Pretty neat. Iwo Jima is actually a large Caldera that has uplifted over 130 feet since 1779 (makes the bulging at Yellowstone look like a joke) but Iwo Jima itself has never had anything but tiny eruptions.
There was a similar submarine eruption offshore in 2001.
Has there been any unusual seismicity reported?

Now haw does a submarine erupt? A bunch of angry sailors perhaps???
Yes, I know the meaning, just couldn't resist.
