The Kilauea volcano has been erupting since May, after a 6.9 eruption caused an earthquake that swallowed roads and homes and sent ash spewing 30,000 feet into the air. Researchers hope to determine the stability of the ocean floor near the erupting volcano in Hawaii, and so they've put a dozen seismometers on the ocean bottom this summer, with plans to retreive them in September.
