northridge earthquake 1987 magnitude
Look back at KNBCʼs coverage of the the 1994 Northridge earthquake. Buildings crumbled in the 1994 Northridge earthquake, rated the most expensive in U.S. history. In the case of the Northridge … 2. The Northridge earthquake occurred on January 17, 1994 at 4:30am,the quake was caused by the sudden rupture of a previously undocumented blind thrust fault, it hit a magnitude of 6.7, the earthquake was so strong parts of Los Angeles area, Ventura area, Las Vegas, and San Diego felt the shake of the earthquake, there were many fatalities about 60 deaths, and 2000 injuries. One ©f many So southern Calif©rnna.- The 1971 San Fernando, 1987 Whittier Narrows, and 1994 Northridge earthquakes are all magnitude 6.0 (or greater) shocks that lie within 25 miles of each other. It began at 4:31 a.m. on January 17, 1994. As anyone who lives in Southern California knows, the Northridge quake was sizable. Its epicentre was in Northridge, a suburb located about 20 miles (32 km) west-northwest of downtown Los Angeles.The major shock lasted 10–20 seconds and registered a magnitude of 6.7. October 17, 1989: $10 billion. The 1994 Northridge earthquake was a moment magnitude 6.7 (M w), blind thrust earthquake that occurred on the annual Martin Luther King, Jr. Day holiday, on Monday, January 17, 1994. On January 17, 1994, at 4:31 a.m. PST, a magnitude 6 .7 earthquake centered in Northridge struck the southern California area. With a moment magnitude of 6.7, the Northridge earthquake was the strongest earthquake to strike the Los Angeles area since the 1971 San Fernando earthquake, which also had a magnitude of 6.7. Northridge California Earthquake 1994 Summary The Northridge Earthquake. The 6.8 magnitude Northridge earthquake was blamed for some 60 deaths, thousands of injuries and billions in property damage. Known as the Northridge Earthquake, it caused at least 57 fatalities (a subsequent study put the death toll at 72, including heart attacks) and injured thousands. Are they related? It … earthquake alerted federal and state governments, as well as private insurers to the magnitude of potential losses from earthquakes in urban areas. The earthquake in Northridge, Los Angeles County, had a moment magnitude (or total energy release) of 6.7 (moderate magnitude). The earthquake occurred just after 4:30 am local time along a previously undiscovered blind thrust fault in the San Fernando Valley. The earthquake occurred beneath Northridge, a suburb in the San Fernando Valley, 30 km northwest of Los Angeles (see map on next page). Graves compared the possible damage the Puente Hills fault was able to cause to the 1994 magnitude-6.7 Northridge earthquake. But nowhere was the destructive power of nature more evident than in the collapsed sections of four major freeways, including the nation's busiest, Interstate 10, and California's lifeline of commerce, Interstate 5. With a magnitude of 6.7, and an untoward power on other fronts that only seismologists understand, it remains one of the two most destructive quakes in recent memory (the other being the 5.9 Whittier Narrows quake in 1987). 1.2 Detailed Description of Earthquake The Northridge earthquake occurred on an unknown ’blind thrust’, meaning that the rupture never spread to the earth’s surface, but stopped some way below it.
