Since the early 1990s, the magnitude and location of an earthquake have been
available within minutes on the Internet. Now, as a result of work by the
U.S. Geological Survey and with the cooperation of various regional seismic
networks, people who experience an earthquake can go online and share information
about its effects to help create a map of shaking intensities and damage.
Such “Community Internet Intensity Maps” (CIIMs) contribute greatly toward
the quick assessment of the scope of an earthquake emergency and provide
valuable data for earthquake research.
