Laboratory Earthquakes: Direct Observation of Stick-Slip Fault Behavior
Laboratory seismology uses a scale-model approach to complement the wealth of research on in situ earthquakes that cannot be observed directly. A simple mechanical system applies shear stress to two blocks with a roughened interface, such that it produces stick-slip behavior with energy signatures matching in situ earthquakes. Lab scale seismic sensors allow us to apply typical seismological analyses. Additional instruments provide measurements not available in the field, which are used to expand our understanding of the underlying processes as well as the results and limits of the seismological methods.
