In this Thursday, Aug. 9, 2012 photo released by New Zealand Defence Force, pumice rocks are shown at an unidentified location after the rocks were collected from an area of floating pumice near South West of Raoul island, off New Zealand's coast. A mass of small volcanic rocks nearly the size of Belgium was discovered floating off the coast of New Zealand. The stretch of golf-ball-size pumice rocks was first spotted this week by a New Zealand air force plane about 1,000 kilometers (620 miles) northeast of Auckland. Scientists said the rocks likely spewed up in an eruption by an underwater volcano. (AP Photo/New Zealand Defence Force, Nicole Munro) EDITORIAL USE ONLY less
