Information on rock properties is combined with other geophysical observations to improve our models of the earthquake process, such as the timing and magnitude of earthquakes, earthquake triggering, recurrence, rupture propagation, and ground motion. This in turn is necessary to understand earthquake hazards and risk in earthquakeprone areas.

In this type of experiment, two rings of rock rotate past one another so that the relative displacement on the simulated fault surface can be very large. Also, this apparatus can be operated at high slip rates, simulating the actual rupture speed during an earthquake.

Rock Physics Labs USGS Earthquake Hazard Program

This unique earthquakegenerating machine is large enough to allow both nucleation and rupture propagation to occur on the fault surface. In this way, the slow earthquake initiation process can be studied in detail, as well as the way that the rupture propagates along the fault and ultimately stops.
