DID YOU FEEL IT?!
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. Follow the link above, then click on the orange “Report Unknown Event” tab and fill in the blanks. Hopefully, we won’t be entering data on this site, but it also has a lot of earthquake info, including historical events and how to be prepared for the big one!
