Deadly earthquake hits Afghanistan: What we know so far
Briefly

The magnitude 6 earthquake struck at 11:47pm (19:47 GMT) on Sunday, shaking Nangarhar and Kunar provinces in eastern Afghanistan. The quake was 8km deep, classifying it as a shallow tremor that increases surface damage. A magnitude 4.5 aftershock hit twenty minutes later north of Basawul, and numerous tremors ranging 4.3–5.2 followed near Jalalabad and Basawul. The USGS located the epicentre 27km east northeast of Jalalabad. Jalalabad, about 150km east of Kabul with roughly 300,000 residents, has mostly low-rise concrete and brick buildings and mud-brick outskirts. Flooding and rubble have obstructed rescue operations. The death toll stands at 812 with over 3,000 injured.
At 11:47pm (19:47 GMT) on Sunday, the earthquake shook Nangarhar and Kunar provinces in eastern Afghanistan. It was 8km (5 miles) deep, making it a shallow tremor. Shallower earthquakes tend to cause more damage because the epicentre of the quake and seismic waves are closer to the Earth's surface. Seismic waves from deep earthquakes have to travel a greater distance to get to the surface, which causes them to lose energy.
Twenty minutes after the first earthquake, a magnitude 4.5 earthquake hit north of Basawul in Nangarhar province. Since then, multiple tremors have struck near the provincial capital, Jalalabad, and Basawul with magnitudes ranging from 4.3 to 5.2. According to the United States Geological Survey (USGS), the initial earthquake was centred 27km (17 miles) east northeast of Jalalabad near Kunar province, which is located just north of Nangarhar.
