Overview of Reventador infrasound activity: from January 2015 to June 2019

Abstract:

We present infrasound observations of a multi-year dataset recorded at Volcán El Reventador, Ecuador with the aim of studying volcanic and non-volcanic events and providing key parameters that relate to surficial processes. Reventador, monitored by Instituto Geofísico, is one of the most active volcanoes in the world exhibiting frequent explosive eruptions and episodic lava flows. Since 2015, we have progressively installed 3 infrasound arrays within 4 km of the summit, as infrasonic phenomena is one of the most predominant manifestations of activity at Reventador. The arrays have recorded multiple volcanic processes, including rockfalls, pyroclastic density currents, multiple vents, lateral eruptions, flank collapses and non-volcanic processes such as waterfalls, thunder, earthquakes, and echoes. Here, we present a broad overview of source locations, trends, and statistics for volcanic and non-volcanic events …
