Earthquakes

The initial quake at 10:49 (03:49 UTC) measured 6.4 on the moment magnitude scale and the second quake at 12:49 (05:49 UTC) measured 6.3. [4] [5] The earthquakes were felt as far away as Singapore and Malaysia, which prompted the evacuation of some buildings there. [6]

Effects

Over 60 fatalities and 460 serious injuries have been reported, spread across many towns and regencies in West Sumatra. [3] Over 43,000 houses were damaged, with over 12,000 of those severely damaged. [7] The severe damage to other structures includes over 130 public facilities, 310 mosques, 60 government buildings, 370 schools, and 230 shops. [7] According to the governor of West Sumatra, Agam Regency is the worst affected area, though other areas including Solok Regency and Tanah Datar are also badly affected. [8] The total value of damage is estimated to be around 1.4 trillion Indonesian rupiah (US$160 million). [7]

Response

A variety of local and international aid organizations have deployed to the region to assist victims. A number of countries have pledged aid, including the Netherlands (US$2.0 million), Sweden (US$1.0 million), Canada (US$0.21 million), Malaysia (US$0.16 million), United States (US$0.1 million) and Taiwan (US$0.06 million). The US AID has supplied them with all sorts of essentials like blankets, water, food and first aid kits.

The 2005 Hindu Kush earthquake hit northeastern Afghanistan with a magnitude of 6.5 on December 12 at 21:47 (UTC). According to the United States Geological Survey, the maximum Mercalli intensity was V (Moderate) at Chitral. Five people were killed in the Hindu Kush region and landslides blocked several roads near Bagh, Kashmir. The earthquake occurred some 65 miles away from Faizabad, a city in the Hindu Kush mountains, but it could be felt in many neighboring areas. It could even be felt about 200 miles away in Islamabad, Pakistan. The quake was strong enough to trigger panic among survivors of October's devastating earthquake, who came out from their makeshift shelters in freezing temperatures. Although magnitude–6 earthquakes typically cause severe damage, this quake caused relatively little due to the fact that it occurred deep underground.

An earthquake occurred at 08:50:39 Pakistan Standard Time on 8 October 2005 in Azad Jammu and Kashmir, a territory under Pakistan. It was centred near the city of Muzaffarabad, and also affected nearby Balakot in Khyber Pakhtunkhwa and some areas of Jammu and Kashmir, India. It registered a moment magnitude of 7.6 and had a maximum Mercalli intensity of XI (Extreme). The earthquake was also felt in Afghanistan, Tajikistan, India and the Xinjiang region. The severity of the damage caused by the earthquake is attributed to severe upthrust. Over 86,000 people died, a similar number were injured, and millions were displaced. It is considered the deadliest earthquake in South Asia, surpassing the 1935 Quetta earthquake.
