We all know about the ring of fire, and we all know what happens when a volcano erupts.
For context: this is set in the near future, with humans living in high-tech protective domes during/following the catastrophic eruptions.
My question is: say the ring of fire finally erupts, leading to a domino effect with most of the active or dormant volcanos erupting, just how bad would the toxic gas, ash, earthquakes, etc. affect the world in the long term?
I realize large portions of the ecosystem would die from a combination of toxic gas, acid rain, and ash clouding the sun. But I'm curious how quickly the earth would recover using more adaptable species and plants such as kudzu and bamboo (or other fast growing plants).
Edit: Thank you everyone for informing me that the ring of fire would never actually all erupt at once, however, i'm not concerned with the hard science of an eruption, this work will take liberties with science and is more soft scifi. I just wanted a quick overview of what the world post eruption would be like.
