On October 17, 1989, at 5:04 pm a magnitude M6.9 earthquake struck near Loma Prieta, California. It was a tragic reminder of the destructive power of earthquakes. However, it was also a watershed moment in seismic research. 30 years later, we revisit the earthquake through the eyes of the scientists who experienced it. And studied it. These are their stories.

Retired seismologist David Oppenheimer reflects on the first prototype earthquake early warning system used during the 1989 Loma Prieta earthquake. Scientists deployed an analog system to notify first responders of impending earthquake activity as they worked on rescue efforts at the Cypress Viaduct collapse in Oakland, CA.

This video presents an animation of computer-simulated ground motions that might occur for a magnitude 6.9 earthquake rupturing the Rose Canyon fault in southern California. The scenario earthquake ruptures a 65-km-long section of the Rose Canyon fault that lies just offshore of San Diego, California, and Tijuana, Mexico.
