The outage was confirmed by the emergency management organisation Nemo, which tweeted: “Massive power outage following another explosive event at La Soufriere volcano. Lightning, thunder and rumblings.”
Experts have also warned about the damage the ash can cause to crops and buildings.
Professor Richard Robertson of the University of the West Indies Seismic Research Centre said: “And probably, the roofs are going to fail and you are going to have a lot of property damage… that is simply because of the ash.
“That is unfortunate but I suspect that as you go further south, it is going to be less of an impact, but certainly, the environment has been damaged badly by the heavy ash fall.”
Unfortunately, Prime Minister Ralph Gonsalves fears it could take up to four months after the eruption ends before life returns to normal.
