![]() So the information on this site records events in the last year, or last decade, rather than the last week. Because plate movement is fairly slow, the data are recorded over long periods of time. By taking advantage of the vast number of Internet users, we can get a more complete description of what people experienced, the effects of an earthquake, and the extent of damage. USGS keeps many stations that track movements of the earth's The Did You Feel It (DYFI) system was developed to tap the abundant information available about earthquakes from the people who experience them. USGS Global Positioning System (GPS) monitors This can be compared with other shake maps for the same quake that were generated from seismometer data. Seismometers can measure shaking, but how much does that reflect what people actually feel? On this site, people in the area of a quake can report their experiences to the USGS, and the results are made into a map. You can click the small boxes to zoom in and get more details on specific quakes. These maps are nice illustrations of the fact that earthquakes occur along faults.

Geological Survey 'Did You Feel It' Web site. The site also includes information on interpreting seismograms and examples of different magnitudes. When you have felt a quake, please report your observations by using a quick survey found on the U.S. ![]() ![]() Recorded by stations in the Northern California Seismic Network, these seismograms update every 5 minutes. IRIS (Incorporated Research Institutions for Seismology) has developed their Seismic Monitor that offers data about quake in near realtime, lets you search the Web for information about them, and view seismograms. The epicenter of the earthquake was in the vicinity of Magic Mountain, about six miles northeast of Sylmar, at a depth of about. On Februat 6:01 am PST, a devastating M6.6 earthquake struck the densely populated metropolitan area of Los Angeles, leaving death and destruction in its wake. Zooming in to a specific quake, you reach a page with specific data and links to the area's seimic and quake damage history. Source: California Integrated Seismic Network.

This section lets visitors see quakes that have occurred anywhere in the world in the last week. The USGS has many maps of live earthquake data.
