Mud flowed down Mt Ruapehu's slopes but no lava was produced
Impact craters
Vulcanologist Brad Scott flew over the site after the short eruption on Tuesday evening. "The top of the mountain is black, covered in crater-lake mud and ash," he told Radio New Zealand. Craters caused by rocks and debris could be seen up to 1.5km (almost one mile) from the summit, he said.
The eruption was caused by the build-up of steam under the crater lake rather than new lava flowing into the volcano, he said. Experts have not ruled out further eruptions and the mountain's ski area remains closed, the Dominion Post reported. At 2,797 metres (9177 feet), Ruapehu is the North Island's highest mountain and one of New Zealand's most active volcanoes. An eruption in 1995 sent boulders the size of cars flying through the air.

# Mount Ruapehu eruption sends ash and steam nearly three miles into the air

WELLINGTON, New Zealand (AP) -- An erupting volcano sent ash and steam nearly three miles into the air Tuesday, while mud and rocks raced down the mountainside and injured at least three people, officials said. The Mount Ruapehu eruption sent mud sweeping through a ski area, prompting officials to evacuate the zone and close nearby roads, local district council spokesman Paul Wheatcroft said.
A 22-year-old hiker was injured by a rock that crashed through a mountain shelter and struck his legs, rescue officials said. "It took quite an effort to get the material off his legs," said rescuer Andy Hoyle. The man was hospitalized in intensive care.
One mud flow temporarily trapped a snow groomer at a ski area, and two other workers there suffered minor injuries, Wheatcroft said.
Airplane pilots reported seeing a cloud of ash and steam nearly three miles above its normally snow-capped peak, left coated with mud and ash. "The top of the mountain is black ... that goes out about a half-mile from the summit," vulcanologist Brad Scott said. About 60 skiers at two ski lodges were evacuated from the mountain before the short, sharp eruption was declared over. Roads and rail tracks near the mountain were closed by police, but later reopened. Mt. Ruapehu in central North Island has erupted five times since 1969, with one in 1995 causing widespread damage when it tossed huge quantities of ash and rocks -- the size of large cars -- from its crater.
