The Caribbean island of St Vincent is likely to see further volcanic eruptions and ash fall over the coming days, experts have warned.
The La Soufrière volcano first erupted on Friday, blanketing the island in a layer of ash and forcing more than 16,000 people to evacuate their homes.
Smaller explosions continued over the weekend, causing power cuts and disrupting water supplies.
Emergency officials have described the landscape as a “battle zone”.
“The volcano continues to erupt explosively with the production of copious amounts of ash,” the University of the West Indies’ Seismic Research Center said.
“Explosions and accompanying ash fall, of similar or larger magnitude, are likely to continue to occur over the next few days impacting St Vincent and neighbouring islands,” it warned.
June Shipley, who is visiting her family on the island, told the BBC there were widespread fears a larger eruption could be imminent.
“We do hear the rumblings of the volcano and we do see the smoke,” she said.
White-coloured dust has covered buildings and roads around the island, including in its capital Kingstown.
The warning to expect further activity at La Soufrière followed what officials described as an “explosive event” on Sunday.
The emergency management organisation Nemo tweeted: “Massive power outage following another explosive event at La Soufriere Volcano. Lightning, thunder and rumblings.”
It later spoke of “possible destruction and devastation of communities close to the volcano”, and compared the eruption to that of 1902, the worst in St Vincent’s history when more than 1,000 people were killed.
