Ruapehu vulkaan (Nieuw-Zeeland): tekenen van onrust, alert niveau verhoogd

Friday Nov 16, 2012 07:51 AM | DOOR: T

Nieuw-Zeeland wetenschappers toezicht Ruapehu vulkaan waargenomen tekenen van verhoogde vulkanische onrust en verhoogde het alarmniveau van de vulkaan. De kans op nieuwe uitbarstingen in de komende weken tot maanden is toegenomen, GNS Science zei in hun laatste persbericht.

GNS wetenschappers steeds meer kleine aardbevingen ongeveer 5 km onder de top gebied van Ruapehu opgenomen, en denk dat de temperatuur op op de bodem van het meer openingen is ongeveer 800 deg C, hoewel het meer zelf slechts 20 is deg C en de temperatuur sinds januari dit jaar is afgenomen.

"Dit suggereert de vent die tot de opbouw van een druk onder kratermeer leiden kunnen gedeeltelijk wordt geblokkeerd. Een plotselinge release van de druk kan leiden tot een uitbarsting", GeoNet schrijft.

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.
A similar event happened in 1953 killed when a lahar killed 151 people when it washed away a rail bridge, plunging a passenger train into the raging torrent of mud.
