2013 Pakistan earthquake

The 2013 Pakistan earthquake was a magnitude Mw 7.7 earthquake with an epicenter 66 kilometres (41 mi) north-northeast of Awaran in Balochistan. At least 370 people were killed and hundreds more were injured

The United States Geological Survey reported that the earthquake took place on 24 September 2013 at 11:29:48 UTC at 27.000°N, 65.514°E. The depth of the earthquake was reported to be 20 kilometres (12 mi). Pakistan's National Seismic Monitoring Centre reported the Mw 7.7 quake occurred at 16:29:49 PKT(UTC+5:00) at 27.09°N, 65.61°E at a depth of 10 km.[3] The earthquake reportedly lasted about a minute, causing panic in cities of southern Pakistan such as Karachi and Hyderabad.[4]
The earthquake was felt in major cities across Pakistan, including Karachi, Hyderabad, Islamabad, Larkana, and Lahore.[4] The quake was also felt in Delhi, India, where some buildings shook,[5] and Muscat, Oman—800 km from the epicenter—where mild tremors shook tables and cabinets.[6]

Effects and casualties
The earthquake killed at least 370 people and hundreds more were wounded.[1] PAGER impact estimates from the United States Geological Survey include a red alert level for initial shaking-related fatalities (35% chance of 1,000–10,000 fatalities, 27% chance of 10,000–100,000 fatalities) and an orange alert level for economic impact (35% chance of US$100 million-$1 billion, 26% chance of US$1–10 billion).[17]
The earthquake struck a sparsely populated region of Pakistan. Most homes and buildings in the region are constructed of mud bricks and collapsed during the earthquake and aftershocks. An official in the Baluchistan province claimed that 80 percent of the homes in the Awaran district had collapsed or were damaged.[1] In the regional capital Quetta, some areas appeared to be badly damaged.[18][19]
The earthquake was apparently powerful enough to raise a small island in the Arabian Sea off the shore of Gwadar. Early reports claim the new island is between 350 feet (110 m) to 1 mile (1.6 km) from the shore, with a height of 20–40 ft (6-12m) and about 100 feet (30 m) wide.[19][20]
