Overview
- The flow entered the Indian Ocean at about 00:20 on March 16, generating large vapor and gas plumes at the coastal cliff.
- Three lava arms crossed the RN2 between Sainte-Rose and Saint-Philippe and nearly merged, covering roughly 250 meters of roadway.
- The volcanological observatory says the ocean entry is ongoing and secondary arms are advancing toward the RN2, with one about 2.1 km from the road at midday Monday.
- Authorities cite sulfur dioxide and suspended particles from lava–seawater reactions, issue fines for illegal parking, and reported evacuating about 50 people due to poor air.
- The eruption, active since February 13 after a January episode, features low seismicity and an uncertain duration, according to OVPF.
