Is this island moving?what on earth

August 1,2012 as a passenger jet travels above the pacific ocean almost 500 miles from the newzealand coasts the pilot spots something in the water below him the pilot looks out the window and see what looks like a gaint island in the south pacific the pacific holds around 25,000 islands the plane is nowhere near of them this is supposed to be open ocean there should not be visible than water for hundred miles investigator immediatly consult scans of the area taken by nasa's terra satellite recent images confirm their suspicion something has materialized in the middle of now where whatever it is they found was not there before it just appeared out of now where would it have come from ?what actually are we looking at 9 whatever the thing is how ever it appeared it's more than 200 hundred miles long the scale of this is enormous this is the size of small century when analysis compare the coordinates of the pilot sighting with the latest satellites images they discover disturbing this  object appear to be moving and islands do not move the anamaly moves relentlerly toward land the pressure to work out what it is and where it come from builds like all geologic investigations it really comes down to getting  a sample to analyse someone really needs to get a piece of this material on august 9th a full weak after the initial sighting the newzealand navy dispaches a ship to study the strange phenomenon the ship goes to investigate and what they find is something that is 300 miles long and 30 miles wide and captain reports that it is the strangest  thing he is ever seen it is a unique and bizarre thing to witness and it look like mind or rooms  kind of dirt the skin this mass of rock just floating on the surface of the water the concepy of a gaint mass of rock moving across the ocean seems to defy the laws of physics but the navy's examination of the sample proves that's exactly what it is the weired stones are pumice type of light weight rock formed when undersea valcanol eject lava into the water when pumice is formed the volcanic eruption injects a lot of gas bubble into the lava and they get trapped inside the rock it become buoyant and floats to the surface of individual pumice stones floating across the ocean like a country sized raft if there is enough pumice all gathered in one spot it can look likeba solid island but it's not
