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 ...
The ongoing eruption at Hawaii’s Kilauea volcano refuses to let up after scientists say the eighth eruptive episode began late Monday night and sent lava shooting high into the air.
The plume hypothesis was simulated by laboratory experiments in small fluid-filled tanks in the early 1970s. [12] Thermal or compositional fluid-dynamical plumes produced in that way were presented as models for the much larger postulated mantle plumes. Based on these experiments, mantle plumes are now postulated to comprise two parts: a long ...
