At Raoul, two new submerged caldera volcanoes were found. Both volcanoes have relatively small craters, some 4 km in diameter (just under a fifth of Ruapehu's crater diameter and half that of Wellington Harbour). One crater is very deep, measuring about 1000 m from the rim to the crater floor. Both volcanoes appear geologically young in the order of thousands of years old but laboratory analysis of sediments will be needed to properly assess their age.

 Two new New Zealand volcanoes discovered.
Geologists  have discovered two new underwater volcanoes off the north-east  coast of New Zealand.
 The Geologists were working in the Kermadec Arc, near Raoul Island, when they made their discovery.
The  volcanoes are relatively small,  with crater summits about one-fifth the size of Mount Ruapehu's; however, one  volcano has a crater that measures 1000 metres in depth from  the rim  to the crater floor.
