Pyroclastic flows from Sinabung


This article has some spectacular pictures of the ongoing eruption of Mt. Sinabung:

What it looks like when a volcano erupts 77 times in a single day

The image below is from the article, and shows the classic signature of a pyroclastic flow -- aka the "glowing avalanche" or nuee ardente

















Compare that picture to these historical pictures of the eruption of Mont Pelee on the island of Martinique in the Caribbean, which laid waste to the entire city of St. Pierre with a full-scale nuee ardente



These are the bad boys of the volcano world.  Let's hope Sinabung doesn't unleash a monster.
