SEEN FROM SPACE: The circled area of light blue water shows discolouration from volcanic ash.
A huge pumice raft spewed up by an undersea New Zealand volcano has been captured by a Nasa satellite.
It reveals that when it erupted on July 19 it even sent up a plume of ash that went unnoticed.
The first sign of it came last week when a Royal New Zealand Air Force Orion patrol spotted the pumice and re-rerouted multi-purpose warship HMNZS Canterbury to the scene, south of the Kermadec Islands, last Friday.
They found thick pumice for as far as the eye could see.
After reading the report, Nasa searched their database of satellite shots - coming up with these.
Scientists from Tahiti and New Zealand's GNS Science connected the eruption with a cluster of earthquakes in the Kermadec Islands on July 17 and 18.
