Lahar in the Rabacca Dry River, which flows from the mountains of the La Soufrière Volcano, northeastern St. Vincent. (5:07 PM, April 13th, 2021, Hayden Billingly)
|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 information received from the scientists at the Belmont Volcano Observatory, there were lahar flows within the river system in the Red and Orange Volcano Hazard Zones from 9:00 AM to 10:00 AM Tuesday 27th April 2021.
Lahars are a dense mixture of ash and water. This usually occurs during heavy rain which creates mudflow that destroys everything in its path as it rushes down the volcano’s slopes faster than a river.
The lahars can pose a danger to persons visiting the Red and Orange Zones. As a result of this, the Royal St. Vincent and the Grenadines Police Force will be restricting persons traveling into the Red and Orange Hazard Zones.
According to the forecast received from St. Vincent and the Grenadines Meteorological Services, occasional showers are expected to continue during the course of the day and from late Wednesday into the end of the week. Residents and motorists should remain alert due to rain-soaked ash and possible poor visibility due to volcanic ash.
The National Emergency Management Organization (NEMO) is also urging persons to desist from visiting the Red and Orange Volcano Hazard Zones due to the potential danger.
According to the UWI SRC, the volcano continues to erupt. Its pattern of seismic activity over the last few days is typical of the growth and destruction of lava domes. Explosions with accompanying ashfall, similar to or larger, can occur with little or no warning impacting St Vincent and neighboring islands.
The alert level remains red. The National Emergency Operations Center continues to be fully functional operating on a twenty-four-hour, around-the-clock basis. NEMO will continue to provide regular updates as they continue to monitor the Volcano.
Official information will originate from St. Vincent and the Grenadines National Emergency Management Organization and the University of the West Indies Seismic Research Center.
