From "How Stuff Works"
- At a news conference on natural disasters, scientists warned that a
volcano on the Canary Islands is slowly slipping into the ocean, and
if it erupts again it could collapse and cause a tidal wave that
would head straight for the east coast of the United States and
Canada. The Cumbre Vieja volcano erupts every 25 to 200 years; the
last eruption was in 1971.
