1. There is NOT enough erupt-able magma in the chamber to facilitate an eruption.
2. Besides that..there have been several eruptions in its history comparable to Mount St Helens...I.E. the west thumb of the lake.
3. The USGS ratings of the likely hood of eruption is not even on the radar for it comparable to the Long Valley caldera-that one is the highest in the continental USA. All the volcanoes on the Cascade and Sierra Ranges are high.
Yellowstone does not even register.
End of story.
