Hawaii authorities on Saturday told several dozen residents near an active lava flow to prepare for a possible evacuation in the next three to five days as molten rock oozed across a country road and edged closer to homes. The flow was about 35 yards wide and moving northeast at about 10 yards per hour. Lava of some 2,000 degrees Fahrenheit crossed a road on the edge of Pahoa, the largest town in the mostly rural region of Puna on the Big Island of Hawaii, at 3:
Scientists have created the highest resolution map yet of the ocean floor, revealing thousands of underwater mountains and extinct volcanoes that were previously unknown. In a study published Thursday in Science, researchers say the new map is at least twice as accurate as the previous version assembled nearly 20 years ago even though it can only resolve features that are a mile high and bigger. “You might think, that’s not so much better, but instead of seeing 5,000 old volcanoes down there, now we can see 10,000,” said David Sandwell, a geophysics professor at the Scripps Institution of Oceanography at UC San Diego who led the study.
The number of volcanoes that are erupting continues to rise, and scientists cannot seem to explain why this is happening. In 2013, we witnessed the most volcanic eruptions worldwide that we have ever seen in a single year, and this increased activity has carried over into 2014. In recent months, we have seen major volcanoes roar to life in Russia, Peru, Hawaii, Reunion Island, Indonesia, and all over Alaska.
An intense earthquake swarm continues to rattle Iceland’s Bardarbunga volcano, adding to fears that a potential eruption could disrupt the region’s air traffic. Weather officials say they detected about 1,000 small quakes through Tuesday night, which were triggered by an unusually strong earthquake on Monday. The tremors are tied to the increasing movement of magma underground.
