An earthquake is what happens when two blocks of the earth suddenly slip past one directly above it on the surface of the earth is called the epicenter. Today, most seismologists no longer follow Richter's original methodology because it does not give reliable results when applied to stronger earthquakes and it was not designed to use data from earthquakes recorded at epicentral distances greater than ~600 km. The instrument detects and documents the intensity, direction and duration of ground vibrations, which are used to determine the epicenters and strength/magnitudes of earthquakes or other seismic events. The hypocenter is the point within the earth where an earthquake rupture starts. Considered best for measuring small earthquakes (3.5 M or less). Use this information to complete the following.
