NASA’s Fire Information for Resource Management System continues to detect thermal anomalies at the summit of the La Soufrière Volcano. (NASA)
|Present La Soufrière Alert Level:||ORANGE||There is a highly elevated level of seismic and/or fumarolic activity or other unusual activity. An eruption may begin with less than twenty-four hours’ notice.|
According to the latest scientific advisory from the University of the West Indies Seismic Research Centre (UWI SRC), thermal anomalies continue to be detected by the NASA FIRMS alert system. Thermal anomalies do not indicate an explosive event is imminent but that there is a source of heat, most likely from a small body of magma left over, close to the floor of the summit crater.
Seismic activity at La Soufrière, St Vincent has remained low since the tremor associated with the explosion and ash venting around noon on 22nd April. From 5:40 AM on the 30th of May to 8:00 AM (local time) on the 31st of May, there has been no recorded seismicity associated with La Soufrière according to the UWI SRC.
Persistent steaming is observable from the observatory once the cloud cover is high enough.
The alert level is orange. The volcano continues to be in a state of unrest. Escalation in activity can still take place with little or no warning. Caution should be taken in crossing river valleys on the volcano due to the increased risk of lahars (mudflows) during periods of rainfall on the volcano.
For more information on coping and handling volcanic ash, the UWI SRC is directing people to the International Volcanic Hazard Health Network for volcanic ash resources.
Official information will originate from St. Vincent and the Grenadines National Emergency Management Organization and the University of the West Indies Seismic Research Center.
