ANIMATION: THE QUAKE PICKED UP AS FAR AWAY AS SOUTH FLORIDA
A series of seismic monitors across the United States, as far away as Southern Florida, picked up vertical and/or horizontal motion in the minutes after the 7.1 magnitude earthquake struck Southcentral Alaska on Nov. 30.
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:
Another excellent example of fact gathering for us, Suzanne! I had no idea that monitors as far away as Florida picked up our Nov 30 quake.
Notice the activity coming up through the South from the wave that went over the Pole and around the earth…cool. The earth “rang like a bell” with the ’64 quake. As for now…. waiting impatiently for this one;s aftershocks to fade completely away.
