Volcanic gas output has increased slightly http://info.geonet.org.nz/pages/viewpag ... Id=4292681

I wonder if the increase in gas is just caused by the lake drying out?

I don't think so - the gas will get to the surface just as well lake or no lake (unless it was a very deep lake...)

GNS scientists say it is quite likely that the increases in sulphur gases are caused by re-heating and movement of elemental sulphur in the hydrothermal system surrounding the new magma beneath the crater.

Awesome footage by Geoff Mackley taken today!

Extraordinary place!

White Island drum is the busiest I have seen it so far, I count 29 volcanic quakes!

Make that 38 in the past 24 hours

Clearly there is more than just a little bit of magma working its way up... exciting stuff!

Nuts!!! I can't even count them. There's too many. Every 2.5 min there is another. It's really ramped up in the last 5 hours.

Heaps of steam but I think that is to do with higher humidity today

Yeah it's getting hard to count them now, but I just counted 48 on the latest drum, can't guarantee I got them all though

Seems to have dropped off once again

Finally an update

http://info.geonet.org.nz/pages/viewpag ... Id=4292703

Aviation colour code reduced to Yellow.

Just as they update the advisory...she is ramping up again, volcanic tremor is anyway

I was just about to post something similar

ha! that happened last time they reduced it too!

Current drum image

Significant quake this morning?

I do wish they would increase the scale from the 3000 it seems to be stuck on.

I think that was the 6.3 north of East Cape just after 6pm Saturday.

Yep, I agree in hindsight, but the little ones present overnight look like they could be small volcanic ones.

ScottyD · Unread post by **ScottyD** » Mon 18/02/2013 07:49

I agree. It must be a nightmare for Geonet to try and figure out what's going on with the volcano. Sizable volcanic tremor then nothing and then the tremor comes back. Same with the quakes. Who's want to be a volcanologist?

jamie · Unread post by **jamie** » Mon 18/02/2013 08:47

yea shes cranking away again today. its the strongest and most consitant tremor to date. Small quakes occuring and the steam rising looks to me like its the biggest plume yet too.

jamie · Unread post by **jamie** » Tue 19/02/2013 08:29

i get the impression the little hybrid quakes are releasing energy. every time they start the level of the tremor decreases

tgsnoopy · Unread post by **tgsnoopy** » Fri 22/02/2013 07:33

I see seismic activity is still high, yet nothing further from IGNS re the activity. I can't help wondering if they will ultimately get caught short like they did with Tongariro reawakening.

Minor ash venting occurred today http://info.geonet.org.nz/pages/viewpag ... itter_News

11.30am and 1.30pm images show the minor ash emission:

And it settles back down again on the drum. Question is for how long?
