News<\/strong>:\u00a0This article discusses the reasons behind the phenomenon of frequent earthquakes in Afghanistan.<\/p>\n

Afghanistan has had a history of frequent destructive earthquakes. An earthquake of magnitude 6.3 struck western Afghanistan recently, barely a few days after multiple earthquakes killed at least a 1,000 people in the Herat province.<\/p>\n

How do earthquakes occur?<\/strong><\/h2>\n

Stage I: Movement of tectonic plates: <\/strong>The earth is made up of chunks of solid rocks called tectonic plates. Tectonic plates are slow moving but are always in motion, mostly due to the heat energy generated inside the earth.<\/p>\n

Stage II: Creation of Faults: <\/strong>Discontinuities in these plate rock masses, along which they have moved, are called fault lines. This is\u00a0where most earthquakes occur.<\/p>\n

Stage III: Release of Energy: <\/strong>The tectonic forces and stress that builds up in the earth\u2019s lithosphere causes the rocks to break and slip. This releases energy and sends seismic waves through the ground.<\/p>\n

Why do frequent earthquakes occur in Afghanistan?<\/strong><\/h2>\n

1) Afghanistan is located over multiple fault lines\u00a0in the region\u00a0where the Indian, Arabian and the Eurasian tectonic plates<\/strong> meet. These plates collide often, leading to significant tectonic activity.<\/p>\n

    \n
  1. a) Towards western Afghanistan<\/strong>, the Arabian plate<\/strong> subducts northward under Eurasia<\/strong>.<\/li>\n
  2. b) Towards eastern Afghanistan<\/strong>, the Indian plate<\/strong> subducts northward under Eurasia<\/strong>.<\/li>\n
  3. c) In southern Afghanistan<\/strong>, the Arabian and Indian plates adjoin and both subduct northward under the Eurasian plate.<\/li>\n<\/ol>\n

    2) Geological complexity: <\/strong>The Hindu Kush Mountain range and the Pamir Knot<\/strong> are geologically complex regions where tectonic plates meet.<\/p>\n

    3) Forces of Compression:<\/strong> The ongoing northward movement of the Indian Plate towards the Eurasian Plate also results in compression<\/strong>,\u00a0leading\u00a0to the transmission of tectonic stress across the entire region. The compression creates faults and fractures that can slip and generate earthquakes.<\/p>\n

    4) Presence of Faults: <\/strong>like the Chaman Fault and the Main Pamir Thrust.<\/p>\n","protected":false},"excerpt":{"rendered":"
