The impact of a volcanic eruption to prehistoric Scotland
Alistair Moffat, author of Before Scotland, has no doubt that when Hekla blew, the west coast inhabitants must have heard the boom and panicked. Moffat thinks they would have been in no doubt that the god’s were angry. The eruption would have been heralded with ferocious electrical storms and the weather would have changed.
