What type of fault caused the 1994 Northridge earthquake?

What type of fault caused the 1994 Northridge earthquake?

thrust faults
Northridge California Earthquake 1994 Summary The thrust faults along which the 1971, 1987, and 1994 earthquakes occurred are the result of a big bend in the San Andreas fault. The bend causes crumpling, or “compression” of the Earth’s crust nearby, giving rise to the thrust faults.

What were the effects of the 1994 Northridge earthquake in Los Angeles?

The 6.7 magnitude earthquake damaged several buildings as well as destroying all communications, such as telephone lines and causing computer systems to shut down. The seismic event killed two CSUN students at the Northridge Meadows Complex along with 14 other residents.

What process caused the greatest number of fatalities during the 1994 Northridge California earthquake?

Most of the fatalities were due to building collapse, and most of the hospital-admitted injuries were caused by falls or being hit by objects.

Is Los Angeles on the San Andreas Fault?

The San Andreas Fault is the sliding boundary between the Pacific Plate and the North American Plate. It slices California in two from Cape Mendocino to the Mexican border. San Diego, Los Angeles and Big Sur are on the Pacific Plate. San Francisco, Sacramento and the Sierra Nevada are on the North American Plate.

How was the Northridge earthquake caused?

A magnitude 6.7 quake caused by the sudden rupture of a previously undocumented blind thrust fault woke thousands of Angelenos, driving the City of Angels into a nightmarish frenzy. The nature of earthquakes is that they strike when least expected and during that brief ripple in time, life is at a standstill.

Will La break away from California?

No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates. There is nowhere for California to fall, however, Los Angeles and San Francisco will one day be adjacent to one another!

What was the cause of the 1994 Los Angeles earthquake?

The 1994 Los Angeles Earthquake happened when a blind thrust fault occured on an very populated area undergoing compressional stress that has rocks that deform in a ductile fashion overlying rocks that deform in a crumbly fashion. The compressional stress then causes the upper rocks to fold as…

Where was the epicenter of the Los Angeles earthquake?

The earthquake struck in the San Fernando Valley about 20 miles (32 km) northwest of downtown Los Angeles. Although given the name “Northridge”, where the quake was believed to have been centered and substantial damage occurred, the actual epicenter was pinpointed in the neighboring community of Reseda within several days.

Where was the epicenter of the 1994 Northridge earthquake?

Thousands of landslides occurred throughout the mountains surrounding the San Fernando Valley and as far north as Castaic Lake. Widespread liquefaction (saturated soil that behaves as a liquid when shaken) was triggered as far away as the Port of Los Angeles, some 30 miles from the epicenter.

How many people died in the Los Angeles earthquake?

People who inhale certain airborn spores get infected with the disease called coccidioidomycosis, 203 people caught this disease. 57 people died and over 8,500 were injured from collasping buildings, freeways collasping, ect.
