Nepal sits in between the two massive tectonic plates that collided to build the Himalayas. When they collide it also causes eartquakes .Nepal is particularly likely to get earthquakes. It sits on the boundary of two massive tectonic plates – the Indo-Australian and Asian plates. It is the collision of these plates that has made the Himalaya mountains, and also earthquakes.The April 25 quake measured 7.8 on the moment magnitude scale, the largest one since the 1934 Bihar quake, which measured 8.2 and killed about 10,000 people. Another quake in Kashmir in 2005, measuring 7.6, killed about 80,000 people.Earthquakes occur when strain builds up in Earth’s crust until it gives away, usually along old fault lines. In this case the strain is built by the collision or convergence of two plates.
Nepal’s army chief has warned the number of deaths from Saturday’s devastating 7.8-magnitude earthquake could reach 15,000. The toll now stands at over 6,000, with almost double that number injured. Hundreds of thousands have been left homeless. Thousands of survivors slept in tents this week rather than risk returning to damaged homes capable to collapsing in an aftershock. The World Food Program warns 1.4 million people require emergency food assistance, and the United Nations estimates 1.3 million children are in urgent need of humanitarian aid. The quake opened massive rifts in roads and destroyed historic structures, including the 19th century Dharahara Tower in the capital Kathmandu, which was packed with sightseers when it collapsed.

A month after the disaster that killed more than 8,000 people and left thousands injured and homeless, Chapagaun, which is half an hour’s drive from Kathmandu, remains a village trapped in an anxious limbo. Many of the houses that did not give in to the quake and the dozens of aftershocks that have followed are too badly cracked to be safe and their owners too scared to set foot in them.
With no permanent shelter, 200 villagers have established a camp in a square, where they eat and sleep together. While the men scavenge the left overs and try to demolish them brick-by-brick, the women work if they can. Children play in child-friendly spaces (CFSs), hundreds have been set up across Nepal by NGOs. Part-creche, part-school and part-psychosocial treatment centre, the spaces are designed to give children a piece of a normal life destroyed by the quake.
This are pictures to show the devastation of the Nepal Earthquakes. I hope this helped you understand the damage and science behind these earthquakes. Here is also a link to a fun game to help you prepare for a earthquake if you had one in your area.
