    I live about 30 minutes away. We’ve had a lot of earthquakes the past few days. This should shut them up :) Some scientists say we’ve entered a period of very frequent volcanic activity for the next 100 years or so in this area.

      Ahh yes just what we need. More toxic gases being vented into the atmosphere. I’m sure it will be fine.

              Maybe, maybe not. Fire triangle is heat, fuel, oxygen.

              We can assume safely fuel and heat, oxygen is tricky though.

              Explosions and ignitions only happen in a happy zone.

              Too much or too little oxygen disables everything.

              We also have to calculate what mix of hydrocarbons we are dealing with, how hot the ignition points are and the pressure exerted by gravity and the atmosphere.

              I don’t think there is enough oxygen.

              Even under ideal circumstances and distribution, there is still only 21% oxygen in the air.

              Propane needs 8x the amount of oxygen for a complete burn as acetylene does and acetylene in open air just produces thick greasy black strings in the air.

              Idk the exact mix but I know you can barely hear acetylene coming out of a torch, but the oxygen side is loud as fuck.

              Given a reasonable variance for imprecision, I feel the variance in sound levels is proportional to gas flow.

              However depending on the pressure, you could need even more.

              Diesel fuel is damn near impossible to light on fire at SPT, but put it under compression and it will self ignite.

              We use turbos, basically little air compressors, to force as much regular air as possible into an engine, because it uses so much oxygen.

        There’s actually a lot of small mineral dust that are sent in the air, that can filter some sun rays and decrease the heat

        These ones cool stuff in the short term (and cause acid rain, ozone depletion, famines and long term warming; and there’ll probably be a new thing this time around where some countries have reduced solar output).

        They also ground planes and cancel road trips.

        This volcano might even save us from a blue arctic event for a few extra years, so it could be a wash in terms of climate (although definitely not for europe’s ability to feed itself)

      I don’t mean to steal attention away from Iceland and hope you are all safe, but it’s a similar thing in Japan. We’re due for a megathrust earthquake that could be way way worse than Fukushima.
