Sounds to me as though the vent has closed slightly. Earth quakes are a sign pressure is building aren’t they?

Hard to say. Volcanic quakes can often be caused by shallow movement of fluid e.g. magma breaking rock or hydrothermal pressure as well.

Alert level lowered to 1 after activity has decreased

Tremor continues to be quite strong, even more so since this afternoon

At times, what is the wind like needs to be considered with Ruapehu. The seismographs on Mt. Ruapehu have the solar panel poles close and they aren't deep in the rocky environment. This isn't one of those times! I hope it doesn't ruin the season, they've just endured two COVID years.

there is not strong enough wind currently to cause this ?

jamie · Unread post by **jamie** » Sun 03/04/2022 19:14

Yea that’s what David is saying Brian. Wind is not one of these times. It certainly is humming inside. Would not be supposed in the slightest to hear of a ruapehu fart while it’s behaving like this.

my Daughter did the Tongariro crossing today..perfect weather...got sun burnt even
she was a bit worried about the alert level

Do we think that is wind noise showing up on the far west drum now or another increase in volcanic tremor over the past few hours (particularly the last hour and a half)?

Could be a bit of both. Interesting none the less.

Looks like tremor to me. Certainly not as strong as a few days back though.

Latest bulletin says they measured the second highest CO2 readings they’ve ever seen at Ruapehu and interred that activity is being driven by shallow magma

Geonet update indicates possible blockage of the vent and increasing pressure build up as crater lake temps have stabilised yet strong volcanic tremor and gas input continue. Will be interesting to see what comes of this over the next wee while..

I thinl I read somewhere (not sure where) that this type of situation can lead to a single vent clearing burp (if anything) such as 2007, rather than ongoing larger eruptions, which are usually preceeded by sustained very hot lake temps (>50 degrees)? Anyone heard something along these lines before?

Interesting to see quite a sharp decline in tremor this afternoon

Not for long it seems.

Yeah has happened twice the last couple of days. Dropped of a cliff all of a sudden then come back as strong as ever. Very interesting..

Horizons still have 2 webcams in operation at Tangiwai that you may want to bookmark just in does it does blow during the day:

And one at Tukino (though not sure if that one is updating - the other 2 certainly are):

There are some great photos from the 2007 eruption here:

I can remember hearing reports it was erupting, and watched the river level rapidly rise as the lahar swept past via those webcams.

Looks like he may be letting off puffs of steam on the Geonet and skifield cams

not steam like you would think , but instead the lake is so warm now (39c, which is like a spa pool),its creating cloud in the cooler air
Geonet should not technically be calling it steam (steam is from boiling water...steam is a phase of water..instead its water vapour evaporated off the warm lake that has then condensed into clouds)
unless there is actually boiling water at the bottom of the lake now, and steam bubbles are rising to the surface?

Thanks Brian. After the initial excitement when I checked the cams I figured as much when the general cloud cover around the volcano kept increasing.

Another degree of temperature rise in a day is pretty good going. Looks like the upwelling of the central vent is in full swing. Whether it will be enough to release the pressure and stop an eruption remains to be seen. I'm unconvinced.. Think it will go boom at some point in the near future.

its obviously had lots of big eruptions in its past..otherwise it wouldn't exist..i.e there will be more big eruptions in the future, and our monitoring time period is so short compared to how long the volcanoe has been erupting...yes? ( which is 200,000 years..just looked that up)
