Sound Waves Help Scientists Track Volcanic Eruptions

JoAnna Wendel, freelance science writer and illustrator by JoAnna Wendel 5 April 20162 May 2022

When sound waves hit the ground, they shake seismometers like earthquake waves. Scientists can now use these sound-induced seismic waves to investigate volcanic activity.

Diverse chemosynthetic communities thrive on undersea asphalt volcanoes that form above natural oil reservoirs deep below the seabed.
