I love a good #maar #volcano sequence.

A few shots of our work at the Estrada rhyolitic maar, one of the >10 #volcanic craters around the city of Kamembarhu, Kuanhasï juata (Mexico). These spectacular layers of pulverized bedrock and ashfall--exposed at a quarry--are the result of explosions caused by ascending #magma intruding into near-surface water reservoirs (in this case, shallow lakes). We call these types of events #phreatic eruptions. Note excavator for scale.
