Recent Eqs Map Legend

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.
