northridge earthquake 1994 damage

The waves can be trapped along the edges of the basins, or reflected so that they travel as surface waves across the basins. The earthquake was felt over more than 200,000 square kilometers of the land area of the United States and Mexico and at distances of 400 kilometers from the epicenter. And, that was only the beginning. In addition, the campus received a $23,000 check (equivalent to $40,000 today) from the FM radio stations such as KRTH, KIIS-FM, KOST-FM and KCBS-FM were bringing special reports when morning show hosts In the weeks following the quake, many San Fernando Valley residents had either lost their homes entirely or experienced structural damage too severe to continue living in them without making repairs.

("red-tagged") after the Northridge Earthquake of Jan. 17, 1994. Post-1940 single-family dwellings constituted both the largest building category and the strongest in terms of resistance to damage. Source: FEMA/Wikipedia Affecting much of southern California, the Northridge, California, earthquake of January 17, 1994 was the costliest earthquake in U.S. history in …
The USGS and Caltech have substantially improved seismic recording and reporting in southern California, and are now using the system for many applications beyond research.

The earthquake deformed the Earth's crust over an area of 4,000 square kilometers, forcing the land surface upward in the shape of an asymmetric dome.

Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree....

At 4:30 am, on January 17, 1994, residents of the greater Los Angeles area were rudely awakened by the strong shaking of the Northridge earthquake. When the dam was tested by the Northridge earthquake, it showed only minor deformation and superficial cracking compared to its predecessor that nearly failed catastrophically in 1971. Scientists were also able to validate the practice of using data from small aftershocks to predict local site responses to strong ground motions. This was the first earthquake to strike directly under an urban area of the United States since the 1933 Long Beach earthquake. Post-1940 multi-family dwellings proved to be more susceptible to shaking damages than masonry buildings or pre-1940 single-family and 2-to-4-family wood-frame dwellings.

Although the vast majority of homes in the area, with the exception of a few particular neighborhoods, were relatively unaffected; many feared an While many businesses remained closed in the days following the quake, some infrastructure was not able to be rebuilt for months, even years later. Notably, the system can now be used for estimating the extent of damage from an earthquake within a few minutes of detection of shaking, and reporting this information to all public and private organizations that engage in rapid response. Systems of concealed faults under the Los Angeles area are more complex than previously thought.
