Don’t forget about Katmai 1912; approximately 2/3 of Krakatoa or 2x Pinatubo, and a rhyolitic eruption.

A volcano in southern Chile erupted with renewed vigor Tuesday, raining ash and lava over its surroundings and forcing a total evacuation in a 30-kilometer (19-mile) radius, the National Emergency Office said.
Emergency sirens sounded in the coastal region 1,300 kilometers (800 miles) south of Santiago, after the Chaiten volcano blasted out ash and cinders and generated lava and pyroclastic flows, four days after it awoke from a 300-year slumber.
“A maximum alert has been decreed,” Jorge Munoz, the head of the National Emergency Office (ONEMI), told AFP in Santiago after the volcano blew its top at 8:45am (1245 GMT).
A government vulcanologist warned that the eruption was only at the beginning stage and that an explosive eruption was possible.
“There could be a major explosion that could collapse the volcano’s cone,” said Luis Lara of the National Geologic and Mining Service.
Just beginning. Won’t affect northern hemisphere unless it blows Argentina to the moon.
Good point. Katmai was every bit an unknown as this Volcano. The caldera collapse at Katmai was very close to Pinatubo in explosive power - both a VEI 6.
