[rmcarddy] Supervolcano 2

A sequel to the 2005 made-for-TV movie:

Yellowstone doesn't stop.  It transitions to shield volcanism and keeps erupting, off and on, for centuries, covering a good chunk North America in flood basalt a mile thick.  The same volcanic hotspot has already done this in the past (Columbia River Basalt Group).

Mass extinction happens, as has happened before in similar eruptions such as the Deccan Traps and Siberian Traps.

Notes: Large Igneous Province.
Laki was an effusive eruption in modern times in Iceland that caused suffering throughout the world.
