Mt Ruapehu Lahar
Posted: Monday 19 March 2007 by Chris

A lahar at the lake yesterday released 1.3 million cubic metres of water and debris which had accumulated behind a dam of soft rock built up by the 1995 volcanic eruptions.

That reduced the lake level by about 6m and nearby roads and railways were closed while the lahar emptied into Whangaehu River.

Nobody was injured and only minor damage to property was reported.

The dam of soft rock was completely washed away, meaning no more lahars like yesterday's were now expected.

The lowered crater lake at Mt Ruapehu is now at a higher risk of hydrothermal "steam-driven" eruptions, GNS Science experts say.

Mr Wakelin said water was flowing out of the lake's natural outlet as it had before the 1995 eruption.

"Now you've actually got a lake that finally can just flow in normal fashion."

He said Whangaehu River was still dirty with mud and debris, but flow levels were returning to normal.

AA 101 Must Do's for Kiwis
Posted: Saturday 10 February 2007 by Chris

Visiting Mitre Peak and Milford Sound is the country's No 1 "must-do" experience - but most Kiwis reckon there's no great reason to visit Parliament.

Or so says a 101 must-do list of the best sights, attractions and adventures on offer in New Zealand.

The Automobile Association five-month survey garnered 20,000 votes from the public which resulted in few surprises among the top choices such as Doubtful Sound, Bay of Islands, Fiordland and Abel Tasman National Park.

Landslide in Mt Aspiring National Park
Posted: Sunday 14 January 2007 by Chris

Natural causes rather than seismic activity probably triggered the massive landslide in Mt Aspiring National Park.

 

The landslip, about 150m wide and 150m long, sent at least half a million cubic metres of rock and debris crashing into the John Inglis valley floor burying an alpine lake and blocking a tributary of the Joe River.

Wakatipu DOC area manager Greg Lind said trampers in the park should take extreme care.
