“Tuscany... is geothermally active, but we did not realize it contained such a large volume of magma, comparable to that of supervolcanic systems such as Yellowstone.”
INSUFFICIENT EVIDENCE
While claims 3, 4, and 5 establish the magma volume is comparable to supervolcanic systems like Yellowstone, this specific claim (index 8) lacks direct evidence linking the *volume* comparison to the source material provided for this index, as the evidence count is 0 and no web/wiki results were provided for this specific index.
