| Comments | At least 1,567 people killed, 2,300 injured, 50,000 homeless, 10,533 houses destroyed, 5,474 houses damaged and landslides in the Birjand-Qayen area. Five people killed and some damage in the Herat area, Afghanistan. Felt in Kerman, Khorasan, Semnan, Sistan va Baluchestan and Yazd Provinces, Iran. This earthquake appears to have occurred on a southern splay of the Ferdows fault. The left-lateral, strike-slip Ferdows fault was the site of the 1968 Dasht-e-Bayaz earthquake (magnitude 7.3) which resulted in 12,000-20,000 casualties. The Ferdows fault is north of the Zagros Mountains (the latter being the northern boundary of the Arabian plate). Understanding the tectonics of the Ferdows region is complicated by indistinct boundaries of the several microplates at that collision zone. |

The region name is an automatically generated name
from the Flinn-Engdahl (F-E) seismic and geographical regionalization scheme.
The boundaries of
these regions are defined at one-degree intervals and therefore differ from
irregular political boundaries.
