Mount Spurr Volcano in Alaska Shaking Like a Cold Wet Dog…

Just check out the recent seismicity:

It has had the most seismicity in the last four weeks of any Alaskan Volcano:

Mount Spurr volcano is an ice- and snow-covered stratovolcano located on the west side of Cook Inlet approximately 120 km (75 mi) west of
Anchorage. The only known historical eruptions occurred in 1953 and 1992 from the Crater Peak flank vent located 3.5 km (2 mi) south of the summit of
Mount Spurr. These eruptions were brief, explosive, and produced columns of ash that rose up to 20 km (65,000 ft) above sea level and deposited
several mm of ash in south-central Alaska, including approximately 6 mm of ash on Anchorage in 1953. The last known eruption from the summit of Mount
Spurr was more than 5,000 years ago. Primary hazards during future eruptions include far-traveled ash clouds, ash fall, pyroclastic flows, and
lahars….

Go to this link to see the interactive map and check on the left what you want to see. Spurr is the one at the very top, the most north:

And one of the webicorders showing seismicity:

As you can see from my posted pic at top, Anchorage is not all that far away, and I wonder to what degree it would be affected if Spurr were to erupt.

Seeing as Spurr is just north of Redoubt and Iliamna, I already have some goodies in place to monitor this explosive beast, so monitoring it I am. And
I got the number to call if it decides to blow in the middle of the night…

But even with all this seismicity, the color code remains green- so obviously the AVO feels like upgrading the alert level isn’t
necessary…yet.
