Would concrete even hold. I mean lava is molten rock and cement is kind of a rock. So wouldn't the cement melt before pressure could build up?

Most cements melt at a higher temperature than most lava gets to, so it would be solid chunks of cement getting blasted miles out when the pressure builds high enough to erupt

It probably wouldn't melt, but if you heat moist concrete it will spall ans crumble to bits before too long.

Yes. That's the joke.

Even if the plug would hold the volcano would just split open another hole in the earth and erupt from there

More job opportunities. Volcano hole filler would look great in my résumé.

And that would be a literal lava canon

Yes, there are many levels of stupid in this person’s proposal.

A depleted uranium cap with a "whistle" pressure release might just be what's needed to solve the issue though
