 Current seismic signal from Ruapehu (GeoNet) Mittwoch, Dez 05, 2012
On 3 December, GeoNet reported that monitoring data suggested that Ruapehu continued in a state of unrest. Scientists aboard an overflight observed that the crater lake was quiet and that the temperature remained steady at 22 degrees Celsius. Seismicity had decreased since the early part of November.

Ruapehu volcano who last erupted in 1995-96 might be heading towards a new eruptive cycle. The temperature of the crater lake has increased to 40C and other indicators such as seismicity and deformation all point towards a gradual reawakening.

Sunday morning at 10:47 am local time, a section of Ruapehu volcano's crater walls collapsed under the pressure of the crater lake. The sudden draining of the lake caused a devastating lahar that travelled down from its altitude at 2500 m to sea level. Fortunately, the flash flood of mud drained through a river channel and no people were injured or killed. Authorities closed roads and the nation's main trunk rail track near the southern base of the mountain on New Zealand's North Island. |
