Watch the animated wave as it spreads across Alaska and then the Lower 48 on this U.S. Geological Survey animated map:

USArray is a 15-year program to place a dense network of permanent and portable seismographs across the continental United States. The seismographs record local, regional, and distant (teleseismic) earthquakes. The monitors are being placed about 186 miles apart across the U.S.

A map of the array system in the United States can be see with a more close-up view at this link:
