William said the eruption was enough to trigger several warnings.
“The volcano activity increased a little bit to explosions, that propelled ash to some 100km that fall around the submarine volcano.
“We gave advice to the aviation industry as well as the marinas to stay away from the east of Epi island region,” he said.
A watch alert was issued for other islands surrounding Epi.
The underwater volcano is one of a series of active underwater volcanic cones and a caldera which last erupted in 2004.
These series of submarine volcanoes are generally referred as East Epi, and the three bigger cones have specific names, from west to east, Epi-A, Epi-B and Epi-C.
All of these cones have had intermittent activity in this and the last century.
