The Richter scale “saturates” (fails to distinguish) between very large earthquakes (above 7.0) because it only measures peak wave amplitude. The Moment Magnitude Scale (Mw) measures the total energy by considering the fault area and the amount of slip, providing ...

While erosion, volcanoes and weathering are processes that occur directly on or from the terrestrial surface, a Tsunami is a phenomenon that originates underwater (on the seafloor). Although its effects are felt on the coast, the “event” itself is a ...
The line connecting places in a region where an earthquake is experienced at the same time is technically called a Coseismal line. It maps the “arrival time” of seismic waves. However, in many contexts, the isoseismal line is used to ...
Statement (D) is incorrect because isoseismic lines are almost always irregular. They connect points of equal earthquake intensity, which depends on local geology, soil type and building density. Since ground conditions and rock types vary significantly across a region, the ...
The epicenter is the point on the Earth’s surface located vertically above the earthquake focus (hypocenter). It is the location typically cited in news reports and maps to indicate where the earthquake occurred. It is generally the area where the ...
