Millions in U.S. Face Mega-Wave from Island Collapse

By Jeremy Lovell
LONDON (Reuters) - The bad news is tens of millions of people along
the eastern seaboard of the United States and Canada may drown if the
slow slippage of a volcano off north Africa becomes a cataclysmic
collapse.

But the good news is the world is not likely to be destroyed by an
asteroid any time soon.

Scientist Bill McGuire told a news conference on natural disasters on
Monday that some time in the next few thousand years the western flank
of the Cumbre Vieja volcano on the Canary Island of La Palma will
collapse, sending walls of water 100 meters high racing across the
Atlantic.

A chunk of the volcano the size of a small island began to slide into
the ocean in 1949. There is almost no monitoring of the volcano,
giving virtually no chance of any advance warning of another eruption
which could trigger the catastrophe.

"The U.S. government must be aware of the threat. I am sure they are
not taking it seriously," McGuire of the Benfield Grieg Hazard
Research Center told reporters. "They certainly should be worried, as
should the island states of the Caribbean."

He said the giant tidal wave or Tsunami triggered by such a collapse
would hit the other islands of the Spanish-owned Canaries within an
hour and reach the north African coast within two hours.

Between seven and 10 hours later, waves still several tens of meters
tall and traveling at the speed of a jet plane would be swamping the
Caribbean and crashing into the eastern seaboards of South and North
America.

McGuire urged the governments of Spain and the United States to fund
monitoring of the volcanically active La Palma -- a project he said
could be achieved relatively cheaply.

He said the slow collapse -- started by an eruption in 1949 -- would
almost certainly be turned catastrophic by another eruption of the
volcano which erupts every 25 to 200 years.

The last eruption was in 1971, and prior to 1949, the previous
eruption was in 1712.

"A future president of the United States must make a call on what to
do when La Palma collapses," he said.

On a brighter note, scientist Benny Peiser of John Moores University
in Liverpool told the same news conference that the threat of a
cataclysmic strike on the earth by a large asteroid was fading rapidly
as money was pumped into finding them.

Within 10 to 30 years, all the near-earth asteroids will have been
charted. Scientists believe they can find a way to steer an asteroid
out of the way of the earth, as long as they have enough warning it is
coming.

That leaves the field clear for Hollywood to move on to volcanic
eruptions and tsunami for the next generation of apocalyptic movies.
