Earthquakes can be detected by using a  seismometer.

Shock absorbers are devices that reduce the magnitude of an earthquake

Japan is also building many earthquake proof building

It is measured Volcanic Explosivity Index (VEI).The Volcanic Explosivity Index is determined by using one of more of the following criteria, height of the eruptive column, Qualitative descriptions (“gentle”, “effusive”, “explosive”, “cataclysmic”, etc.)

They can make buildings fall down and set off landslides. An earthquake that occurs at the bottom of the sea can push water upwards and create massive waves called tsunamis.

Earthquakes are usually caused when rock underground suddenly breaks along the side. This sudden release of energy causes the seismic waves that make the ground shake.
