A.The Richter scale magnitude is not directly connected with the real damages during earthquakes.The Modified mercali scale and Japanese Sindo scales are directly connected with the amount of damages .

well let’s look at each one logically

A, knowing how strong an earthquake is can let you make a prediction on damage (though it might be wrong at times)

B, the richter scale is a base 10 not a base 30 hmm this is looking like the likely suspect

C, this is exactly what the richter scale is designed to do so let’s assume that is what it measures.

D, This one is quite true, fewer things in area to destroy or more localized but same power of course the damage will be different.

Overall I’d say B, the richter scale is a base 10 scale. a 5.0 is 10 times the power of a 4.0 not 30 and in general energy increases for things like this are not THAT inefficient as they go up. Relatively speaking.
