Tectonics trigger underwater volcanism

In 2006, a large eruption occurred on the seafloor about 1,000 kilometers off the coast of Mexico. Geochemical dating of the erupted lava suggested the event went on for up to 10 months. Now, researchers taking a closer look at seismic and audio recordings made during the event have found that the eruption likely occurred over a much shorter period — a matter of days instead of months. The findings shed light on the sequence of events leading up to the event, as well as on the mechanisms of such seafloor eruptions.
