As I was looking through the images of the Volcano Cams from GeoNet.org.nz, I found this cool picture taken looking at Raoul Island in the rain and sun with two cool rainbows!
The Kermadec Islands, located about 750 – 1,000 km north-east of New Zealand, are some of the most active offshore volcanoes in New Zealand. The Kermadec Islands are the summits of large volcanoes that have been built on the crest of the Kermadec Ridge. There are also several submarine volcanoes.
The Islands are the summits of large volcanoes that have been built up on the crest of the Kermadec Ridge, and have emerged above sea level. The ridge stretches for 600 to 700 km north-north-east, and has been upraised by the ongoing collision between the Pacific and Australian plates. Raoul Island is the summit of a large submerged massif about 35 km by 20 km; it is an anvil-shaped island about 30 km2 in area, and contains a large central depression (caldera) formed largely by subsidence immediately after large eruptions. Just west of Raoul Caldera is Denham Bay, a second caldera which has been flooded by the sea.
Pretty cool hah?! 😛
