GEOLOGY

Detailed explanation-1: -The Richter Scale is not used to express damage. An earthquake in a densely populated area which results in many deaths and considerable damage may have the same magnitude as a shock in a remote area that does nothing more than frighten the wildlife.

Detailed explanation-2: -In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.).

Detailed explanation-3: -The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake. The Richter scale doesn’t measure quake damage (see: Mercalli Scale) which is dependent on a variety of factors including population at the epicentre, terrain, depth, etc.

Detailed explanation-4: -The correct option is C 1. Richter scale measures magnitude of earthquake whereas Mercalli scale is used to measure the intensity of earthquake. 2. Magnitude of earthquake depends on the destruction caused by earthquake.

Detailed explanation-5: -The Richter scale is an outdated method for measuring magnitude that is no longer used by the USGS for large, teleseismic earthquakes. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
