The fault exhibits a diversity of slip behaviors including large coseismic rupture, frequent micro-seismicity, and aseismic creep.

They represent the release of strain on the plate interface, similar to what occurs in traditional earthquakes. However, slow slip events last for days or weeks, whereas a traditional earthquake lasts on the order of seconds. The slow nature of these events means that no seismic waves are generated, and therefore the events are inconspicuous to the general public even thou…
