Zavien, I gotta go against you on this one. A seamont forms slowly over time - first volcanic eruptions builds it up and then erosion and subsidence sends it below water - the Sumatra quake might have moved it in any one direction up to a couple of millimeters, but definitely not in a manner that would have created a hazard where none existed before.
The Navy went back to some old satellite data and spotted the seamount - underwater features generate variances in mean sea level.
Thanks anyway...I guess National Geographic is faking it too :)
