Map shows earthquake locations from the UUSS earthquake catalog as circles and locations from other networks as squares. Please note that earthquakes in areas outside of the two UUSS monitoring regions (black boxes) may be incomplete. See USGS for more complete earthquake information outside of the black boxes.

The sizes of symbols scale with earthquake magnitude, and their color with either the age of the earthquake or its depth, as shown in the legend below, and selected in the panel to the right of the map.  Clicking on an earthquake symbol shows its basic details and a link to a page with more details about the individual earthquake. Probable surface explosions (usually due to quarrying or road building) are shown as stars.
