January 3 marked the 24th anniversary of Kilauea’s LONGEST RIFT-ZONE ERUPTION IN THE LAST 600 YEARS. In the early years of this eruption, lava fountains as high as 460 m (1,500 ft) burst from Pu`u `O`o every three to four weeks. In the summer of 1986, the eruption shifted to a new vent, named Kupaianaha, 3 km (1.9 mi) downrift. Kupaianaha was the site of continuous eruption for the next 5.5 years. The eruption changed its style as well as its location, becoming less exuberant with age. Episodic lava fountains were replaced by quiet, steady effusion. Lava reached the ocean in November 1986, traveling through lava tubes most of the way. Vog became an island issue as the continuous activity produced a pall of sulphurous air that has been with it ever since. The past year has been relatively quiet, with lava flows mostly recoating older flows
NEW ZEALAND - The possibility of a lahar at Mount Ruapehu is now becoming more of a reality. The tephra dam at the Crater Lake that formed in the 1995 and 96 eruptions is eroding away. Department of Conservation scientists spent yesterday on the volcano seeing how much damage rising water is doing to the tephra dam blocking the flow out of the crater lake. The water seepage has now doubled compared to what they found on December 29. It is a trend which will continue. Scientists believe there's no need to worry. There will be enough warning time, so the risk to property and life in the area has been minimised.
