Another issue they may strike when they finally get the black box locator going in April ... the topography of the ocean bed in that area contains underwater volcanoes that are seeping lava and constantly changing the ocean bed, forming ridges and valleys.

Even if the search does find verifiable wreckage from MH370 on the surface, marine geologist Dr Robin Beaman said underwater volcanoes would probably hamper efforts to recover the black box flight recorder from the depths.
Mr Beaman said the Southeast Indian Ridge cut directly through the search area, meaning the sea bed was rugged and constantly being reshaped by magma flows.
He said the ridge was an “extremely active’’ range of volcanoes sitting at an average depth of 3000 metres, which marked the point where the Antarctic and Australian tectonic plates are pulling apart.
