WELLINGTON, New Zealand, Nov. 16 (UPI) -- A volcano in the center of New Zealand's North Island is showing signs of a possible imminent eruption, vulcanologists in the country are warning.
The Institute of Geological and Nuclear Sciences said the temperature beneath Ruapehu's Crater Lake was 1,400 degrees Fahrenheit but the lake itself was only 68 degrees F., suggesting a volcanic vent may be partly blocked.
