Question

How do scientists determine where an earthquake starts?

Answer 1

Scientists use a method called triangulation to determine where the earthquake was. It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake.

Answer 2

Answer:

They can find the starting point of earthquake by seismometer

Explanation:

The epicenter of earthquake can be found by calculating the distance of seismometer and the  time taken by it to reach the siensmometer. The meter is placed on a rock or somewhere where the surface is not shaky and a firm reading could be taken. They should be placed away from noise sources like traffic noise or any other noise. There are two types of waves that are taken into consideration. These waves are called P waves and S waves which are responsible for determining the location of the earthquake.
