In general, earthquake intensity is greatest in areas underlain by sediment.
When two earthen blocks abruptly slide past one another, it causes an earthquake. Fault or fault plane refers to the area where they slide. An earthquake's severity is quantified by its intensity, which is a number (written as a Roman numeral), which includes consequences on people, structures, and the earth's surface.
There are many different scales, for earthquake measurement but the Rossi-Forel scale and the Modified Mercalli scale are the two that are most frequently used in the US. The amount of soft soil that can be penetrated by seismic waves increases with the depth of the sediment layer above the bedrock. Greater wave size and amplification result from soft soil. To put it simply, the softer and thicker the soil, the higher the shaking or wave amplification.
