Factbox: Quake in Afghanistan is its deadliest in two decades

Afghanistan’s deadliest earthquake in two decades killed at least 920 people near the southeastern city of Khost on Wednesday, officials have said.

The country has a long history of earthquakes, many in the mountainous Hindu Kush region bordering Pakistan.

Death tolls have been worsened by the remote locations of many quakes and decades of war that have left infrastructure in perilous condition.

Here is a list of Afghan quakes that have killed more than 100 people over the last three decades, according to the US government’s National Centers for Environmental Information:
