Situation Reports

SITUATION OVERVIEW

  • At 4:05am there was a huge Pelean style explosion accompanied by pyroclastic density currents on the south and south western flanks of the volcano
  • The domes formed in 1979 and 2021 have been destroyed and a deep crater with a vent now exists
  • Explosions are ongoing
  • SRC has lost connection with 4 of its 8 seismic stations and new
    seismic stations will be installed when it is safe to do so
  • The remaining 4 stations will provide the ability to monitor the
    activity and will be augmented by satellite imagery

SITUATION OVERVIEW

•Explosive events continue with significant venting of ash.
•Ashfall occurred in most areas of the island overnight and in the Grenadines, Barbados, Saint Lucia and Grenada.
•Rainfall has added to the weight of ash on buildings and the remobilization of material in streams, valleys and on hills.
•Scientists informed of possible pyroclastic flows on the eastern side of the island.
•There were some reports of individuals with respiratory concerns.

Between the 29th December 2020 and 7th April 2021, the alert level for the La Soufrière volcano in St. Vincent and the Grenadines had been elevated to Orange as a result of increased activity and an ongoing effusive eruption.

On 29th December 2020 the alert level for the La Soufrière volcano in St Vincent and the Grenadines was elevated to Orange because of increased activity at the site. The volcano has had an effusive eruption, with visible gas and steam eruption and the formation of a new volcanic dome. The volcano continues to exude magma on the surface and gas emissions can be observed from the Belmont Observatory. A UWI Seismic Research Centre team is currently in St Vincent to support monitoring and data collection and analysis.
