10 Things That Would Happen if Every Volcano on Earth Erupted at Once
Communication and travel would cease
Ash clouds wouldn’t just block out the sun, they would hinder nearly all forms of telecommunications as it would reduce the strength of radio and satellite signals and damage equipment. The volcanic ash would clog the cooling systems many electronic devices require to operate and cause them to overheat.
Air travel would also be out of the question. In 2010, the Eyjafjallajökull eruption in Iceland led to the most far-reaching air travel shut down since World War II. Volcanic ash, which is comprised of glass and rock particles, can travel far enough into the air to reach jet altitude and can cause extensive damage to aircrafts and even cause their engines to stall.
Much like airplane engines, car engines would also be clogged with ash – and let’s not forget how hard it was for Pierce Brosnan to drive through lava in Dante’s Peak.
