Question

Which is used to find the epicenter of an earthquake?

magnitude
seismic waves
seismograph
seismometer

Answer 1

This number will be used to tell you how far your seismograph is from the epicenter of the earthquake. Measure the distance between the first P wave and the first S wave. In this case, the first P and S waves are 24 seconds apart.

answer: seismograph

Answer 2

Seismograph is used to depict the epicentre of an earthquake.

Answer: Option C

Explanation:

Seismograph gives the details of force and duration of earthquakes occurred. It consists of mass attached to fixed base. The mass remains constant and the base moves during earthquake.

Electric voltage obtained is recorded on paper, magnetic tape by transforming the motion of base with respect to mass. Seismograph has a seismometer which is a single unit recording device.
