Volcano 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 Control Panel. Clicking on an earthquake symbol shows its basic information and a link to a page with more details about the individual earthquake.
Control Panel
Volcano 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.

Mount Baker is an ice-clad volcano in the North Cascades, located about 50 kilometers E of Bellingham, WA. After Mount Rainier, it is the most heavily glaciated of the Cascade volcanoes.
Deposits which record the last 14,000 years at Mount Baker indicate that it has not had highly explosive eruptions like those of Mount St. Helens or Glacier Peak, nor has it erupted frequently. Historically, the most destructive and frequent events at Mount Baker have been debris flows and avalanches, some of which coincided with eruptive activity. Heat flow and fumarolic activity became elevated in 1975, but were not accompanied by any other changes.

Background Seismicity
The PNSN operates 2 seismometers on or near Mount Baker. On average, we locate 1 to 2 earthquakes within 10 km of the volcano each year. We also often record seismic events related to glacier motion, and less frequently those related to rock-fall or ice/snow avalanches.
