October 17, 1989 (Part 3)

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. In Part 3 (of 4-part series), scientists discuss what impact the Loma Prieta earthquake had on seismic research, what they learned from experiencing it firsthand, and how society responded with emergency preparedness to the threat of future earthquakes.
