Poas Volcano Eruption Update; Largest Eruption in 53 Years, Ash Falls on Capital

Описание: The Poas volcano just produced its largest explosive eruption in 53 years, causing ash to rain down on many nearby communities including to a lighter extent the capital city of Costa Rica, San Jose. This occurred after a 10 day long drop in activity, in which I interpret a volcanic plug had formed and was blocking building pressure and gas at depth. Today's video will discuss the model of the eruption I have created, what exactly happened, and discusses what might happen next through the analysis of a geologist.

Note: The thumbnail image for today's video shows a 2018 eruption photo of Kilauea rather than Poas. I am using it as a stand-in image for Poas in an attempt to portray what its initial eruption plume close up might have looked like.
