Lonquimay volcano (Central Chile) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 March-22 March 2022 (New Activity / Unrest)
SERNAGEOMIN reported increased seismicity at Lonquimay during the first half of March, characterized by hybrid (HB) signals accompanied by long-period (LP) events, and fewer volcano-tectonic (VT) events. Only some of the HB and VT events could be located where the epicenters were within 2-7 km of the volcano with hypocenters at depths of 4-11 km. The number of HB and VT events increased on 9 March.

Deformation was not detected and no abnormal gas emissions were recorded. During 18-21 March two additional earthquakes were recorded, a VT and an HB, both with magnitudes below 1.3. Although the events were low magnitude, the seismicity was anomalous in the data going back to 2010 when monitoring stations were installed.
The Alert Level was raised to Yellow, the second lowest level on a four-color scale.
