The 2008 Ziarat earthquakes hit the Pakistani province of

Balochistan mayor and chief administrator).[8][9] Qamar Zaman Chaudhry, director general of Pakistan Meteorological Department, stated the quake epicenter was 70 miles (110 km) north of Quetta,[10] and about 600 km (370 mi) southwest of Islamabad.[11]

Tectonic summary

Western and northern Pakistan lie across the complex plate boundary where the Indian Plate is colliding with the Eurasian Plate. In this area the convergence is highly oblique, with the relative northward movement of the Indian Plate of 40 mm/yr (1.6 inches/yr) being at a low angle to the plate boundary. The main active faults are dominated by sinistral (left-lateral) strike-slip motion, with the Chaman Fault being the most important structure, accommodating a large proportion of the plate boundary displacement. The shortening component of the convergence is mainly accommodated by the Kirthar and Sulaiman fold and thrust belts.[12] There is a sharp change in orientation of these two thrust belts near Quetta, known as the Quetta Syntaxis, where the north–south trending Kirthar ranges meet the west–east trending Sulaiman ranges. This area is the most seismically active part of this oblique segment of the plate margin, producing major earthquakes such as the 1935 Quetta event, which caused at least an estimated 30,000 deaths.[13]

Earthquake sequence

The earthquake sequence began at 22:33 UTC on October 28, with a magnitude 5.3 foreshock. This was followed just over 30 minutes later at 23:09 by the first of the M 6.4 doublet earthquakes. The second M 6.4 doublet earthquake occurred at 11:32 on October 29. There were five significant aftershocks in the period up to December 12, including three M>5 earthquakes on that day.[14]

The observed

InSAR data supported activity on multiple faults in both of these orientations.[13][15][14]

Damage

Most of the casualties were from two villages on the outskirts of Ziarat town. Balochistan chief minister Nawab Aslam Khan Raisani ordered declaration of emergency in the hospitals of the affected areas. These areas, situated on steep terrain, were badly damaged by landslides caused by the quake.[1] Hundreds of mud houses were destroyed.

"Rescue work is being carried out by the villagers themselves, but a larger operation is needed here."

Mayor of Ziarat Dilawar Kakar [16]

The tremors were felt in

Bolan, Kuchlak and Loralai areas.[16][17]

Response

Dilawar Khan, mayor of

Pakistani military helicopters and troops were dispatched to assess damage and aid victims.[1]
