Massive seafloor craters found in waters off New Zealand

An international team of scientists have found what they believe are the world’s biggest ” pockmarks” — craters formed by seafloor eruptions of gas or fluids — in waters off New Zealand. The New Zealand, German and U.S. scientists found the pockmarks at a depth of about 1,000 meters on the seafloor of the Chatham Rise, about 500 km east of Christchurch.

The three giant pockmarks, the largest measuring 11 km by 6 km in diameter and 100 meters deep, were possibly twice the size of the largest pockmarks recorded in scientific literature, said a statement from New Zealand’s Institute of Geological and Nuclear Sciences (GNS Science).
