Volcanic eruption 350km off BoP coast

There has been a recent large volcanic eruption in the sea 350 kilometres off the Bay of Plenty coast.

Using underwater mapping devices, scientists have found evidence of the eruption by the Rumble III Volcano near the Kermadecs.

A map made in 2007 shows an 800 metre wide crater near the top of the underwater volcano and a new map shows the crater has been filled and the cone reduced in height by 100 metres. http://www.newstalkzb.co.nz/newsdetail1.asp?storyID=154043
