As far as I know, large voids likely don't form in magma chambers. Maybe in some that are only a few hundred metres underground, like in Þríhnúkagígur in Iceland, but those are really magma conduits, rather than magma chambers. The pressures involved in the crust er likely to collapse any significantly large voids, especially considering that the rock around magma chambers is hot and ductile and not exactly load bearing. Plus most magma chambers have a huge footprint, so the roof would have to support an immense weight of crust to sustain a large void. However, exsolved gas can accumulate and probably form rather large high pressure pockets of gas in some more viscous melts.
@patrickgriffiths889

The magma breaks rock and makes room, hence the associated ground deformation and earthquakes. It's basically nature's fracking (only way more powerful than anything humans do). Also, it takes a LONG time for magma to cool, so fresh hot magma will bring heat that re-melts the older rock & magma slush in the cooling chamber.

Another question... does water coming back at the river right before Hekla goes off has the same composition as what's normally flowing during calm periods? The flow resuming may not be to water from the main fault flowing back to the spring, but it may be water squeezed out of the aquifers as pressure increases further. This water having sat for a long time into the volcano could have picked up sulfur, clay or whatnot and become murky and stinky. Historical accounts often talk about wells drying up and then filling with "tainted" water right before Vesuvius erupts.

One way of determining if this 'circumstantial evidence' is a reliable precursor is to monitor the volcano, and specifically, this river and its flow, for a set period of time and chart all its changes. Does it always dry up before an eruption? Does it start flowing just prior to the volcano erupting? Does it ever dry up for other reasons? Does it ever keep flowing despite the volcano becoming active again? What is the longest time it has been dry for before Hekla erupts? How soon after water returns does Hekla erupt? Predicting when a volcano will erupt is well nigh impossible, but forecasting, whilst difficult, isn't. Nevertheless, it is still impossible to say 'X volcano will erupt in Y time'... unless, of course, there is some kind of precursor event that is reliable, this being the crucial factor. If the flow of this river is reliable, then we may have that precursor event at Hekla. There may be other small but tell-tale events at other volcanoes, too. The drive way fumarole at Mauna Loa is a prime example of this: something small and localised, but happens like clockwork just before an eruption. I suspect that many volcanoes have something like this, but often so small no one has ever noticed them before. The issue then is just how long of an interval between the phenomenon occurring and the start of an eruption. Whilst such a precursor event occurring years before the eruption isn't a lot of help, at least people will know the volcano is primed to go. At the other end, something that happens mere minutes before an eruption starts is of no use to anyone, since it just doesn't give enough of a warning to do anything. Nevertheless, if many dangerous volcanoes do have these little tell tale signs hidden in plain sight, then perhaps the best thing we can do is go look for them, test their reliability, and if they do prove to be an accurate guide, start monitoring them!

Interesting I have heard that Hekla is a worrying volcano because of how little warning it gives. If uplift is the driver shouldn't GPS sensors or satellite fly over interferometry fringe cross comparisons be able to pick up the deformation? Do we know if the area in question has received more or less precipitation than usual? Those seem to be the main additional factors that comes to mind to check if this river drying up is volcanic in origin. From what I have read one of the curious things for Hekla other than the rapid rate of ascent is that its eruptions tend o start as rhyolite and evolve to more mafic compositions i.e. rhyolite dacite andesite to basalt. Not sure how accurate that is but if true it would suggest serious crystal fractionalization and differentiation occurs within its magma chamber.

When a volcano erupts and forms a cone, does the surrounding area sink down?
@LuisAldamiz
13 күн бұрын
The cone is created by the materials from the eruptions (usually one after the other, many eruptions). This is obviously coming from below but AFAIK, generally speaking, because of the increased magma/gas pressure preceding the eruption and because of empty magma chambers (caves), it does not necessarily mean that the surrounding area sinks. That probably depends on other factors and is more likely to happen maybe in explosive highly destructive eruptions, caldera style, of the kind that destroy rather than form a cone. Not an expert anyhow. Double check yourself.
@iceboi5983
13 күн бұрын
Generally, yes. When you move stuff from below or inside the crust to above the crust, it sinks / subsides in response to that lost volume. However most volcanic eruptions are also associated with inflation (crust rising) when magma moves up in the crust from deeper down. Also the subsided area does not necessarily have to concide with where the magma reaches the surface, just with where the magma is draining from. Subsidence has been observed numerous times during volcanic eruptions using geodetic methods such as GPS, InSAR (satellite radar), tiltmeters, etc. Usually the amount of subsidence is very little, maybe only a few centimetres spread over a large area. However in eruptions where a magma chamber is reduced in volume by a significant amount, the crust above it can collapse and subside by hundreds of metres, forming huge sinkholes called calderas. But those types of eruptions are not common.

Far from all the experts claimed this. Volcanology is hard and no volcanic system is really alike even if they have many similarities. Not to mention many systems changes as the grow older. These experts are doing their job saying out loud what their life long research tells them. No science is anywhere near complete. If it was there wouldn't be much fascination left. This is just a fair warning not too do any unnecessary mountain climbing on the close proximity in the near future and blame lack of warnings if injuries or deaths happens. Also a warning too any potential Lahar drainage's too be a little extra aware. Think the people that suffer injuries from ignoring warnings from St.helens would tell people too stay a few Kilometers away or be ready to leave quick. But Iceland are pros at this after good practice in Grindavik.
