Seismic waves Study guides, Revision notes & Summaries

Earthquakes occur when rock masses break and slip past one another along a fault. - ANSWERTrue Most seismic activity takes place along passive tectonic plate boundaries. - ANSWERFalse What does the Richter magnitude scale measure? - ANSWERThe magnitude of the Earth shaking during an earthquake Let's assume an earthquake occurs somewhere along the San Andreas fault. A seismograph based in Los Angeles, California monitors the earthquake. In which order will the seismic waves reach the se...
