In 2009, a video camera and a hydrophone were floating 1,200 metres (3,900 ft) below sea level in the Pacific Ocean near Samoa, watching and listening as the West Mata Volcano erupted in several ways. Putting video and audio together let researchers learn the sounds made by slow lava bursting and the different noises made by hundreds of gas ...
Video of the volcano showed lava spewing into the air. According to the Icelandic Meteorological Office , the volcano shot lava about 50 meters (about 165 feet) high and came from a fissure that ...
