Answer 1

An earthquake's magnitude is a measure of how much energy an earthquake releases. Typically, the richter scale is used.

Answer 2

The amount of the energy released at earthquake source.

Step-by-step explanation:

Earthquakes are measured in two different ways.

• Based on magnitude which is the amount of the energy released at earthquake source.
• Based on intensity which is the quantification of how much of the ground shakes at the location.

Measurements on moment magnitude scale are determined using complex mathematical formula to convert the motion recorded with seismometer into the number which represents amount of energy released during earthquake.
