[79] Amtrak intercity rail service into Oakland from the California Zephyr continued, but the Coast Starlight was temporarily suspended north of Salinas because of damage to the Southern Pacific's Coast Line. After ten days (the longest delay in World Series history), Game 3 was held in San Francisco on October 27 and Game 4 the following afternoon as the A's swept the Giants, four games to none. The driver, Anamafi Moala, died, and the passenger, her brother, was seriously injured. This solution is similar to those obtained from long‐period Rayleigh and Love waves, P nL waves, and first‐motion data. [67] Employees from Pacific Pipe drove heavy lift equipment to the scene and started using it to raise sections of fallen freeway enough to allow further rescue. 6.9. Cars on the upper deck were tossed around violently, some of them flipped sideways and some of them were left dangling at the edge of the freeway. [95] There had also been a seismic-strengthening project previously completed on the upper deck concrete windscreen that may have prevented large numbers of injuries in the event of serious damage or even a catastrophic collapse. Describe how these two events are different in regards to the human impact. In a general way, the location of aftershocks of the event delineated the extent of the faulting, which (according to seismologist Bruce Bolt) extended about 24 miles (40 km) in length. Oakland Airport repair costs were assessed at $30 million (equivalent to $65 million today). The majority of landslides occurred to the southwest of the epicenter, especially along road cuts in the Santa Cruz Mountains and in the Summit Road area, but also along the bluffs of the Pacific Coast, and as far north as the Marin Peninsula. What are the names of the two plates? [37] There were structural failures of twin bridges across Struve Slough near Watsonville. On October 17, 1989, at 5:04:15 p.m. (PDT), a magnitude 6.9 earthquake severely shook the San Francisco and Monterey Bay regions. When the quake struck at approximately 5:04 PDT, sportscaster Tim McCarver was narrating taped highlights of Game 2, which had been played two days prior across the Bay Bridge in Oakland. We use a 3-D boundary-element algorithm to calculate static stresses, combined with a Coulomb failure criterion to calculate conjugate failure planes at aftershock locations. [59] The body of a young woman coffee worker was found under a collapsed wall late the next day. A miscommunication made by emergency workers at Yerba Buena Island routed some drivers the wrong way; they were directed to the upper deck where they drove eastward toward the collapse site. [62], When the earthquake struck, the freeway buckled and twisted before the support columns failed and the upper deck fell on the lower deck. prieta break out. 1989 Loma Prieta in San Francisco, California. The epicenter was located near Loma Prieta peak in the Santa Cruz Mountains, approximately 14 km (9 mi) northeast of Santa … c) If subduction of one plate occurred, then list the name of the plate that was subducted. The Loma Prieta earthquake is the latest in a series of destructive earthquakes that have rocked the San Francisco Bay area during historic times (Table 1). For the USA Loma Prieta Earthquake of 1989. :) 3.0 / 5. [57] Santa Cruz beach lifeguards assisted in moving the victims. We test the hypothesis that the origin of the diverse suite of aftershock mechanisms following the 1989 M 7.1 Loma Prieta, California, earthquake is related to the post-main-shock static stress field. The duration of a typical M6.9 shock with a comparable rupture length would have been about twice as long. [57] Police dogs were brought in to help locate other victims.
