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), while not routinely located and displayed on this map, are shown as stars.

Recent Eqs Map Panel

Using the tools in this panel you can control the earthquakes shown on the map. The minimum magnitude to plot is selected by the slider. The "Time" and "Depth" determines whether earthquake age or depth are used to color the symbol.

 The red polygon is the reporting region for  this map; the black polygons are the authoritative regions of CERI (the NM network for the New Madrid region and the SE network for the southeast region). Events submitted by CERI are rendered as cirlces; events submitted by another network (e.g. the USGS NEIC) are rendered as squares. Explosions, while not routinely posted, are always rendered as stars.  .
