April 2015 Nepal earthquake The April 2015 Nepal earthquake (also known as the Gorkha earthquake)[8] killed 8,962 people and injured 21 952 across Nepal, India, China and Bangladesh. It occurred at on 25 April. The earthquake had a magnitude of 7.8Mw.[9] Its epicenter was east of the district of Lamjung. Its hypocenter was at a depth of about 15 km (9.3 mi).[1] It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake.[10][11] The earthquake triggered an avalanche on Mount Everest, killing at least 19 people.[12] This makes April 25, 2015 the deadliest day on the mountain in history.[13] The earthquake triggered another huge avalanche in the Langtang valley, where 250 people were reported missing.[14] Hundreds of thousands of people were made homeless with entire villages destroyed.[15] Centuries-old buildings were destroyed at UNESCO World Heritage Sites in the Kathmandu Valley. Experts had warned for decades that Nepal was vulnerable to a deadly earthquake.[16] Continued aftershocks occurred throughout Nepal within 15–20 minute intervals. One shock reached a magnitude of 6.7 on 26 April at NST. The April 2015 Nepal earthquake (also known as the Gorkha earthquake) killed 8,962 people and injured 21,952 across the countries of Nepal, India, China and Bangladesh. It occurred at 11:56 Nepal Standard Time on Saturday 25 April 2015, with a magnitude of Mw 7.8–7.9 or Ms 8.1 and a maximum Mercalli Intensity of X (Extreme). Its epicenter was east of Gorkha District at Barpak, Gorkha, roughly 85 km (53 mi) northwest of central Kathmandu, and its hypocenter was at a depth of approximately 8.2 km (5.1 mi). It was the worst natural disaster to strike Nepal since the 1934 Nepal–India earthquake. Continued aftershocks occurred throughout Nepal at intervals of 15–20 minutes, with one shock reaching a magnitude of 6.7 on 26 April at 12:54:08 NST. The country also had a continued risk of landslides. A major aftershock occurred on 12 May 2015 at 12:50 NST with a moment magnitude (Mw) of 7.3. The epicenter was near the Chinese border between the capital, Kathmandu, and Mount Everest. More than 200 people were killed and over 2,500 were injured by this aftershock, and many were left homeless. A study from 2015 found a 700-year delay between earthquakes in the region. The study also suggests that because of tectonic stress buildup, the 1934 earthquake and the 2015 quake are connected, following a historic earthquake pattern. A 2016 study on historical great (M ≥ 8) earthquake pairs and cycles found that associated great earthquakes are likely to occur in the West China region through the 2020s. === Intensity === According to the USGS website, the maximum intensity was VIII (Severe), however certain reports state an intensity of X (Extreme) or higher. The earthquake was also experienced across southwest China, ranging from the Tibet Autonomous Region to Chengdu, which is 1,900 km (1,200 mi) away from the epicenter. Tremors were felt in Pakistan and Bhutan. === Aftershocks === A series of aftershocks began immediately after the mainshock, at intervals of 15–30 minutes, with one aftershock reaching 6.6Mw within 34 minutes of the initial quake. A major aftershock of magnitude 6.9 Mw occurred on 26 April 2015 in the same region at 12:54 NST (07:08 UTC), with an epicenter located about 17 km (11 mi) south of Kodari, Nepal. The Himalayan Times reported that as many as 20,000 foreign nationals may have been visiting Nepal at the time of the earthquake, although reports of foreign deaths were relatively low. ==== India ==== A total of 78 deaths were reported in India – including 58 in Bihar, 16 in Uttar Pradesh, 3 in West Bengal and 1 in Rajasthan. ==== China ==== Twenty-seven people were confirmed dead, 383 were injured and 4 were missing, all from the Tibet Autonomous Region. The quake destroyed 2,500 houses and damaged 24,700 others across 19 counties in Tibet, affecting nearly 300,000 people, among whom 47,500 were displaced, while a total of 82 temples were also damaged. The airport facilities suffered damage and there was no running water or operating toilets in the airport lounges. Few airport workers were at their posts; most were killed in the earthquake or had to deal with its aftereffects. Flights resumed from Pokhara, to the west of the epicentre, on 27 April. Several of the churches in the Kathmandu valley were destroyed. As Saturday is the principal day of Christian worship in Nepal, 500 people were reported to have died in the collapses. India was the first to respond within hours, being Nepal's immediate neighbour, with Operation Maitri which provided rescue and relief by its armed forces. It also evacuated its own and other countries' stranded nationals. India has been the largest aid donor to Nepal following the earthquake with a billion dollar support apart from other non-monetary reliefs extended. China, the Asian Development Bank and the United Kingdom provided significant bilateral aid and other nations and organisations provided aid, rescue teams and helicopters as requested by the Nepalese government. On 26 April 2015, international aid agencies and governments mobilized rescue workers and aid for the earthquake. Aid mismatch and supply of "leftovers" by donors, aid diversion in Nepal, mistrust over control of the distribution of funds and supplies, congestion and customs delays at Kathmandu's airport and border check posts were also reported. On 3 May 2015, restrictions were placed The International Seismological Centre has a bibliography and/or authoritative data for this event. Nepal Earthquake Open Data Portal (Archived 17 January 2020 at the Wayback Machine) by National Planning Commission has structural and socioeconomic data of over 1 million household and 762 thousand buildings of districts most severely effected by the earthquake.
