From GNS:

 

 

Recent visits to the volcano have confirmed an increase in the output of volcanic gas from Mt Ruapehu’s Crater Lake. Moderate levels of volcanic tremor continue and the lake temperature measured by the outlet data logger is 45 ºC. The increase in gas output, the high lake temperature and continued seismicity suggest that Ruapehu is at a higher level of volcanic unrest. As a result, GNS scientists revise the Volcanic Alert Level to Level 2 (moderate to heightened unrest). The Aviation Colour Code is also changed, from Green to Yellow.

 

 

 

 

Of course it could die down and fall back to normal background activity, or it might really upset skiers this season.

Was there always water before the last big one in the 90's? Reason I ask is that lava pressure and water are a bad combination, that might magnify an eruption

It's a worry for Tourism. Overseas headlines in an event tend to look like 'New Zealand just exploded! It's huge!!' National strategy needed ; ).

The crater lake tends to partly or fully empty out when it erupts, then re-fill between events.  Lahars due to buildup and collapse of unstable deposits have been a problem (ie Tangiwai).  Historic eruptions have been very small, but prehistoric eruptions not so small.  Depends how you define small and large, NZ could at any time let rip with a volcano 10 to 1000 times more explosive than Mt St Helens, Krakatoa, Tarawera, as it's done that in the past (1800 years ago, Taupo erupted and ejected 30 cubic km of material in a few minutes, eventually ejecting 150 cubic km).  If (when????) that happens again, the consequences are global.

 

Yes - white Island erupted a week ago - quite small though, nothing unusual, not connected.

Yep we were at Whakapapa during the 90's eruptions and got some great shots. I wouldn't do it now though as I could run quite fast then and the rocky surface up there is a pain in the butt for a wheelchair.

Hey Mike - slightly OT, but do you know how accessible the mountain is?  Has you been up there in your chair?  Its something I have been thinking of for a family member buts its a long way to go to find out its not wheelchair accessible.

The Chateau is fine as is the lower car park towards the top but beyond there is hopeless for a chair. Top of the Bruce is next to impossible. It has been a while since I have been though.

I wouldn't be trying to get a refund on a season's pass just yet.  Geonet/GNS monitoring is very good (world class) subject to the proviso that anything could happen very suddenly and unexpectedly anyway.

 

More of a threat to skiing plans may be the weather.  It's very warm here (Chch), I'm still harvesting tomatoes from the garden, not a hint of a frost yet (though on the Port Hills here we get very few anyway) and very little rain.  Any cold snap has been short-lived, then reverts to warm N/NW patterns.

That would certainly be a way to get house prices in Auckland to drop like a stone. Also overseas buyers wouldn't want to buy near an active volcano. I think people have underestimated the volcanos in Auckland, as nothing has happened in our lifetime.

Auckland is a different flavor of volcano though. With basalt shield type cones like in Auckland, an existing cone is about the least likely place for a new one to spring up, as the crust is that much thicker there.

 

A new one popping up in the harbor near Rangitoto would make things interesting though!
