Are volcanos portals to hell?

Might as well be.

Sometimes. Into the medieval period, Mount Etna on Sicily was considered to be an entryway to hell.

No,

they are places where molten magma from a few miles down has found it's way to the surface.

Cheers!

No, of course not. Below volcanoes are magma chambers, and below that is the mantle. Below that is the liquid core and below that is the solid core. There's no hell on the way down.

I won't bother to dispute the existence of Hell, but I guarantee that volcanoes are not portals to it. They are places where Earth gives up heat from its formation.

Hell does not exist. It was thought up by perverse human minds to control people. Ergo, volcanoes cannot be the portal to hell.

No, it's the earth's idea of an orgasm.

No. No such thing.

I do not think so, they are just portals to hot magma well under the earth's surface.

Yes, but geysers are portals to heaven so it evens out.

Yes, in the same way that a cow with horns is a bicycle.
