It was fire that destroyed most of San Francisco after the Big 1906 quake, and more than 110 fires destroyed blocks of buildings following the Northridge quake. Fire following a quake like that could bolt not only through Hollywood itself, but the neighboring Hollywood HIlls. The USGS is worried that a major quake in Hollywood would kill or injure more than a11,000 people, cause more than $20 billion in damage, and literally destroy the Hollywood area. Hollywood has been at the center of a battle over the construction of new buildings close to fault lines. We’re learning more about new and potentially deadly faults all the time. The San Andreas fault could shake Los Angeles for more than four minutes. This means that when the Seattle fault ruptures the south side of the fault moves up relative to the north side. The Northridge quake lasted approximately seven seconds, although the ground rocked and rolled for approximately 20 seconds. The San Andreas fault in California is a. It may be catastrophically larger than Northridge. What amazes us at MySafe:LA is the wealth of information available from that quake, and the lack of interest by many in Southern California. Rockwell said he expected the next one to be larger because it will have been at least 300 years since the last quake, with one side of the fault potentially moving. A freeway overpass on the Santa Monica Freeway collapsed more than 20 miles from the epicenter. The last big earthquake in this area on the San Andreas caused one part of the fault to move past the other by 12 to 14 feet, making it a likely magnitude 7.3 or 7.4 earthquake. The Northridge quake wasn’t a particularly large quake on the magnitude scale – a 6.7 magnitude, but it was one of the most destructive local quakes ever recorded in North America. The Northridge fault pushed up – a blind thrust fault called the Pico fault. When the San Andreas next rips, it will shift the ground side to side – a slip fault. Although centered in Reseda, the “Northridge” quake as it is known, killed 57 people, sent 1,600 to area hospitals, and injured more than 8,700.įrom a scientific perspective, this was an interesting quake, and quite different from the one most eyes are trained on: the San Andreas. At 4:31 on the 17th of January in 1994, a significant earthquake ripped through the San Fernando Valley, northwest of downtown Los Angeles. Never was a solemn solitude turned into teeming life quicker.This week, Los Angeles is buzzing with memories of the 1994 Northridge earthquake.

What Will Happen If San Andreas Fault Breaks A Newsweek report specified, the effect of the 'northern big one' would be tremendous. The new odds mean a large quake on the Garlock fault is now calculated to be 100 times more likely rising from 0.023 in the next year to 2.3. Never was a solemn solitude turned into teeming life quicker.” “Every door, of every house, as far as the eye could reach, was vomiting a stream of human beings and almost before one could execute a wink and begin another, there was a massed multitude of people stretching in endless procession down every street my position commanded. The San Andreas fault exists along the transform plate boundary between the Pacific and North America Plates in California. The streetcar had stopped, the horses were rearing and plunging, the passengers were pouring out at both ends, and one fat man had crashed halfway through a glass window on one side of the car, got wedged fast, and was squirming and screaming like an impaled madman. SAN ANDREAS Pacific EXPLANATION ALAMEDA Counties San Jose Cities and. “And here came the buggy-overboard went the man, and in less time than I can tell it the vehicle was distributed in small fragments along three hundred yards of street. quake probability 6.9 1950 1989 2000 1950 5.6 5.7 6.2 1984 5.8 5.7 1980 1979 1969 1969. Mark Twain later recounted a harrowing scene: Several successive earthquakes jockeyed for prominence when it came to the phrase “San Francisco earthquake” before 1906, including this now-obscure 19th century tremblor.
