Tungurahua volcano (Ecuador): explosions generate small pyroclastic flows

A series of small pyroclastic flows occurred yesterday evening, IGEPN reported in its latest special bulletin.

The eruptions took place between 18:23 and 19:00 local time, and are the first occurrences of pyroclastic flows since the start of the new eruptive phase that started on 27 July.
Fortunately, the flows were small and eruptive activity remains only moderate, as frequent but typically smaller explosions occur and release pressure. It is thought that the volcano is currently in a state of having an open conduit, allowing magma to rise easily to the crater before building up large pressure.
IGPEN mentioned that significant deformation of the upper part of the volcano had been detected recently, indicating that more magma is on its way towards the crater. Hence, similar eruptions are expected to continue for a while.

Activity continued to increase at the volcano as new magma continues to arrive at its summit. Since the first ash emission a week ago, more and stronger explosions, as well as phases of continuous ash and gas emissions and milder strombolian activity have occurred. ... read all

Activity of the volcano remains comparably low, with only few and weak emissions of low energy. A number of lahars, caused by heavy rains remobilizing loose deposits, occurred in the riverbeds of Ingapirca, La Rea, Achupashal and others streams on the S and SW sides. ... read all
