WebbThe point at which fault slipping begins is referred to as the focus of the earthquake. [4] The fault rupture begins at the focus and then expands along the fault surface. The rupture stops where the stresses become insufficient to continue breaking the fault (because the rocks are stronger) or where the rupture enters ductile material. [4] WebbWhen an earthquake occurs, it generates an expanding wavefront from the earthquake hypocenter at a speed of several kilometers per second. We observe earthquakes with a network of seismometers on the earth's surface. The ground motion at each seismometer is amplified and recorded electronically at a central recording site. crystal springs medical building roanoke va
