I'm wondering if it is technically possible to stop pyroclastic flows from volcanoes (particularly ones near population centers like vesuivious) by building barriers and if so if its an efficient use of resources. Not quite world changing but it is still a low risk and high impact issue and there are US cities that are near volcanoes.

I'm sure someone has thought of this before and done some analysis.
