Progress toward a safer future since the 1989 Loma Prieta earthquake; 1999; FS; 151-99; Page, Robert A.; Stauffer, Peter H.; Hendley, James W., II However, it was also a watershed moment in seismic research. The thirty year probability for one or more M7 earthquakes in the study area was given as 50%, but because of a lack of information and low confidence, a 30% probability was assigned to the Southern Santa Cruz Mountains segment. Two moderate shocks, referred to as the The June 27, 1988, shock occurred with a maximum intensity of VI (The contrasting characteristics of the 1906 and 1989 events were examined by seismologists Fifty-seven of the deaths were directly caused by the earthquake; six further fatalities were ruled to have been caused indirectly.After the earthquake occurred, a group led by Antony C. Fraser-Smith of The earthquake caused severe damage in some very specific locations in the Bay Area, most notably on unstable soil in San Francisco and An estimated 1.4 million people lost power following the quake, mainly due to damaged Power was restored to most of San Francisco by midnight, and all but 12,000 customers had their power restored within two days.Four people died in San Francisco's Marina District, four buildings were destroyed by fire, and seven buildings collapsed. %PDF-1.4 %����

30 years later, we revisit the earthquake through the eyes of the scientists who experienced it. LOMA PRIETA EARTHQUAKE April 2006 The Loma Prieta earthquake registered magnitude 6.9. Not only did the quake force The 1989 World Series featured the Oakland Athletics and the San Francisco Giants in the first The network put up a green ABC Sports “World Series” technical difficulties Inside Candlestick Park, fewer than half of the more than 62,000 fansThe World Series was delayed while the Bay Area started the recovery process. 42 people were crushed to death in their cars.

The shaking lasted 15 seconds. Looking for a different adventure? The epicenter of the earthquake was at 37.036N 121.883W with the hypocenter 19 km below that. -Robert Page, U.S. Geological SurveyBelow are publications associated with this project.The purpose of this report is to provide a compilation of structural retrofits and replacements of older buildings and infrastructure in the San Francisco Bay Area that have either been completed since 1989 or that are in progress as of October 2018. 125 0 obj <> endobj And studied it.

This is the approximate location of the epicenter of the Loma Prieta Earthquake. This earthquake occurred October 17, 1989 - 5:04 pm local time and had a local magnitude of 6.9 and a surface-wave magnitude of 7.1. 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. The quake had a duration of approximately 10–20 seconds, and its peak ground acceleration of 1.82 g 0 (17.8 m/s 2) was the highest ever instrumentally recorded in an urban area in North America. 0000009723 00000 n
0000003451 00000 n However, it was also a watershed moment in seismic research. The epicenter was located near Loma Prieta peak in the Santa Cruz Mountains, approximately 14 km (9 mi) northeast of Santa Cruz and 96 km (60 mi) south-southeast of San Francisco. Not only the epicentric area was damaged. It examines how the fault that generated the earthquake ruptured, searches for and evaluates precursors that may have indicated an earthquake was coming, reviews forecasts of the earthquake, and describes the geology of the earthquake area and the crustal forces...Professional Paper 1553 describes how people and organizations responded to the earthquake and how the earthquake impacted people and society.
