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 new seismic station constructed at the National Parks Interpretation Centre at Bamboo Range, on the eastern side of the volcano is operational. The streaming of data from this into the Seismic Research Centre (SRC) began on March 01, 2021. In addition, a new continuous Global Positioning System (GPS) monitoring station was installed at the monument recently constructed in Fancy.

Scientists have completed additional measurements of carbon dioxide in soil along the lower sides of the volcano.

Update: NEMO has advised that drone surveys and aerial photographs of the volcano were done at the La Soufriere Volcano on Wednesday 3rd March 2021. In their previous update, it was stated that “there have been no drone surveys or aerial photographs of the volcano were done at the La Soufriere Volcano over the past few days due to poor weather conditions, however, satellite observations on March 1st confirmed that the dome continues to grow slowly.”

Work has continued at the Belmont Observatory, on the installation of the seismic data acquisition system.

Three members of the Seismic Research Centre Team returned to Trinidad and Tobago on Monday, March 1st, 2021. They are Dr. Michal Camejo, Ms. Monique Johnson & Mr. Garth Mannette.

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.
