Earth's formations help transfer energy from earthquakes

Shelley J. Kenner, AGU

Data from the 1906 San Francisco earthquake was used to model the transfer of accumulated stresses along the San Andreas fault line. It was found that the Earth's upper mantle and lower crust regions play a significant role in reloading a fault zone after an earthquake and that post-seismic activity can provide up to 80 percent of the stress released during large earthquakes. These observations are consistent with activity prior to the powerful 1906 quake.
