. . . Chile’s Calbuco volcano awoke from a four-decade-long sleep, starting a VEI 4 eruption at a moment when daylight was just right for some spectacular images.

In all likelihood, that wasn’t the world’s most recent subplinian eruption.

While no intensity rating is given for it on the Global Volcanism Program website, the Decade Volcano we’re going to meet this Sunday also had a powerful eruption — probably in the VEI 4 range — in 2019.
