquake in at least 25 years on Wednesday (April 4) morning.

What is the Ring of Fire?

  • The Ring of Fire is essentially a string of hundreds of volcanoes and earthquake sites that run along the Pacific Ocean.
  • It is a semicircle or horseshoe in shape and stretches nearly 40,250 kilometers.
  • The Ring of Fire traces the meeting points of numerous tectonic plates, including the Eurasian, North American, Juan de Fuca, Cocos, Caribbean, Nazca, Antarctic, Indian, Australian, Philippine, and other smaller plates, which all encircle the large Pacific Plate, according to a report by National Geographic.
  • It runs through 15 more countries including the USA, Indonesia, Mexico, Japan, Canada, Guatemala, Russia, Chile, Peru, and the Philippines.

Why is the Ring of Fire Vulnerable to Earthquakes?

  • The Ring of Fire witnesses so many earthquakes due to constant sliding past, colliding into or moving above or below each other of the tectonic plates.
  • As the edges of these plates are quite rough, they get stuck with one another while the rest of the plate keeps moving.
  • An earthquake occurs when the plate has moved far enough and the edges unstick on one of the faults.

Why are There so Many Volcanoes in the Ring of Fire?

  • The existence of volcanoes in the Ring of Fire is also due to the movement of tectonic plates.
  • Many of the volcanoes have been formed through a process known as subduction.
  • It takes place when two plates collide with each other and the heavier plate is shoved under each other, creating a deep trench.
  • “When a ‘downgoing’ oceanic plate [like the Pacific Plate] is shoved into a hotter mantle plate, it heats, volatile elements mix, and this produces the magma.
  • The magma then rises through the overlying plate and spurts out at the surface,” which leads to the formation of volcanoes, according to a report by DW.
  • Most of the subduction zones on the planet are located in the Ring of Fire and that’s why it hosts a large number of volcanoes.

Why is Taiwan so Exposed to Earthquakes?

  • Taiwan lies along the Pacific “Ring of Fire,” the line of seismic faults encircling the Pacific Ocean where most of the world’s earthquakes occur.
  • The area is particularly vulnerable to temblors due to the tension accumulated from the interactions of two tectonic plates, the Philippine Sea Plate and the Eurasian Plate, which may lead to sudden releases in the form of earthquakes.
  • The region’s mountainous landscape can magnify the ground shaking, leading to landslides.

Glacial Lake Outburst Floods

  • 04 Apr 2024

Why is it in the News?

Recently, the Uttarakhand government has constituted two teams of experts to evaluate the risk posed by five potentially hazardous glacial lakes in the region.

What is Glacial Lake Outburst Flood (GLOF)?

  • A GLOF denotes the sudden release of meltwater from a moraine or ice-dammed glacial lake, typically due to dam failure.
  • These events pose significant hazards, often resulting in catastrophic flooding downstream, leading to substantial loss of life and property.
  • GLOF can be triggered by several factors, including earthquakes, heavy rains, and avalanches.

Key Features of GLOFs:

    • Sudden water releases.
    • Rapid occurrences lasting hours to days.
    • Large downstream river discharges.

Threats Posed by GLOFs in the Himalayan Regions:

  • Climate Change Impact: Climate change-induced glacier melt accelerates the formation or expansion of glacial lakes, heightening the risk of GLOFs.
  • Vulnerability of Moraines and Dams: Glacial lakes situated behind unstable moraines or natural dams are prone to breaching, as evidenced by events like the Kedarnath floods in 2013.
  • Immediate Flood Risks: Abrupt water releases trigger massive floods, causing extensive damage to homes, and infrastructure, and triggering landslides and sedimentation.

Mitigation Strategies for GLOFs:

  • Risk Assessment and Zonation: Identify high-risk areas and implement necessary mitigation measures, including mapping and modeling, as outlined in the 'Guidelines for Preparation of Disaster Management Plans for Glacial Lake Outburst Floods (GLOF)'.
  • Early Warning Systems: Establish monitoring networks with sensors to detect changes in glacial lakes and provide timely warnings to vulnerable communities.
  • Utilization of Technology: Leverage remote sensing and GIS-based tools for monitoring glacial lakes and surrounding areas.
  • Regulation of Construction: Implement construction codes to regulate development in high-risk zones, exemplified by the 'Guidelines for the Construction of Earthquake Resistant Buildings' developed by the NDMA.
  • Capacity Building Initiatives: Enhance skills and resources through training programs conducted by institutions like the National Centre for Disaster Management, in collaboration with the private sector and NGOs.
  • Infrastructure Development: Invest in infrastructure to redirect potential floodwaters away from communities and critical infrastructure.
