La Soufrière, St Vincent Scientific update 17/04/21 6:00 pm

  • The swarm of long-period and hybrid earthquakes continued at La Soufrière.
  • The rate of occurrence of these earthquakes has remained near-constant since the last update. No episodes of tremor have been recorded in the last 12 hours.
  • The continuous GPS (Global Positioning System) network has shown a change in horizontal and vertical movement since the initial deflation observed after the April 9 explosive episode.
  • The continuous GPS (Global Positioning System) network is used to track changes in ground shape on and around the volcano.
  • These changes may suggest magma is being added from deep within the sub-volcanic system, however, more investigation is needed to confirm this interpretation.
  • The volcano continues to erupt although explosive activity appears to have ended at this time.
  • Its current pattern of seismic activity may indicate growth of a lava dome, but this has not yet been confirmed.
  • Explosions with accompanying ashfall, of similar or larger magnitude, could restart in the future impacting St. Vincent and neighbouring islands.
  • The volcano is at alert level Red.
