Overview
- Argentina’s SEGEMAR/OAVV logged a pulse of gas and ash at 09:58 local time on November 6 that rose about 1,100 meters above the crater.
- The column dispersed toward the south-southeast, following hours of minor gas-and-ash emissions seen on cameras overnight.
- Monitoring networks noted a punctual increase in tremor between 20:30 and 21:30 the night before, consistent with fluid and gas movement in the system.
- The technical alert has stayed at yellow since July and real-time seismic and visual surveillance continues.
- Authorities warn additional low-to-moderate explosions are possible and are coordinating closely with Chile’s OVDAS.
