Present La Soufrière Alert Level:ORANGEThere 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.

The National Emergency Management Organization, in their latest bulletin, advised that the gas plume coming from the dome at La Soufriere continues to cause damage to vegetation in the summit areas on the south-western side of the volcano.

Scientists have also begun to measure carbon dioxide in the soil along the lower sides of the volcano.

A monument to be used as a benchmark for a new continuous GPS monitoring station was constructed at the Fancy seismic site. Work also continued at the Belmont Observatory with the installation of the seismic data acquisition system.

A virtual community meeting for the North Leeward Community will be held today, Tuesday 2nd March 2021 beginning at 6:00 p.m. The meeting would be carried live on local NBC Radio and VC3 TV (channel 114), NEMO’S Facebook page, UWI tv Global (, uwiseismic YouTube channel, and Grenadines Radio.

There is NO ‘explosive’ eruption at the La Soufrière volcano at this time. La Soufrière continues to have effusive eruptions as hot magma reaches the surface at extreme temperatures. This appears in the night as fire or a bright red glow above the crater. As the dome gets higher and closer to the crater’s rim, this phenomenon will continue to be visible on clear nights.

The alert level remains at Orange. The volcano continues to exude magma on the surface and steam can still be observed from the Belmont Observatory. Persons living in areas close to the volcano should expect strong sulfur smells for several days to weeks, depending on changes in wind direction.

The NEMO is reminding the public that no evacuation order or notice has been issued. NEMO continues to appeal to the public to desist from visiting the La Soufrière Volcano and especially going into the crater since doing so is extremely dangerous.

The @uwiseismic and NEMO continue to advise access to the #LaSoufriere Volcano is strictly prohibited at this time….

According to the SRC, the new volcanic dome is extremely dangerous for those in close proximity as it can explode at any time without warning. People have been killed in this way. This warning comes as images from a birthday photoshoot surfaced on social media.
