[3] Although the 1989 Loma Prieta earthquake was named for this mountain, the actual epicenter was five miles southwest of the peak, across the San Andreas Fault, in The Forest of Nisene Marks State Park.

In September 2005, it moved its transmitter 83 kilometres (52 mi) northwest to San Bruno Mountain after it became the Bay Area's NBC affiliate.

Loma Prieta and other nearby mountain peaks are pushed upward by local collision forces associated with a left bend in the San Andreas Fault.

Rather, the resulting transpression force pushes up the local terrain and helps explain why these are the highest peaks in the Santa Cruz Mountains.
