It occurred east of Kathmandu and its seismic focus lay at a depth of below the earth's surface. Over thirty-eight aftershocks of magnitude 4.5 Mw or greater occurred in the day following the initial earthquake, including the one of magnitude 6.8 Mw. According to the USGS, the earthquake was caused by a sudden thrust, or release of built-up stress, along the major fault line where the

According to Brian Tucker, founder of a nonprofit organization devoted to reducing casualties from natural disasters, some government officials had expressed confidence that such an earthquake would not occur again. Tucker recounted a conversation he had had with a government official in the 1990s who said, "We don't have to worry about earthquakes anymore, because we already had an earthquake"; the previous earthquake to which he referred occurred in 1934. In fact, the 600-km-long Central Himalayan Gap hadn't ruptured since 1505.

Based on a study published in 2014, of the Main Frontal Thrust, on average a great earthquake occurs every 750 ± 140 and 870 ± 350 years in the east Nepal region. 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 earthquake from 1934 in Nepal 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.

More direct effects

Some disasters that came with the monsoon season were suspected to be related to the earthquake. There was a landslip on 11 June, killing 53 people. Meanwhile, a glacial lake had burst in particularly hard hit Solukhumbhu district. Whether or not the quake had contributed to such events is often unknown and unresearched, but certainly possible.


Casualties


Nepal

The earthquake killed at least 8,857 people in Nepal and injured nearly three times as many. The rural death toll may have been minimized by the fact that most villagers were outdoors working when the quake hit. As of 15 May, 6,271 people, including 1,700 from the 12 May aftershock, were still receiving treatment for their injuries. Nearly 3.5 million people were left homeless. The example of this earthquake shows that loss calculations for hypothetical likely future earthquakes can be reasonably reliable. In 2005, the expected numbers of fatalities due to a hypothetical scenario earthquake near Kathmandu for M8.1 was published. The fatalities at that time were estimated between 21,000 and 42,000. The M7.8 earthquake of 25 April 2015 killed about 8,800 people because it occurred on a Saturday and so many buildings that collapsed, such as schools and municipal buildings, were empty, reducing the death toll. In addition, the epicentre of the earthquake was in a rural setting, so the worst hit districts had low population densities and most of the population was outside when the earthquake hit. Had the earthquake occurred at night or during the working week, when many more people were inside vulnerable buildings, the death toll would have likely been much closer to the modelled estimate. After the rupture area of the Kathmandu 2015 earthquake had been derived and the intensities of shaking had been mapped, a line source model for losses could be constructed with energy being radiated along the entire rupture. The fatalities estimated in this way by QLARM agree with those reported in the end. The figure shows reports of fatalities as a function of time. News reports significantly underestimated the actual numbers of fatalities for several days. ''

This is attributable directly to the effect of the earthquake, which caused widespread fracturing in the grounds of the Langtang area.

serving Kathmandu was closed immediately after the earthquake, but was re-opened later in the day for relief operations and, later, for some commercial flights. It subsequently shut down operations sporadically due to aftershocks, and on 3 May was closed temporarily to the largest planes for fear of runway damage. During strong aftershocks, the airport opened all boarding-lounge exit doors onto the tarmac, allowing people who were waiting post security and immigration to flee to the open spaces of the runway tarmac. Many remained outside as planes were delayed and the airport swelled to capacity. 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. Several

Economic loss

Concern was expressed that harvests could be reduced or lost this season as people affected by the earthquake would have only a short time to plant crops before the onset of the

estimated that it would need to spend about four times more than it currently does annually on infrastructure through to 2020 to attract investment. The U.S. Geological Survey initially estimated economic losses from the tremor at 9 per cent to 50 per cent of gross domestic product, with a best guess of 35 per cent. "It's too hard for now to tell the extent of the damage and the effect on Nepal's GDP", according to Hun Kim, an Asian Development Bank (ADB) official. The ADB said on the 28th that it would provide a US$3 million grant to Nepal for immediate relief efforts, and up to US$200 million for the first phase of rehabilitation.

Social effects

It was reported that the survivors were preyed upon by human traffickers involved in the supply of girls and women to the brothels of South Asia. These traffickers took advantage of the chaos that resulted from the aftermath of the earthquake. The most affected were women from poor communities who lost their homes. In response to the unsafe conditions of the temporary campsites, international organizations implemented Safety Committees which were provided cash grants for necessities like additional toilets and bathrooms.


