(NATIONAL) -- An underwater volcano some 300 miles off the coast of Oregon has erupted after a long period of sleep.
The eruption,which appears to feature discharging lava from the volcano, has triggered numerous earthquakes but geologists studying the eruption say there is no immediate danger to anyone.
The volcano is called the Axial Seamount and is located deep under the ocean on what is called the Juan de Fuca Ridge, just under 300 miles west of Cannon Beach, Oregon.
The Axial Seamount was first detected in the 1970s. It sits on top of the Juan de Fuca Ridge, where hot magma makes its way up from deep in the earth to fill a reservoir underneath the volcano.
Almost 8,000 earthquakes have been picked up by instruments and geologists knew the source of the quakes was an underwater volcano as they tend to send out different type of waves than regular tectonic-plate earthquakes.
Scientists are observing the eruption in real time thanks to monitoring instruments that have been placed on the sea floor off the coast of Oregon.
John Delaney, an oceanographer at the University of Washington in Seattle is quoted in zmescience.com as saying “This (using instruments to observe an underwater eruption in real time) is what I’ve been dreaming about for decades. This is a new era of exploration in the Earth sciences.”
Delaney was one of the people behind the movement to send data from Axial to shore along a sea floor cable.
