Overview
- Volcanic tremor began at 7:42 pm local time on January 18, with eruptive fissures opening on the north flank inside the Enclos Fouqué.
- Officials reported the activity confined to an uninhabited zone with no particular threat to people or infrastructure outside the caldera.
- Crowds surged to viewing areas despite closures, with the prefecture estimating about 3,500 vehicles on Monday and issuing more than 50 tickets for illegal parking.
- Observations varied from three to four fissures and lava fountains reaching 10 to 20 meters, tapering to a single active vent by Monday afternoon.
- Volcanologists continue close monitoring and do not rule out a possible resumption given ongoing seismicity, following weeks of precursory quakes including a strong episode on December 31–January 1.
