Revival of Misti volcano, located near Arequipa in Peru, a very populated area.

The OVS reports that the volcano crater images, taken four weeks ago, shows the existence of fumaroles, indicating a possible next eruption. Scientists confirm that the gases released by the Misti are" magmatic and contain sulfuric acid, carbon and calcium."

The gases are dissipated by winds and do not affect the people.

Note that the entire city of Arequipa is vulnerable to pyroclastic surges, and areas closest to the volcano would be at high risk even for small- and medium-sized events.

The battle between erosion and power may turn quickly in favor of the first.
