Massive Underwater volcanic eruption near Spanish Canary
island

Valverde, Spain (AFP) Oct 10, 2011
An massive underwater volcano erupted just off Spain's El Hierro
island in the Canaries, which has been rocked by thousands of
small tremors since July, local officials said Monday.
The effects of the eruption, some five kilometres (three miles)
from the island at a depth of more than 500 metres (1,500 feet),
will not be felt on the island, said volcanologist Alicia Garcia
of the Higher Council of Scientific Research.
"The earthquake monitoring stations on the island recorded the
start of an eruption overnight. There is no visible manifestation
at the moment," she told AFP.
The regional government of the archipelago issued a "yellow"
volcanic eruption alert -- the second level on a scale of four --
after the island was hit by a 4.3-magnitude quake.
The earthquake was the strongest of more than 8,000 tremors which
the Spanish National Geographic Institute has recorded on El
Hierro since they began in July. The majority have been too small
to be felt.
"There was a volcanic eruption overnight, what we don't know is
what is its state, if it has just started and if it is just
releasing gases or if it is releasing magma as well," the head of
the island's local council, Alpidio Armas, told Spanish public
radio.
"If the magma gets out, which appears will be the case, it will
mean that the seismic movements will decrease," he added.
Armas said no further safety precautions were necessary on the
island, but that a security perimeter marking the eruption area in
the sea would be needed.
El Hierro, which means iron in Spanish, is the smallest of Spain's
Canary Islands, located in the Atlantic off the coast of Morocco.
It is home to some 11,000 people.
The last volcanic eruption on the Canary Islands was on nearby La
Palma in 1971.
