What would happen if all the volcanoes on Earth erupted at the same time?
Volcano

Up to 20 volcanoes erupt every day on Earth. But what would happen if every volcano on Earth erupted simultaneously? Will the Earth as we know it survive? Scientists say that the chance of each volcano erupting at once is so small as to be impossible.

But what if…?

Two major dangers from a worldwide volcanic cataclysm are ash and gases. (While eruptions and lava flows would be deadly to people living near the volcano.)

A thick layer of ash would cover the Earth completely, blocking the penetration of sunlight. The planet would be plunged into total darkness, photosynthesis would be devastated, crops would be destroyed, and temperatures would drop dramatically – dominating the atmosphere for up to 10 years.

Acid rain would wipe out any crops that survived the ash cover. Volcanic gases containing hydrochloric acid, hydrogen sulfide, and sulfur dioxide would turn into acid rain as they rose high into the atmosphere. Then this rain would contaminate underground springs and surface ocean waters – corals and sea creatures would be killed, extinctions would include fish and other sea life.

A similar link has been documented between ocean acidification, mass extinctions and volcanic floods. For example, these mega-floods have occurred 3 times in Earth's history; 252 million years ago; 201 million years ago; and 65 million years ago.

But what could survive the deadly volcanic eruption?

Scientists say this would usher in the age of extremophiles, organisms that already live in extremely acidic environments

A sci-fi strategy is also possible: some people would live in deep underground bunkers built by governments and funded by wealthy billionaires, waiting for the atmosphere to clear - in this scenario, the dead would be the most lucky.
