2013 Dingxi Earthquakes
As of 23:00 CST, 23 July 2013, the earthquakes had caused at least 95 deaths, and more than 2,300 people were injured.
Background
The tremor occurred less than 14 kilometres (9 mi) from the Lintan-Dangchang fault line (Chinese: 临潭-宕昌断裂带). Since recorded history 25 earthquakes of more than 5.0 magnitude have occurred within a 200 kilometres (124 mi) radius from the current epicenter, the earliest being the 193 BC Lintao earthquake which measured at 6.5 magnitude, while the strongest was the 8.0-magnitude 1654 Tianshui earthquake.
Effects
Most of the casualties occurred in Min County, located 15 kilometres (9 mi) from the epicenter, which reported 87 deaths.
According to the Gansu provincial officials, more than 1,200 buildings have collapsed and over 21,000 severely damaged. Many local buildings, often crudely constructed, were buried in the landslides caused by the earthquakes. Within the disaster zone, 20% of the buildings have collapsed and 60% are damaged. 27,360 people are estimated to have been displaced in Zhang County alone.
Communication was cut off to 13 townships in Zhang County and many villages in Meichuan, Min County. Five towns in eastern Min County have lost power.
