Roundup of Global Volcanic Activity
Axial sea Mount (Oregon, USA) An underwater volcano off the coast of Oregon has risen from its slumber and may be spewing out lava about a mile beneath the sea. Researchers were alerted to the possible submarine eruption of the Axial Seamount, located about 300 miles (480 kilometres) off the West Coast, by large changes in the seafloor elevation and an increase in the number of tiny earthquakes on April 24. Axial Seamount is an underwater mountain that juts up 3,000 feet (900 meters) from the ocean floor, and is part of a string of volcanoes that straddle the Juan de Fuca Ridge, a tectonic-plate boundary where the seafloor is spreading apart.
