So you have a theory as to the cause of the Ten Plagues of Egypt?
Yes. They were caused by the 1628BC eruption of Thera. It also provided 'the staff by day and torch by night' mentioned in the bible. Ash and other derbis in Egypt have been chemically matched and dated to Thera. The plume would have had to be thirty miles high to have been seen in Egypt. Pinatuba (recent) in the Philippines was 26 miles high. It also provides the earthquakes/tidal waves for the parting of the Reed/Red Sea. (Mike Baillie speculates that a comet fragment may have initiated the Thera eruption and provided other fireworks in that period). Wouldn't something that drastic have been recorded in the bible, somewhere?
