A remote undersea volcano is likely erupting in the Pacific Ocean
LA TimesA Japanese weather satellite captures an image of an undersea volcano in January. A volcano is likely erupting deep beneath the Pacific Ocean in the U.S. commonwealth of the Northern Mariana Islands, but scientists don’t know for sure because it’s so inaccessible. With help from the the Laboratoire de Geophysique in Tahiti and data from seismic stations in Guam and Japan, scientists analyzed the signals to determine that the source of the activity was likely Ahyi Seamount, the USGS said in a statement. “There are no local monitoring stations near Ahyi Seamount, which limits our ability to detect and characterize volcanic unrest there,” the agency said. “We will continue to monitor available remote hydrophonic, seismic, and satellite data closely.” The seamount is part of the Mariana Volcanic Arc, which is a chain of more than 60 active volcanoes stretching over 600 miles west of and parallel to the Mariana Trench, the world’s deepest point.
