Yes, the Geysers area experienced many triggered earthquakes after the Landers event. In fact, since then seismologists have observed that activity in the Geysers area often picks up after large earthquakes elsewhere in California. One similarity between the volcanic center at Long Valley caldera and the Geysers area is that both have hot rocks. In fact, the Geysers area includes a geothermal power plant that turns the heat from these rocks into electricity. The heat in both areas may have something to do with why there are triggered earthquakes there.
The magnitude 7.3 Landers earthquake took place in the desert east of Los Angeles. The seismograms were recorded by the USGS's Northern California Seismic Network on instruments in Long Valley, Parkfield, and the Geysers.
