And a crap load of co2 where are th environmentalist protesting the eruptions or carbon taxing it (sarcasm)
Volcanoes of all types, on average, emit somewhere in the ballpark of 645 million tons of CO2 per year, with occasional large eruptions adding tens or possibly even a hundred million tons to that total.
The one thing I remember about Mt St Helens eruption all the way here in Oklahoma was the ash. We had issues keeping our vehicle air filters clean. I’m guessing the same with AC/Heater house as well.
The closer you are the more it’ll contaminate such as water supplies.
