Volcanic ash has continued to fall and there are warnings of more danger.
Pyroclastic currents “contain a mixture of hot lava blocks, pumice, ash and high-density volcanic gas. They move at very high speeds down volcanic slopes, usually to valleys,” according to the USGS and “destroyed almost everything in their path. “
“Based on visual observations and satellite imagery, the intervals are associated with periods of explosive activity or increased venting,” he said.
“Thunderstorms and lightning were experienced during these periods.”
Ash continued to fall on the island overnight and also the neighboring islands, the Grenadines, Barbados and St. Lucia, influenced. “Explosions and associated ash, of similar or greater magnitude, are likely to continue for the next few days.”
Prime Minister Ralph Gonsalves on Thursday issued a disaster warning due to a change in the volcano’s eruptive activity. He issued an evacuation order for all residents living in a “red zone”. Gonsalves said it could take four months for life to return to normal on the island.
Authorities said it was likely explosive eruptions could continue for “days and possibly weeks” after the first eruption on Friday stretched an ash flow that stretched 6,096 meters (20,000 feet) into the air.
La Soufrière is on the largest island of the St. Vincent and the Grenadines chain located.
