Erupting Volcanoes

QuakeFeed Premium feature! When this map layer is turned on, volcanoes that are currently erupting will be displayed on the map as red triangles.

Plate Lines and Faults

Turn this switch On if you would like to see tectonic plate lines and faults (Western US and Alaska only) displayed on the map.

Symbol Style

Choose whether to symbolize the earthquakes with markers or circles.
