Caldera chronicles: Scientists refine strategy for responding to geological events

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from Scott Johnson, science communications associate for UNAVCO.

The morning of May 11 was notable for a magnitude 4.2 earthquake 23 miles northeast of Yellowstone’s East Entrance, which was the largest quake in the park since 2017. But it was also notable for another reason — members of the Yellowstone Volcano Observatory consortium happened to be gathering in the park at the Mammoth Hot Springs Hotel for a simulation to practice responding to a hypothetical geological event.

It was the first in-person meeting for YVO since 2018, and fortunately there were no additional real-world events after the magnitude 4.2 to disrupt the agenda. It was a great opportunity for the group to share some of their science, talk with National Park Service staff, and brainstorm new research and outreach efforts.

The “tabletop” exercise at the heart of the meeting was led by Jessica Ball of the California Volcano Observatory and John Ewert of the Cascades Volcano Observatory and Volcano Disaster Assistance Program (that’s the USGS international volcano response team).
