Increased Seismicity When Superstorm Sandy Turned (image) University of Utah Share Print E-Mail Caption This map, taken from a University of Utah video, shows colored dots to represent the locations of portable seismometers in the Earthscope array, which is funded by the National Science Foundation. Most are now located in the eastern part of the United States. Blue-green dots indicate low seismic activity, while yellow-orange-red dots indicate stronger seismic activity. The map shows that when superstorm Sandy turned west-northwest toward Long Island, New York City and New Jersey on Oct. 29, 2012, the seismometers "lit up" because of ground shaking by certain ocean waves imparting energy to the seafloor.
