Which earthquake center is linked with the 6.9 magnitude event known as Loma Prieta?

The event known as the Loma Prieta earthquake, which occurred on October 17, 1989, is indeed linked with the Elysian Park earthquake center. The Loma Prieta earthquake was centered near Loma Prieta Peak in the Santa Cruz Mountains, and it had a moment magnitude of 6.9. The seismic events referenced in the other choices—Coalinga, Landers, and Northridge—occurred at different times and locations in California and are associated with separate significant earthquakes.

The Northridge earthquake occurred later, on January 17, 1994, and had a magnitude of 6.7. While it was a substantial incident, it is distinct from the Loma Prieta event in both location and timing. Therefore, Elysian Park is the correct link for the Loma Prieta earthquake, reflecting the importance of identifying earthquake epicenters and their corresponding seismic activity in California's geological history. Understanding these differences is crucial for recognizing the various seismic hazards and landscape dynamics across the state.
