For several days, the volcano has become increasingly active.
During the night until Friday, the situation was judged to be urgent.
At short notice, an evacuation of the island was ordered.
Earthquakes have been felt in the area and it is judged as a sign that lava is about to penetrate to the surface, reports The Guardian.
In the worst case, the volcano is expected to erupt within a few hours, reports the local news site New784.
According to the authorities in the country, a cruise ship is on its way to the island to help with the evacuation.
The island of Saint Vincent has 110,000 inhabitants.
The last time the volcano erupted was in 1979, but then the population was warned in good time and no one was injured.
The volcanic eruption before that took place in 1902 and then over 1600 people died.
