Under the Volcano

Somewhere on Earth, beneath its ocean, a volcano is erupting. As you read this, there are probably several submarine volcanoes spewing forth lava, creating new seafloor and renewing deep-sea hydrothermal vent fields that support unique animal communities.  These erupting volcanoes lie along the globe-encircling mid-ocean ridge system, the largest continuous structural feature of our planet.  This volcanic activity is not cataclysmic, but is the signature of a living planet, one that is evolving and one that is capable of hosting life.
