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 oblique reverse faults and were within of the M6.9 Loma Prieta mainshock epicenter, near the intersection of the San Andreas and Sargent faults. Total displacement for these shocks was relatively small (approximately of strike-slip and substantially less reverse-slip) and although they occurred on separate faults and well before the mainshock, a group of seismologists considered these to be foreshocks due to their location in space and time relative to the main event. Each event's aftershock sequence and effect on stress drop was closely examined, and their study indicated that the shocks affected the mainshock's rupture process. Following the August 8,
