All volcanoes in California were at normal levels of activity last week. usgs.gov/programs/VHP/v… CalVO postdoc Genna Chiaro recently gathered rhyolite from the Mono Craters lava domes, near Long Valley, to track their ages & magma supply evolution.

Wanna know how old a volcanic rock is? Nuke it! Well, sort of... This week's #Yellowstone #CalderaChronicles explains the details of argon dating.

Resharing this week's #Yellowstone #CalderaChronicles , which might have been overlooked in the excitement of this week's Kīlauea eruption.

All about McDermitt Caldera -- the first in the line of calderas that stretches from northern NV / southern OR, across ID, to Yellowstone!

New satellite radar interferogram shows deformation that accompanied the June 3 Kīlauea eruption!

Data provided by Agenzia Spaziale ITA and indicate extension across the SW rift zone due to dike emplacement that fed the June 3 eruption.
