2023 Badakhshan earthquake

2023 Badakhshan earthquake
On 21 March 2023, a magnitude 6.5 earthquake struck Badakhshan Province, Afghanistan, with an intermediate depth of approximately . The epicenter of the earthquake was south-southeast of Jurm.
Tectonic setting
The Himalayas, partially formed by the collision of tectonic plates, are prone to devastating earthquakes. Afghanistan is situated near the southern extent of the Eurasian Plate. Most of these earthquakes are associated with reverse, thrust, or strike-slip faulting. Large earthquakes with magnitudes of up to 7.5 have occurred in the region with an average recurrence interval of 15 years. These earthquakes correspond to reverse faulting at a depth of . These earthquakes, rather than occurring at a plate boundary, are sourced from within the Indian Plate as it dives beneath the Hindu Kush. As the tectonic slab of the Indian Plate descends at a near-vertical angle into the mantle, it stretches and begins to "tear", eventually leading to a slab detachment. This action results in stress accommodation along faults that produces earthquakes when ruptured. Smaller shallow focus earthquakes are also observed in the region, particularly associated with north–south trending zones of right lateral strike-slip, such as the Chaman Fault, with an increasing degree of shortening to the north, together accommodating the highly oblique convergence between the Indian and the Eurasian Plates.
Earthquake
The United States Geological Survey reported a magnitude of 6.5, while the Pakistan Meteorological Department said the earthquake had a magnitude of 6.5. The earthquake was initially reported inaccurately as 7.7. Shaking was felt over an area wide by approximately 285 million people in Pakistan, India, Uzbekistan, Tajikistan, Kazakhstan, Kyrgyzstan, Afghanistan, and Turkmenistan, according to the European-Mediterranean Seismological Centre.

There was also a fatality in Bajaur District. Buildings were damaged in Rawalpindi, including six which were deemed in risk of collapse and were evacuated. Two people were injured and another two went unconscious in the city, all due to panic. In Abbottabad, one person died from panic and fear. In Mardan District, the wall of a police station collapsed, causing an injury. Five people were injured in Swabi District. Dozens of houses collapsed and 40 people were injured in Buner District.

Tremors from the earthquake were felt across parts of North India, particularly in Jammu and Kashmir, Punjab, Himachal Pradesh, Haryana, Rajasthan, Uttarakhand and the National Capital Region. Disruptions of electricity and mobile services occurred in some parts of Jammu and Kashmir. A woman was injured after her house collapsed in Poonch, with reports of cracks in other houses and a wall collapse in the town and in the neighboring Nowshera. Cracks were reported in some houses in the state capital Srinagar. In Delhi, some buildings were reported to have cracked or tilted.
