An earthquake is one of the most horrendous natural disasters that affect millions of people around the world.
Science and technology play an important role in disaster management to counter the damaging effects. It is possible to determine the magnitude of an earthquake with the help of an earthquake warning system.
A seismometer measures the motions of the earth and an accelerometer measures the acceleration of that motion to determine the magnitude of an earthquake. Computers display this data in an analytical format.
Authorities are alerted to the severity of the disaster by the data displayed on computers. Based on the warning system, the rescue operation is initiated more comprehensively.
