San Fernando Valley California Earthquakes of 1971 and 1994 |
This slide set compares two earthquakes that were separated by a distance of 10 miles and a time of 23 years. Disproving the notion that once an earthquake has occurred, an area is safe from future earthquakes, these events affected much of the same area and even some of the same structures. These two events were the largest of 17 moderate-sized main shock/aftershock sequences that have occurred in the Los Angeles area since 1920. The 1971 shock is referred to in the scientific literature as the San Fernando earthquake. The 1994 shock (also in the San Fernando Valley) is called the Northridge earthquake. This slide set compares the two earthquakes. The pictures show the same type of damage in some cases, and effects at the same site in other cases. |
