Pakistan in the most active quake zone, says US Geological SurveyArchive
WASHINGTON: A reverse faulting at immediate depths about 210 km below the Hindu Kush Range in north-eastern Afghanistan caused Monday’s earthquake in the Pak-Afghan region, according to the US Geological Survey.
In a report on the earthquake and its causes, the USGS said the rupture occurred on either a near-vertical reverse fault or a shallowly dipping thrust fault. At the latitude of the earthquake, the Sub-continent moves northward and collides with Eurasia at a velocity of about 37 millimetres per year.
Active faults and their resultant earthquakes in northern Pakistan and adjacent parts of India and Afghanistan are the direct result of convergence between the South Asian and Eurasia plates.
This collision causes an uplift that produces the highest mountain peaks in the world like the Himalayas, the Karakoram, the Pamir and the Hindu Kush ranges.
