Among many disasters on earth, volcanic eruption has never been a topic, because people pay more attention to earthquakes, tsunamis and floods than volcanic eruptions. Probably because people live far away from volcanoes, and most volcanoes in the world are hidden in the depths of the ocean. So such disasters are rarely taken to heart. However, if we really want to say a disaster that can destroy human civilization, then volcanic eruption must be one of them, because its energy is so great that it can even affect global climate change. It has brought extreme natural disasters, and studies have shown that Permian, Triassic and dinosaur extinction events. It is inseparable from the eruption of volcanic groups, and there have been large-scale volcanic eruptions in human history, and the scene of disaster is equally chilling.

Many people should know the magical "crying" of monks. In fact, regarding the distorted orange sky in the painting, some people think that it is not only a manifestation of inner fear and depression, but also a realistic scene related to an earth disaster. This disaster is the eruption of Krakato volcano, which is a volcano located on Lakata Island in Indonesian sunda strait. It broke out the biggest volcanic disaster in modern human history. It also caused the largest number of casualties. It even affected the climate of the whole earth, which may have inspired Monk at that time. Do you know what is going on?

It is necessary to do a little science on the level of volcanic eruption. The volcanic eruption levels are VEI0 to VEI8. Generally speaking, as long as it passes VEI4, the smoke column emitted by the volcano can exceed 10000 meters. It's like spitting out Mount Everest, which shows the horror of volcanic eruption. According to the research of geologists, there have VEI8 40 super volcanic eruptions on the earth so far. The most recent one was Taupo volcano 26,500 years ago, and the eruption of super volcano will also lead to mass extinction. There is no doubt that if VEI8 breaks out again. Human civilization is likely to be destroyed, and Krakato volcano is not a super volcano that can erupt VEI8 strictly. In 535 AD, it may have had a volcanic eruption with a magnitude of VEI7, and this volcanic eruption in 1883 was dozens of times less powerful than that one.

No, even intravenous injection. This is also one of the largest volcanic eruptions observed in human history. 1883 On August 27th, Krakato volcano in Indonesia experienced four violent explosions. The biggest one, the volcanic eruption level reached VEI6. According to the statistics of scientists, this explosion is equivalent to an energy explosion of 200 million TNT. That's 13000 times that of Hiroshima atomic bomb. Volcanic ash instantly sprayed to an altitude of 80 kilometers, covering an area of over 800,000 square kilometers.

Fortunately, it is far away from human settlements, so magma and volcanic ash did not cause a lot of casualties to human beings, but only led to the interruption of the route. Within three days, it was dark and no ship dared to cross.

Although volcanic cloud has not affected human beings, it has affected the whole earth. The first eruption of the volcano triggered a strong earthquake and tsunami, and two-thirds of Krakatoa disappeared in the explosion. Finally, a new volcanic cone was formed in the old crater, and together with it, a small island, Lakata Island, was formed. Surging energy set off a tsunami of more than 30 meters, which caused 165 coastal villages around Indonesia to be swallowed up and * * * 364 17 people died. If it weren't for the strait barrier, the disaster might be even greater.

The entry of volcanic ash into the climate has also led to spectacular orange-red sunsets in the sky around the world for several months. William Ascroft, a British painter, has created more than 500 paintings for this purpose, and Monk may have created The Scream. However, although it is beautiful, volcanic ash will filter out the solar radiation on the earth's surface, which will directly reduce the average summer temperature in the northern hemisphere by 65438 0.2 degrees Celsius in the following year.

In nature, every decrease in average climate 1 degree will bring about many drastic changes. Intuitively, it will cause species extinction. Fortunately, these volcanic ash substances did not last long. After 1888, the global climate returned to normal, which also brought this transformation of global ecology to an abrupt end.

In this volcanic eruption, the largest observable sound in human history was born. On the day of the outbreak, Australia, 3500 kilometers away, and Mauritius, 4800 kilometers away, all heard a loud noise. This is about 2.5 times the distance from Beijing to Guangzhou. If I tell you, the voice of Beijing can be heard in Guangzhou. Many people will think that you are dreaming. But in reality, even more absurd scenes may actually happen. Therefore, the disaster situation in the nearby 165 village can be imagined. Just the sound of volcanic eruption and infrasound waves that we can't see may kill many people on the spot.

This is the power of volcanic eruption, and it is only a VEI6 volcanic eruption. If a super volcano with a magnitude of VEI8 erupts in Wen Mingzhen, it will undoubtedly be an unprecedented disaster.
