Question

The Richter magnitude of an earthquake is determined from the _____.

duration of an earthquake

measurement of the amplitude of the largest seismic waves

intensity of an earthquake

measurement of the arrival times of P waves and S waves

Answer 1

Answer:

Measurement of the amplitude of the largest seismic waves.

Explanation:

The Richter magnitude scale was developed as a mathematical device to compare the size of earthquakes.

Answer 2

A Richter scale helps us measure or determine the magnitude of the earthquake. It does this with the help of a seismograph. That records earthquake waves.

• Thus its functions as a log for the amplitude of the earthquake waves. The large the number the higher is the increase in magnitude of the earthquake.

• Hence an earthquake that is of 7.0 magnitude on the Richter scale is 10 times stronger than an earthquake of 6.0 magnitude.

Hence the option B is correct.
