The death toll has risen to 1,805 and another 4,718 people have been injured as a result of the earthquake, Reuters cited Nepal’s Home Ministry official. Many of the victims were in the Kathmandu Valley at the time the quake struck.

The epicenter of the quake was 80 kilometers northwest of Kathmandu, a city with a population about 1 million. It was at a depth of 31km.

The shallowness of the quake made it even more destructive as buildings were toppled and large cracks opened in roads.

Thousands in Katmandu are to spend the night outside their homes – in makeshift tents, eating food provided by volunteers – in anticipation of more tremors.

Tremors have also been felt in some cities in eastern and northern India, including the capital, New Delhi, said JL Gautam, Head Operations Seismology of Indian Meteorological Department (IMD).

The death toll from the earthquake in India has reached 36 people, according to Reuters, with the maximum number of deaths recorded in West Champaran district.

Tremors were also felt in Chinese Tibet where 12 people were killed, with four fatalities also recorded in Bangladesh.

A total of about 14 aftershocks of varying magnitude have jolted Nepal since the main earthquake. They were felt for more than two hours after the quake.

"Rescue efforts are still underway. We fear that the toll might rise as we dig through the rubble," he added.

The historic Dharahara (Bhimsen) Tower, dating back to 1832, collapsed in Kathmandu. The 62-meter-high monument was a part of Architecture of Kathmandu recognized by UNESCO.

As the Nepal’s authorities appealed for international assistance, Indian Prime Minister, Narendra Modi, dispatched a military air transporter with three tons of supplies and a disaster response team.

Three more aircraft were expected to follow the first flight, bringing a mobile hospital and more rescue workers.

The quake caused an avalanche on Mount Everest and killed 10 people, Gyanendra Shrestha of the Tourism Ministry in Kathmandu said.

"The toll could go up, it may include foreigners as well as Sherpas [native people who often act as guides]," he added.

About 1,000 climbers, including 400 foreigners, had been at camp or on Everest when the quake hit.

Nepal, which is situated in a mountainous area between India and China, is no stranger to natural disasters, with its worst earthquake killed more than 8,500 people in 1934.
