The first plot (top) shows over 600 of the best-located earthquakes (red circles) in north-central New Mexico during the 19 years from 1973 through 2001. The size of each circle is proportional to the magnitude of the earthquakes (filled circles at bottom right show magnitudes from 0 to 3). Faults are drawn in black, rivers in blue, major roads in green. Stations are shown as triangles- those currently operating as blue upright triangles.

The second plot (bottom) shows an expanded view of earthquakes in the immediate Los Alamos area updated through 2007.
