Question

The news media often report an earthquake's magnitude on the Richter scale. Which of the following items are characteristics of a Richter earthquake magnitude? Choose one or more:
(A) determined from the amplitude recorded by a single seismometer
(B) determined from the amplitude recorded by several seismometers
(C) uses a logarithmic scale
(D) calculated using area on the fault that slipped
(E) represents the amount of energy released
(F) determined using damage done by the earthquake

Answer 1

Answer:

(A) determined from the amplitude recorded by a single seismometer

(C) uses a logarithmic scale

(E) represents the amount of energy released

Explanation:

Richter scale -

It is the scale which is required to determine the power of the earthquake .

Richter scale work as a sesimogram .

It is a logarithmic scale , as every 1 increase on the Richter scale means the increase by a factor of 10 .

The amount of energy released can be measured with the help of Richter scale .

Hence , the correct options are (A) , (C) and (E) .
