The majority of the worldâs volcanoes are found deep underwater and now scientists have been able to record one of these eruptions as it happens to discover the sound it makes. The bubbling lava erupting from the volcanic vent Hades (above) produced a distinctive acoustic signature.
Less common are tsunami initiated by volcanic eruptions. These occur in several ways: 1  if an underwater volcano erupts, the hot lava may heat the surrounding water quickly and explosively. 2  massive flows of volcanic debris such as ash can travel down the side of a volcano and into the ocean, pushing water outwards.