Most affected

Single women had very little access to relief, according to a report by the Inter-party Women's Alliance (IPWA). The report also found that violence and rapes against women and minors has increased after the earthquake. Additionally, the earthquake has significantly affected certain groups of people. Tibeto-Burman peoples were hardest hit as they tend to inhabit the higher slopes of mountains as opposed to the central valleys and are less educated and connected. All of these factors make them harder to access. According to a government survey, malnutrition in children has worsened considerably some 3 months after the quake, with the most undernourished being

Rainfall and aftershocks were factors complicating the rescue efforts, with potential secondary effects like additional landslides and further building collapses being concerns.

were able to start medically evacuating the critically wounded by helicopter from outlying areas, initially cut-off from the capital city, Kathmandu, and treating others in mobile and makeshift facilities. There was concern about epidemics due to the shortage of clean water, the makeshift nature of living conditions and the lack of toilets. Emergency workers were able to identify four men who had been trapped in rubble, and rescue them, using advanced heartbeat detection. The four men were trapped in up to ten feet of rubble in the village of Chautara, north of Kathmandu. An international team of rescuers from several countries using FINDER devices found two sets of men under two different collapsed buildings.

, were already charting the densely populated Kathmandu Valley, and then focused on earthquake relief. "They were doing an inventory in the poorer communities where they didn't have a very good sense of the quality of buildings," says Cowan, whose students helped add Kathmandu's buildings and roads to OpenStreetMap. First responders, from Nepalese citizens to the Red Cross, the Nepal army and the United Nations used this data. The Nepal earthquake crisis mapping utilized experience gained and lessons learned about planning emergency aid work from earthquakes in Haiti and Indonesia. India pledged to donate $1 billion in cash and materials to Nepal. India's External Affairs Minister Sushma Swaraj said "I am happy to announce Government of India's pledge for Nepal's post-earthquake reconstruction of Nepali Rupees 10,000 crores, equivalent to one billion US dollars, one fourth of it as Grant." The International Conference on Nepal's Reconstruction has been organised by the Nepalese government to raise funds for rebuilding the country.

, roughly 45 miles (72 kilometres) east of Kathmandu. Two Nepalese soldiers and six American Marines died in the crash. Need-fulfillment application, Getmii, launched a special pilot version in partnership with the Red Cross to double daily blood donors at the Kathmandu donation center using the app. Imaging technologies such as satellites and smartphones, were instrumental to relief efforts in Nepal. GLIMS, group of volunteer scientists from nine nations, were able to provide rapid, systematic mapping of the damaged area, allowing the investigation of earthquake-induced geo-hazard processes that provided information to relief and recovery officials on the same timeframe as those operations were occurring. Charities and Crowdfunding platforms received over $230 million in donations from support groups. The money was used to provide medical supplies, for reconstruction of damaged buildings including schools and hospitals, and building orphanages for the victims among other things.


Repair and reconstruction


Monuments

UNESCO and the Ministry of Culture began strengthening damaged monuments in danger of collapsing before the monsoon season. Subsequent restoration of collapsed structures, including historic houses is planned. Architectural drawings exist that provide plans for reconstruction. According to UNESCO, more than 30 monuments in the Kathmandu Valley collapsed in the quakes, and another 120 incurred partial damage. Repair estimates are $160 million to restore 1,000 damaged and destroyed monasteries, temples, historic houses, and shrines across the country. The destruction is concentrated in the Kathmandu Valley. UNESCO designated seven groups of multi-ethnic monuments clustered in the valley as a single World Heritage Site, including Swayambhu, the three squares namely Durbar square of Kathmandu,

. Damaged in the quakes were the structures in the three Durbar squares, the temple of Changu Narayan, and the 1655 temple in Sankhu. Drones fly above cultural heritage sites to provide 3D images of the damage to use for planning repairs.


Nepal Rural Housing Reconstruction Program

After an international donors conference held in Kathmandu on 25 June 2015 a multi donor trust fund of US$4.4 billion was established to aid the reconstruction of affected housing in 14 districts of Nepal. This covered 66 per cent of the country's total recovery and reconstruction needs of US$6.7 billion. Implementation of the Program consisted of five phases i.e. Survey, Identification and Validation, Enrollment, Reconstruction and Completion. The data collection for the program was done digitally using tablets and resulted in collection of over 10 TB of data. The data was openly released to the public by the National Planning Commission and is available for download on their website.


International aid

A total of $3bn was pledged by donors to help rebuild Nepal.

said close to 1.7 million children had been driven out into the open, and were in desperate need of drinking water, psychological counsel, temporary shelters, sanitation and protection from disease outbreak. It distributed water, tents, hygiene kits, water purification tablets and buckets. Numerous other organizations provided similar support. 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. They faced challenges in both getting assistance to Nepal and ferrying people to remote areas as the country had few helicopters. Relief efforts were also hampered by Nepalese government insistence on routing aid through the Prime Minister's Disaster Relief Fund and its National Emergency Operation Center. After concerns were raised, it was clarified that "Non-profits" or NGOs already in the country could continue receiving aid directly and bypass the official fund. 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 on heavy aircraft flying in aid supplies after new cracks were noticed on the runway at the
