The volcano “continues to show periods of explosive activity,” said Dr. Erouscilla Joseph, director of the University of the West Indies Seismic Research Center (UWI-SRC).
Joseph reported the third blast in an audio update released Friday night. She did not provide further details about the third explosion, but it appears to have been smaller than the previous two. The center works with local authorities to monitor volcano activity.
“Take care of everyone. We are covered in ash and strong smells of sulfur enter the air. For those with respiratory problems, please take the necessary precautions to stay safe and healthy,” NEMO said.
Authorities said explosive eruptions could continue to occur “for days and possibly weeks” after the first eruption on Friday emitted a panel of ash that extended into the sky to 6,096 meters.
La Soufrière is located on the largest island in the chain of St. Vincent and the Grenadines.
The second explosion occurred at around 14:45 on Friday and was smaller than the first, according to NEMO.
Prime Minister Ralph Gonsalves on Thursday declared a disaster alert caused by a change in the eruptive activity of the volcano. The island was placed on red alert, meaning an eruption was “imminent now,” NEMO said.
Evacuation orders have been enforced in about a dozen districts in St. Louis. Vincent, affecting about 6,000 to 7,000 people, a UWI-SRC spokesman told CNN.
Kenton Chance, a freelance journalist, told CNN on Friday that he was about five miles from the Rosehall Volcano in St. Louis. Vincent. The ash was still declining, but in declining quantities, he said.
“Normally, you would have a very impressive view of the volcano,” he said. “But because of the amount of ash in the air, you can’t see it.”
