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 ...
An isoseismal line is a contour line on a map that connects locations experiencing the same intensity of earthquake shaking. These lines help scientists visualize the distribution of damage and the impact of local soil conditions on seismic energy. They ...
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 ...
