Just a retard asking a question here-- could the town have been protected by a rampart and ditch for redirecting lava flow?

Not asking if it's economical, just a geology question.

In theory, I suppose it's not impossible. In practice though, no. You'd be redirecting hundreds of square Km of lava with little forewarning, so hot it would burn through just about any levy with the added difficulty of lava cooling, solidifying and building on itself eventually getting over any trench or wall.
 
You would have to have alot of information like where the volcano would appear, you need an army of engineers with explosives to blast through rock and a bulldozer fleet to create a channel quickly.

And most of all they would have to work faster than the volcano

You could...but its cheaper to just let the lava flow through town

Yeah, I was just wondering if it would work. It's clearly not practical.

In theory yes. But not like in "Volcano" about the eruption is LA which was comical.

However this depends on the lava flow. A VEI4 is a stretch, for a VEI5 or larger forget about it. Too much lava probably. Dirt is fine to use.

Also, just remember that as with La Palma, other vents do tend to spring up so your levy may be in the wrong place after the eruption starts.

And, a Levy would typically need to be on a hill (most volcanoes are sloped including their cities), so there is a danger that what you create turns into a dam and then bursts causing even more damage.

In theory it works. The better solution is don't build near a volcano - easy to say, harder to do in reality as they generally offer rich fertile grounds for crops so tend to get populated. They also provide elevation and protection from elements (except eruption).

Here's hoping La Palma gets out of this relatively unscathed and bounces back. I'd love to try their volcano-infused bananas

You just know some woonatics are going to get on that bandwagon. “We only eat volcano-infused bananas from the island of La Palma!” Oh well, at least the farmers will make money.

I think Matt is going to request a raise.

Drone footage of the lava platform taken this morning. The new delta already measures 36 hectares, and a part of the lava river has separated from the main one and it is expected to reach the ocean soon.

It looks like the new lava flow is actually hitting the land created by the 1949 eruption. Interesting.

There have been 92 earthquakes in the past 24 hours, the largest was 4.3M represented by the largest red circle on the right.
(Yellow: current eruption. Blue: 1949 eruption)

Its all along the faultline that wants to slip and create the tsunami :stress:

400 million euros in damages sure is cheap.
 
Wow, I was watching it and all of a sudden something happened (collapse? idk proper volcano terminology) and then the whole area was flooded with lava. The fattest lava flow I've seen so far and it's really lighting up the sky. Now the live stream isn't working.

edit: Stream seems to be working again. Now it's hard to see what's going on.

Wow, definitely thin and fast moving lava.
Also loving the chat mods nuking any mention of tsunamis.

Eta: apparently all streams have stopped working.

The other problem is Lava is not water. It doesn’t behave like water. As it flows the outer portions of it are cooling, adhering to the landscape and will eventually build up enough to cause the lava flow to shift in a largely unpredictable way. I mean you could probably lay down some Highway barriers to channel it temporarily, if you can clearly see it’s coming. It might buy enough time to get some things out of harms way? But it would be very temporary.
 
Found some more great drone footage of the lava flow spilling into the sea. It was posted today, 10/7. Pretty sure no one has posted it here yet. Here is the YouTube Link. Embedded the same footage below.
