GEOLOGY

Detailed explanation-1: -Answer: Magnitude (Mw ) scale is a more accurate measure of the earthquake size. Explanation: Magnitude is another word for an earthquake’s strength.

Detailed explanation-2: -Magnitude is the size of the earthquake. An earthquake has a single magnitude.

Detailed explanation-3: -There are two ways by which we can measure the strength of an earthquake: magnitude and intensity. Magnitude is proportional to the energy released by an earthquake at the focus. It is calculated from earthquakes recorded by an instrument called seismograph. It is represented by Arabic Numbers (e.g. 4.8, 9.0).

Detailed explanation-4: -Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.

Detailed explanation-5: -Magnitude is the most common measure of an earthquake’s size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like.
