The 2011 Sikkim earthquake (also known as the 2011 Himalayan earthquake) occurred with a moment magnitude of 6.9 and was centered within the Kanchenjunga Conservation Area, near the border of Nepal and the Indian state of Sikkim, at on Sunday, 18 September. The earthquake was felt across northeastern India, Nepal, Bhutan, Bangladesh and southern Tibet. At least 111 people were killed in the earthquake.〔(Himalayan quake toll climbs to 116, 40 stranded foreign tourists rescued ), DNA, 21 September 2011〕 Most of the deaths occurred in Sikkim, with reports of fatalities in and near Singtam in the East Sikkim district.〔(Earthquake claims two lives in Sikkim ), The Hindu, 18 September 2011〕 Several buildings collapsed in Gangtok. Eleven are reported dead in Nepal, including three killed when a wall collapsed in the British Embassy in Kathmandu.〔(Earthquake kills 5 in Nepal ), DNA, 18 September 2011〕 Elsewhere, structural damage occurred in Bangladesh, Bhutan, and across Tibet; another seven fatalities were confirmed in the latter region. The quake came just a few days after an earthquake of 4.2 magnitude hit Haryana's Sonipat district, sending tremors in New Delhi. The earthquake was the fourth significant earthquake in India of September 2011. Exactly a year after the original earthquake at 5:55 pm on 18 September 2012, another earthquake of magnitude 4.1 struck Sikkim, sparking panic among the people observing the anniversary of the original quake.〔〔(【引用サイトリンク】title=Geological Survey of India )〕 ==Earthquake== The magnitude 6.9 (Mw) earthquake occurred inland at 18:10 IST on 18 September 2011, about 68 km (42 mi) northwest of Gangtok, Sikkim at a shallow depth of 19.7 km (12.2 mi).〔 At its location, the continental Indian and Eurasian Plates converge with one another along a tectonic boundary beneath the mountainous region of northeast India near the Nepalese border. Although earthquakes in this region are usually interplate in nature, preliminary data suggests the Sikkim earthquake was triggered by shallow strike-slip faulting from an intraplate source within the over-riding Eurasian Plate. Initial analyses also indicate a complex origin, with the perceived tremor likely being a result of two separate events occurring close together in time at similar focal depths. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2011 Sikkim earthquake」の詳細全文を読む スポンサード リンク
