1989 Loma Prieta earthquake significant issue, especially in the heavily damaged Marina District of San Francisco, but its effects were also seen in the East Bay, and near the shore of Monterey Bay, where a non-destructive tsunami was also observed. Due to the sports coverage of the 1989 World Series, it became the first major earthquake in the United States that was broadcast live on national television (and is sometimes referred to as the "World Series earthquake" as a result). Rush-hour traffic on the Bay Area freeways was lighter than normal because the game was about to begin, and this may have prevented a
1989 Loma Prieta earthquake Beroza, a seismologist with Stanford University, made several distinctions regarding the 1906 and 1989 events. Near Loma Prieta, the 1906 rupture was more shallow, had more strike-slip, and occurred on a fault that was near vertical. The 1989 event's oblique-slip rupture was at 10 km and below on a fault plane that dipped 70° to the southwest. Because much of the slip in 1989 occurred at depth and the rupture propagated up dip, Beroza proposed that the overlying San Andreas Fault actually inhibited further rupture and also maintains that the occurrence of an event at the location that was forecast
