The record section below shows seismograms recorded
on seismographic stations
spanning the contiguous United States.
The seismograms are plotted as a function of distance
with stations close to the earthquake at the top and
more distant stations plotted at the bottom.
Zero time corresponds to the origin time of the earthquake.
The station name is plotted to the right.
For large earthquakes, you can see several seismic arrivals
that travel different paths through the earth.
Each trace is normalized to its maximum amplitude.
