Fin Whale

Caption: A seismometer was inserted into a hole drilled in seafloor lava. Eight of these instruments were installed at an ocean spreading-center volcano 150 miles off Vancouver Island. A data recording device is enclosed in the yellow sphere. In three years of operation the network detected nearly 40,000 small earthquakes, and hundreds of thousands of fin-whale calls.
