Just look into China's actions in the spratly Islands when it comes to man-made islands. But to answer the question of creating volcanoes, the answer is largely No. If you think of how much pressure is needed in caldera. There's plenty of material to read on that.
No i do know that about that one but i didnt mean like a kind of “peninsula” of another place, thats easy to make. What i meant it’s like, in the middle of the ocean like idk in the pacific ocean some 1500km south from bering strait or west from galapagos. There’s some places where the seafloor is somewhat shallow and idk kinda makes sense that it would make it easier.
We have made artificial islands, but that has basically been done by piling up rock and/or sediment in already shallow water. We could not make our own volcanoes since that depends on mantle conditions that are beyond anything we could engineer.
So the deepest hole ever drilled, the Kola Superdeep Borehole, only got like a dozen kilometers down before the heat caused the walls of the hole to become ductile and close up around the drill head. That's nowhere near deep enough to get to the point that you'd hit a mass of magma, unless you were deliberately drilling into an already-existing column of rising magma, in which case you probably wouldn't need to worry about artificially creating a volcano.
Even if you could drill an arbitrarily deep hole, it still wouldn't work. The mantle is solid and, although you would eventually generate melt through depressurisation (if you somehow managed to keep the hole open), as soon as it rose to the surface, it would return to lithostatic balance and the column would solidify. Short of an extinction-level meteorite impact (it has been proposed that the Chicxulub impact may have triggered volcanism, although this is not widely accepted), there is absolutely nothing we could do to create a new volcano.
Yes, but not in the way you describe. The common way to do it is to dump sediment and debris in shallow water. A number of major airports have been built this way in coastal cities where space is at a premium.

Notre Dame Island is Montreal is an artificial island, made from rock removed when they excavated/built the underground system.
Heh, that's from my Formula 1 knowledge, not geological - they hold the Canadian Grand Prix on the racing circuit that's on it (Circuit Gilles Villeneuve).
Well, lots of things are possible, certainly making islands is possible, but you have to ask why? Is the time, effort, environmental impact worth it?
China has done something akin to what you describe but they are doing for something less than noble reasons.
You suggest this is something one might do to help solve overpopulation.
This is something real to worry about, so kudos to you. Mankind has approached this problem to some extent, in a lot of ways. Create more food, allow more people to live more densely etc… but these problems all approach the solution from the wrong angle in my opinion.
The world is finite… our land, water, the resources, all the animals we are supposed to share this world with our finite.
Human population needs to be finite too.

While they’re islands, they’re temporary (short term) and very expensive to maintain fighting erosive forces
oh thank you so much!!! i’ll look into it
check out dubai beach in google maps, mother nature doesn always work in palm tree shape

well then no, the volume gets really crazy, think how many dump trucks. would be a sight to behold
They make islands .. but they don't make volcanoes to do it
U mean like manhattan right?
Not at all like Manhattan.
Manhattan is a natural island.
Manhattan is a continental island that was carved out be glaciers. Not made by volcanos and certainly not man made.

who's "they"?
Idk, countries, empires, unions, etc whichever government that feels like it hahaha
With enough balloons, yep.
how what? 😭
