Earthquakes are destructive natural disasters. Generally, earthquakes typically only last for a few brief moments but they can greatly impact a society. Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. Seismic waves are produced when some forms of energy stored in Earth’s crust are suddenly released. Earthquakes occur most often along geologic faults.

One of which include the Nepal Earthquake of April 25,2015. This particular earthquake flattened large parts of the capital Kathmandu. The earthquake in Nepal was the most catastrophic natural disaster in the last 80 years.

Most earthquake injuries and fatalities aren’t actually caused by the ground shaking. Instead, it’s when buildings and other structures collapse, as a result of the shaking.
An earthquake happens somewhere every single day. The U.S. Geological Survey (USGS) estimates that 500,000 detectable earthquakes occur in the world each year. Many more go undetected because they hit remote areas or have very small magnitudes. The National Earthquake Information Center (NEIC) locates an average of 50 earthquakes every day, or about 20,000 a year.
