Web"Foreshock" and "aftershock" are relative terms. Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs. Aftershocks are smaller earthquakes that occur in the same general area during the days to years following a … WebSeismic waves lose much of their energy in traveling over great distances. But sensitive detectors (seismometers) can record theses waves emitted by even the smallest …
WebAn earthquake releases energy as shock waves, the so-called seismic waves, which ripple across the earth's surface. The seismic waves created as they move from the epicentre an earthquake vary. What is amazing …
WebNARRATOR: Earthquakes generate two main types of seismic, or shock, waves: body waves and surface waves. Body waves travel through the interior of the earth. The fastest of these are primary, or "P," waves. These compressional waves move faster in dense rock and slower in fluids.
