I don't have such a hard time believing that magma under enormous pressure, and being much hotter than the atmosphere, would have the capability of expanding at a speed that would be supersonic for the atmosphere.
I'll re-run my wetware simulations Charles, maybe I missed something.
I "think" that the only answer is ohmic heating from an electric current.
Electricity is in there for sure, and ohmic heating to a point, but there is another process involved I believe, but not sure just what at present.

The creation of the Vuoksi River preceded a significant cultural shift

After the end of the last ice age, post-glacial rebound caused the Earth's crust in eastern Fenno-Scandinavia to tilt, increasing the amount of water and size of the body of water that would later become Lake Saimaa. Approximately 6,000 years ago, the Salpausselkä ridge could no longer hold back the waters, which burst through and penetrated the glacial till and bedrock with incredible force. This created the Vuoksi River, and resulted in an approximately four-metre decrease in the water level of Lake Saimaa, revealing thousands of square kilometres of new land in Eastern Finland.
Imatra rapids show, Finland.
In my mind, this is a beautiful example of a discharge track having torn out the bedrock and forming the rapids. Regardless of how much water flow goes down the rapids, the rocks, other than the fines, do not move, and never have. I see exactly the same thing in my neck of the woods.
Post glacial rebound is an accepted, by mainstream geologists, process used to account for what they see now, but to me is another nonsense idea. How does a 5 mile deep (another presumption) layer of ice push down many miles of layered solid rock strata, whos natural shape is of many segments of arch, and we know just how strong arches can be. The strength of just an egg shell demonstrates just how much pressure can be applied before the shell breaks, so to think that miles of ice could press push down the Earths surface is, IMO, preposterous.
That the Earths surface or ocean bed has and still does rise and fall now and then, sometimes thousands of feet in a relatively short time, can not be denied, and has been recounted in legends from around the world. Plato and Atlantis is perhaps one of the better known accounts, and even the Bible tells of such catastrophic events. Some geologists who studied the reading of Edgar Cayce as regarding Earth changes went out and confirmed that indeed such changes had occurred, at the locations and within the time frames specified by Cayce. What seems to be common to all these changes is that the change was in altitude, not in horizontal position, so if "what was high becomes low, and what was low becomes high", then there may have been apparent horizontal movement when comparing before and after geography of Earth, but not actual horizontal movement.
The forces that cause such huge and rapid changes can not be from the processes favoured by standard geological models, and are most likely to be from electromagnetic processes as yet unrecognised and not understood even by EU catastrophists, and according to Cayce, the changes, including tilting of the Earths axis, must be seen to coincide with the Earths relationship to some of the other planets, Saturn and Venus in particular.
So some catastrophic events may result in the end of life on Earth, but Cayce also reminds us that life is "of the spirit", and as with Psalm 46 from the Bible, that we should not be fearful.
1 God is our refuge and strength, a very present help in trouble.
2 Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea;
3 Though the waters thereof roar and be troubled, though the mountains shake with the swelling thereof. Selah.
And that concludes my sermon for today.
