More about this image
The Ocean Observatories Initiative cabled array infrastructure at the site is the most advanced submarine volcanic observatory in the world's oceans. It hosts 20 instruments that provide real-time data on linkages among geophysical, chemical and biological processes operating in this dynamic system. The base of the volcano also hosts two ~ 2600 meters-tall, state-of-the-art moorings with an instrumented wire crawler and winched profiler.
On April 23, 2015, seismic and seafloor pressure data streamed live to shore showed that during a 24 hour period, nearly 8000 earthquakes occurred and the seafloor dropped 2.4 meters, marking the start of the eruption.
