Seismograms A, B, C, and D. show, in Greenwich time, the arrival times of the. earthquake waves at the four stations. The P-wave generated by this earthquake took 2 minutes. and 40 seconds to reach one of the seismic stations.
FICTION: âMega Quakesâ can really happen. The magnitude of an earthquake is related to the area of the fault on which it occurs - the larger the fault area, the larger the earthquake. The San Andreas Fault is 800 miles long and only about 10-12 miles deep, so that earthquakes larger than magnitude 8.3 are extremely unlikely.
