re: #322 Teukka
Meh. Try Toba catastrophe theory. According to it, a VEI-8 eruption came very close to wipe our species out 75,000 years ago.
Krakatoa was a βmereβ VEI-6. Last VEI-7 we had was in 1816, a.k.a. βYear without a summerβ. And even a VEI-4 can pollute, see 1783 Laki eruption, it reeked so bad Frankling wrote about it.
Why do you know so much about earthquakes?
