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

The National Emergency Management Organization (NEMO), in their latest bulletin, advised that there have been no changes in activities at the La Soufrière Volcano over the past 24 hours.

Volcano-Tectonic (VT) earthquakes continue to be recorded beneath the volcano and their magnitude is such that they can be felt in villages such as Fancy, Owia, Point and Sandy Bay.

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.

NEMO is also encouraging residents especially persons living in communities close to the volcano to heighten their preparedness in the event that it becomes necessary to evacuate at short notice.

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.
