Santorini could have provided all the fireworks, famines and etc. for the Exodus.
The Santinori plume would need to be 30 miles high to be visible in the Nile Valley. The recent Pinatubo volcano was 26 miles high.
The destroyed walls of Jerico are just above the Santorini ash layer and dated appropriately by charred wheat. (The Egyptian Kings List would have to be wrong)
It's just a idea, I absolutely do not want to get into another Lost Tribes discussion!!
