Okay, I'm reading Cline's 1177 now, and am checking up references as I do so.
He's just mentioned the Santorini eruption, dated to somewhere around 1600-1500 BC, so I checked up the Hekla 3 eruption - which is going to be blamed as a major cause for the collapse of Bronze Age civilizations.
The first problem is that Wikipedia doesn't mention Hekla 3 in its list of
biggest volcanic events in history, certainly not from around 1100BC. Additionally, there's a massive degree in magnitude between the two eruptions:
Hekla 3:
circa 1100BC
Volcanic Explosive Index of 5
7.3 cubic km of rock thrown into the atmosphere.
Effect on the world: cooled the northern hemisphere for several years afterwards, causing significant climate change that resulted in the collapse of civilizations around the world
Santorini eruption:
circe 1600BC
Volcanic Explosive Index of 7
60 cubic km of rock thrown into the atmosphere.
Effect on the world: some impact on the local Minoan civilization
I'm already left scratching my head here - if the Santorini eruption is one of the biggest ever recorded in written history, and was local to the Aegean, then how come an eruption near the Arctic Circle that was ten times smaller cause worse damage?
Also, my reading is that there was major climate change in Britain around 800BC, but there are no major volcanic events associated with that.
The implication is that if a volcanic eruption is the smoking gun for climate change leading to Bronze Age collapse in the Mediterranean, then there had to be something specifically significant about the smaller eruption much further away.
Alternatively, the eruptions had irrelevant to minor effects on climate change, so that volcanic eruptions are not a smoking gun but a red herring.
I'm also left wondering just how reliable ancient dating currently is - I'm increasingly getting the impression that something is very off-kilter, especially if the Hekla 3 eruption can be blamed for collapse of Mediterranean civilizations around 1100BC, but Northern Europe not be affected by climate change until around 800BC.
Hmm. Just thinking aloud.
