Question

The strenght of an earthquake depends in part on

Answer 1

Answer: The logarithm of the amplitude of waves recorded by seismographs.

Explanation:

(Sorry if it’s wrong! I don’t remember it super well, but I think this is it. Also, here’s a picture.)

Answer 2

Answer and Explanation:

Magnitude is related to the amount of seismic energy released at the hypocenter of the earthquake. It is based on the amplitude of the earthquake waves recorded on instruments which have a common calibration. The magnitude of an earthquake is thus represented by a single, instrumentally determined value.
