The La Soufrire volcano in Saint Vincent and the Grenadines has seen an increase in eruptive activity, with multiple explosions starting on Friday, April 9, triggering pyroclastic flows - dangerous and fast-moving avalanches of hot ash and gas. However, a NE-SW alignment of epicentres beneath the NE flank of the volcano emerged in one swarm of volcano-tectonic earthquakes (VTs) and later nests of VT hypocentres developed beneath the volcano and at a separated location, under St. George's Hill.
