Magnitude 4.5 Earthquake in Takhar Province, Afghanistan.

The United States Geological Survey recorded a Magnitude 4.5 Earthquake at a depth of 137.4 km in Takhar Province, Afghanistan, slightly after 10.45 pm local time (slightly after 6.15 pm GMT) on Monday 11 March 2019. Quakes at this depth are seldom dangerous, but are often felt over a wide area, and this one was reportedly felt from Panjshir Province in the south, as far north as Dushanbe in Tajikistan.

The boundary between the Indian and Eurasian tectonic plates runs through northern Afghanistan. The Indian Plate is moving northward relative to the Eurasian Plate, causing folding and uplift along this boundary, which has led to the formation of the Hindu Kush Mountains of Afghanistan, the Himalayas and the other mountain ranges of Central Asia., and which makes the nations in this boundary zone prone to Earthquakes.
