Northridge Earthquake




What i learned from the Northridge Earthquake is that it ruuined most of the city and it killed many people and they still didnt know where most of the people were. They were still looking for the bodies and many families were crying and giving up because they knew they weren't going to be found.

Northridge earthquakes



The Northridge earthquake occurred at 4:30 a.m. local time on January 17, 1994. Northridge is located about 30 km northwest of Los Angeles. This earthquake had a 6.9 moment magnitude. The hypocentral depth was 19 km. The duration was about 10 seconds to 20 seconds. The earthquake occurred along a "blind" thrust fault, close to the San Andreas fault. Note that a blind fault is a fault which does not extend to the surface. In other words, it is buried.
