WebQuestion: 1)The 1989 Loma Prieta Earthquake a)Produced little damage because most of the areas affected were built on bedrock b)Destroyed freeways and buildings built on landfill c. Was produced by a normal fault d.Was produced by a reverse fault 2 )A _____ earthquake on the Richter scale can cause significant property damage. largest amplitude waves had passed. Eastbound drivers stuck on the lower deck between the collapse and Yerba Buena Island were routed up to the upper deck and westward back to San Francisco. Street-level Mandela Parkway now occupies the previous roadbed of the Cypress structure. Following the August 8, 1989 shock, in anticipation of an upcoming large earthquake, staff at the University of California, Santa Cruz deployed four accelerometers in the area, which were positioned at the UCSC campus, two residences in Santa Cruz, and a home in Los Gatos. In the magnitude 6.9 Loma Prieta earthquake of 1989, a brick wall in San Francisco fell onto a parking lot, leaving cars crushed; five people died. grassroots elite basketball ; why does ted lasso have a southern accent . ; What type of fault caused the loma preita earthquake? Also, during the 1989 Loma Prieta, California earthquake, liquefaction of the soils and debris used to fill in a lagoon caused major subsidence, fracturing, and horizontal sliding of the ground surface in the Marina district in San Francisco. Webarmenian population in los angeles 2020; cs2so4 ionic or covalent; duluth brewing and malting; 4 bedroom house for rent in rowville; tichina arnold and regina king related Having boasted a magnitude of 6.9, it is the biggest to hit the region in 34 The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately 10 mi (16 km) northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. In the 19th century, the peak was called Mount Bache, a name given in honor of Alexander Dallas Bache; the name is no longer in use.[4]. From the Archives: ABC7's Peabody Award winning coverage of 1989 Loma Prieta The October 18, 1989, edition of NBC's Today that covered the earthquake ran until noon Eastern Time. Bar none! Local History. 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. [58] Santa Cruz beach lifeguards assisted in moving the victims. [60] The body of a young woman coffee worker was found under a collapsed wall late the next day. Forty-two people were crushed to death in their cars. [57], Immediately, a number of civilians began to free victims from the rubble of Ford's Department Store and the Santa Cruz Coffee Roasting Company both buildings had collapsed inward on customers and employees alike. Because it happened during a national live broadcast of the 1989 World Series, the annual championship series of Major League Baseball, taking place between Bay Area teams San Francisco Giants and the Oakland Athletics, it is sometimes referred to as the "World Series earthquake", with the championship games of the year being referred to as the "Earthquake Series". WebCompares the 1989 loma prieta earthquake to the 1906 earthquake, which destroyed most of san francisco and its buildings. No state legislature to ensure that every building is resistant. [35] Some 31 buildings were damaged enough to warrant demolition, seven of which had been listed in the Santa Cruz Historic Building Survey. 0000001519 00000 n 0000001412 00000 n At what magnitude does damage begin to occur in an earthquake? Andrew Lawson, a geologist from the University of California, Berkeley, had named the fault after the San Andreas Lake (prior to the occurrence of the 1906 San Francisco earthquake) and later led an investigation into that event. At more than 44 miles (70km) distant, the San Francisco Bay Area recorded peak horizontal accelerations that were as high as 0.26 g, and close to the epicenter they peaked at more than 0.6 g. 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 (40km) in length. [8][13], The ML 5.3 June 1988 and the ML 5.4 August 1989 events also occurred on previously unknown oblique reverse faults and were within 3mi (4.8km) of the M6.9 Loma Prieta mainshock epicenter, near the intersection of the San Andreas and Sargent faults. Experts are tested by Chegg as specialists in their subject area. ", "Putting Down Roots in Earthquake Country", "Buildings Demolished in Downtown Santa Cruz as a result of the Loma Prieta Earthquake, 1989". Liquefaction probability curves that predict the probability of surface manifestations of earthquake-induced liquefaction are developed for 14 different types of surficial geologic units. The Loma Prieta earthquake caused a great deal of destruction in San Francisco, amassing to about $6 billion in damage repair. Loma Prieta is the tallest peak in the Santa Cruz Mountains and it is common to see snow on the mountain during the winter. [16], The contrasting characteristics of the 1906 and 1989 events were examined by seismologists Hiroo Kanamori and Kenji Satake. a.
