What is the focus of an earthquake?
Quick Answer
The focus is the underground point where an earthquake begins. It is also called the hypocenter.
The Full Story
The focus is the place along a fault where rocks suddenly break or slip, releasing seismic energy. From that point, seismic waves radiate outward in all directions. The depth of the focus matters because shallow earthquakes usually cause more surface damage than deep ones of similar size. Scientists use seismic wave patterns to estimate the focus location and depth after an event.
