Monitoring & Webcams

The broad band seismometer SHUK rests in a covered container on the east flank of Mount Baker. Click to enlarge.

Mount Baker Monitoring 

Today’s eruption simulation from USGS. A computer model based on actual wind direction and strength, updated twice daily. Measured ash thickness from past Baker eruptions are used to calculate ash dispersal and ash thickness from a large eruption occurring at 10 AM and 10 PM.

Mount Baker seismic activity is collected at two seismic stations, one to the west (MBW) and one on the east (SHUK). To see maps of locations and magnitudes:

  • Pacific Northwest Seismic Network (University of Washington). Includes map with epicenters of the 20 most recent earthquakes in the Mount Baker area. NOTE: the map at the PNSN site showing Baker earthquakes is very small. Zoom in and look carefully for the tiny icons used to mark epicenters. PNSN also posts a summary of seismic activity at all the Cascade stratovolcanoes.
  • 24-hour Webicorder seismometer data (charts) for Cascade volcanoes from Pacific Northwest Seismic Network. Scroll down to find current data for MBW (Mount Baker West) and SHUK (Shuksan Arm). Click on each for that station’s data. The page on “how to read the webicorder data” has been taken down.
  • Geochemical monitoring Go to this page to read about fumarole sampling in Sherman Crater, why and how it is done, and where to see the data.

  3. I look at mount Baker a lot and have noticed a big change in the mountains appearance. Like the peak is not as a shape point and the left side seems to be bulging out. I am not the only one that has noticed this. Just wondering.

    • Melissa,
      I can see no changes to the shape of Mount Baker. A pilot friend flew around it today and reported ‘all is normal’. It does pay to keep an eye on that mountain, though.

  4. I heard a large boom and the house shook this morning around 7:30am – was it seismic?

    • Carl- where are you located. See the listing of recent earthquakes on the left column at the Pacific Northwest Seismic Network: No major seismic activity reported in the area. Dave Tucker

  5. This is way late, but while hiking on the Heliotrope trail, our group smelled a very strong odor of sulfur. Coordinates: 48.800099° -121.889125°. Probably just a matter of air currents, but that was the first whiff of sulfur after many trips on the trail.

    • Thanks for the report. That is unusual, but almost certainly related to weird wind eddies from Sherman Crater, or just as likely from Dorr Fumaroles on the NE side of Baker. No other known sulphur fumes sources up there. Dave
