2.  The Nepal earthquake (also known as the Gorkha earthquake)
killed more than 8,000 people and injured more than 19,000. It
occurred at 11:56 NST on 25 April 2015 , with a magnitude of
7.8 Mw. Its epicenter was the village of Barpak, Gorkha district,
and its hypocenter was at a depth of approximately 15 km. It
was the worst natural disaster to strike Nepal since the 1934
Nepal- Bihar earthquake.
 Geophysicists and other experts had warned for decades that
Nepal was vulnerable to a deadly earthquake, particularly
because of its geology, urbanization, and architecture.

6.  The structure of a building or its skeleton, are subject
to shearing, bending, torsion, tension and
compression during an earthquake. Buildings are
designed primarily to resist vertical forces from
gravity.
 The floor and support beams carry these forces down
to the support beams which in turn carry them to the
foundation and support soil.
 The failure of this during an earthquake can lead to
damage or even total building
collapse. Buildings made of steel and supported
concrete tend to withstand earthquake better.
