According to the Seismic Research Centre, a low thermal anomaly, indicating temperatures above normal levels, was detected at the summit of the volcano by NASA’s FIRMS hot spot detection system on 6 October. The heat anomaly is currently ongoing.
Potential explanations for this detection include a sulfur fire in the crater, a small phreatic (steam) eruption that may have exposed hot rocks, or the beginning of new lava extrusion within the crater. The National Emergency Management Organisation’s (NEMO) Soufrière Monitoring Team is currently analyzing multigas data collected on 4 October, with further investigations, including a sea-based reconnaissance along the West Coast, still underway. Additional updates will follow once the analysis of this data and visual observations are complete.
Despite the anomaly, the volcano’s status remains at the Green, meaning it is quiet, and both seismic and fumarolic (steam vent) activities are within normal historical levels. No other unusual activity has been observed.
