Present La Soufrière Alert Level:REDAn eruption is in progress or may begin without further warning.

The National Emergency Management Organization, in their latest bulletin, advised that the electronics team led by Mr. Ian Juman installed a camera and EDM reflector on the southern crater wall. The camera will be used to help track the growth of the dome while the EDM reflector would be used to check for possible instability of the southern crater wall.

Full advantage was taken of the general clear conditions at the summit today to achieve several tasks. Aerial photographs and video of the volcano were taken, through the assistance of Drone Pilot Rommel De Freitas and Professor Robertson.

The other members of the Seismic Research Centre (SRC) and Soufriere Monitoring Unit Team spent the day at the Belmont Observatory testing and preparing other monitoring equipment for future deployment.

NEMO and the SRC will be hosting a Virtual Community Meeting with residents of Georgetown on Tuesday 26th January, 2021, beginning at 6:00 p.m. to update residents on the latest development at the La Soufriere Volcano and to discuss the Georgetown Community Evacuation Plan. This meeting will be broadcast live on NBC Radio, VC3 TV, NEMOSVG Facebook Live, UWI Seismic YouTube Channel and UWI TV Global.

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.
