Using borehole geophysical measurements in conjunction with laboratory studies, scientists study heat flow, stress, fluid pressure, and the mechanical behavior of fault-zone materials at seismogenic depths to yield improved models of the earthquake cycle.
Earthquake geology in the broad sense is the study of the history, effects, and mechanics of earthquakes within and on the Earth's crust.
Seismic waves from earthquakes, man-made sources both local and distant, computer generated simulations and geophysical surveys are used to determine local, crustal, mantle and core structures of the earth.
Strong motion seismology uses special sensors, called accelerometers, to record large-amplitude ground motions and the response of engineered structures to these motions.

Information on the impact of an earthquake using data about the shaking, the affected population, and the affected infrastructure.
Maps showing the distribution of shaking produced by an earthquake.
Earthquake Early Warning (EEW) uses existing seismic networks to detect earthquakes rapidly and send a warning ahead of destructive seismic waves.
