One of the theories is that that a string of volcano in Siberia erupted for 10,000 years raising the earths temperature by over 5 degrees, causing land based life to suffocate and ocean based creatures to not be able to breath.
I also read up on the Yellow stone eruption that happened 650,000 years ago that flung 1000 cubic kilometres of rock and ash into low earth orbit. it is estimated that the explosion measured at 875,000 megatons.

That extinction event would be at the Permian and Triassic, not Jurassic. Regarding volcanoes locally, we are in a time where there likely will be some incredible activity. Both Yellowstone and the Great Rift (Craters of the Moons area) are in a timeframe where they should be ready to blow.
