What happens if 1500 volcanoes on Earth erupt

If 1,500 volcanoes are active all over the world erupting at the same time, disaster can cause humanity to fall into the end of the world.

According to Flash Forward, Earth currently has 1,500 active volcanoes. These are volcanoes that erupted at least once during the last 10,000 years. This figure does not include the volcanic belt that continues continuously on the ocean floor with about 500 volcanoes erupting in history. However, not every eruption is the same.

"You can set up eruptions in two groups. The first group produces lava and many gas streams called " effusive "(overflow). The second group produces ash and gas named " explosive. "(booming) . The difference in the eruption activity is mainly due to the viscosity of magma (the slate) . The more viscous magmatic rocks are, the harder it is to release the gas and the higher the probability of an explosion," said Dr. Matthew Watson, Volcanic expert at the University of Bristol, UK, said.

Although the eruptions may be different, if all volcanoes on Earth operate at the same time, the consequences will be very serious.

Preliminary damage in areas near volcanoes

Residents living in volcanic eruptions are not only affected by magma currents but also giant ash clouds.Pyroclastic flow is a cloud of rock, ash, gas that moves quickly and very hot at temperatures up to 1,000 ° C. They can move at 724km / h, so almost no one can escape. Not only affecting residents living nearby, but also the lava flows can cause damage in a 160km radius around the volcano.

Extensive damage

Columns of ash from eruptions can reach thousands of kilometers."The ash is not very pleasant. They include small pieces of glass, crystal and soil , " Dr. Watson said.

Not only are they capable of destroying aircraft engines, dense volcanic ash can collapse buildings as they build up and gradually nail down houses. Inhaling ash can lead to serious problems with the lungs, including pneumoconiosis.

People cannot walk without wearing a gas mask. In addition, the communication channels will stop working due to ash disrupting satellite operation and blocking radio waves.

Climate change in the long term

Volcanic eruptions may entail long-term changes to the Earth's climate. In fact, the huge amount of ash and gas released from the crater will lower global temperatures.

"The sudden increase in sulfur dioxide levels causes the formation of small particles called aerosols when exposed to water, reflecting sunlight backwards. This process will make the planet cooler, even creating ice ages. Little " , Dr. Watson shared.

However, over a longer period of time, humans may experience the opposite effect of rising temperatures."After hundreds of years, volcanic carbon dioxide (CO ₂ ) will warm up the planet , " Dr. Watson warned.
