Jun 21, 2024: Fighting Lava with Water at Breached Berm, Iceland

- Lava is currently breaching the northern berm that is protecting the Blue Lagoon and the Svartsengi power station. Local firefighting and berm crews are working to contain the lava with water and new berms.
This camera is situated on the southern tip of Þorbjörn. Þorbjörn is a 243 m high volcanic mountain next to the town of Grindavík.
Looks like if they can raise the newest side walls they can create a mini lava pond where it can accumulate and cool. Still curious when we will get new topographical maps since the lava has changed much of the landscape for future lava flows.
"they're gonna need a bigger boat"
seems this is a productive as me trying to raise the level of a local lake, by taking a P.. I have seen other video, where a half dozen fire boats used water to prevent lava from closing a harbor entrance.. I don't recall if it worked or not..
They were not trying to stop the lava..just cooling the encroaching edges to buy time for the berm workers to reinforce berms
@@repyep2314 a distinction with little difference
They are trying to stop the lava, long enough to add to the berm to stop the lava.
Is that better?
This specific eruption is now over so they have done what they were intending.Trying to stop this excess from reaching the power plant
@@repyep2314 yeah my comment is from 2 hours ago, it is really interesting how it all happens, and how quickly things can change..
Cheers
Right?!! I've watching this herculean demonstration of hubris!
Hopefully the seawater will cool the front of the lava flow enough so that it becomes a dam. Wonder if Icelanders will ultimately be successful in directing the lava elsewhere?
Is it sea water?
@@MikeGreenwood51 hopefully not as that would cause a lot of toxic gasses to be released
@@ishmyboy While dry salts in saltwater won't decompose at the temperature of lava they will to a low extent in the presence of steam, and may react with the lava, but recombine rapidly rather than exist as toxic gas in large quantities. There is already relatively high levels of toxic gas in the area.
Just don't get downwind of the highly energetic chemical cocktail.
It takes approximately 3kg of water to cool 1kg of lava from molten to solid, it still remains hot then but is solidified to rock.
With a wide latitude 1kg/1 litre of water will solidify approximately half to 3/4 a litre of lava depending on the gas inclusion rate. Some lava can be comparatively quite light and fluffy.
Then a lot of the additional water will be 'wasted' cooling hot but solid rock rather than solidifying lava.
With some very wide parameters the hose may be discharging 50 litres per second and solidifying 1 cubic meter of lava per minute. Which is tiny compared to the bulk of the lava field but enough to form a plug/wall in a small lava leak as shown here over an hour.
Also I need to get a life :-)
Is it getting bad?
yes, this lava flow is threatening the power plant more than any previous one
Was soll das bringen 😅😂
If they stop the lava there nearer the defense wall the newly cooled lava may help to creat a barrier to the main flow on the other side of the wall.
