The Servicio Geológico Minero Argentino (SEGEMAR) reported that ash-eruptive pulses took place from the volcano’s summit vent yesterday.
Near-constant ash plumes, detected at 10:56 and 13:01 local time, continued from the crater characterized as „only“ venting or passive emissions of small to moderate ash. Ash columns rose 300 meters above the crater and drifted northeast.
The seismic network registered a long-period (low-frequency) earthquake associated with events.
The Volcanic Alert Level remains at Yellow with 500 meters exclusion zone around the main crater in place.
