GeoNet Duty Volcanologist Agnes Mazot says: “These changes show that Ruapehu is experiencing signs of elevated unrest above known background levels.” Mount Ruapehu’s Crater Lake experienced eight heating cycles since 2002, with temperatures peaking at 42.5°C in May 2003, but previously no seismic activity has been observed during times of high temperatures.

But even though Mount Ruapehu remains an active volcano (it last blew its top in 2007, producing ash and rock fall) there is no indication of a looming eruption. So at the moment is doesn’t look as if the planned opening days for Mount Ruapehu’s Whakapapa Ski Area (2 July 2011) and Turoa Ski Area (25 June 2011) have to be pushed back. And hey, if Mount Ruepuhu wasn’t bubbling every now and then it would lose its unique thrill of being a live volcano to ski on!

The last day of spring will also signal the last day for snow enthusiasts to purchase their super cheap 2010 Mt Ruapehu season passes, and have that price frozen until the 2012 season. Why not pick up a cheap season pass to give a snow-loving friend for Christmas while the offer’s open?

“This really is the best season pass deal on offer at the moment and it’s perfect timing for Christmas,” says Mike Smith, Mt Ruapehu marketing manager. “There has been huge interest in the price freeze offer this month, and this has been helped by the record-long season Mt Ruapehu enjoyed this year.”

2010 season passes are on sale until next Monday (30 November) for the discounted price of $370 (adult) and $230 (youth). To take advantage of the three-year price freeze deal, you must purchase a season pass each succeeding year at the same time. And also, if you purchased a 2009 season pass in November 2008 for $350, you’ll keep paying only $350 until 2011 (for the 2012 season) if you purchase a pass over consecutive years.
