Back in the 1990s, archaeologists have discovered a mass grave in the London area, which includes thousands of skeletons of the Middle Ages. At the time, scientists assumed that the combined mass grave of victims of the "black death" — bubonic plague, which in the XIV century, claimed the lives of at least 60 million people.
But recent research findings of scientists are pushing more and more to the conclusion that it was not a plague, and a huge volcanic eruption, which occurred a century before thousands of miles away, was the cause of death of the British.
This is confirmed by radiocarbon dating of bones and geological results from around the world. The eruption of a volcano in the middle of the XIII century, which is the largest in the last 10 thousand years, still remains one of the biggest mysteries in volcanology, changed the climate of the entire planet.
The consequences of the largest volcanic eruption
Cover of ice in Greenland and Antarctica, which dates from this time, contains a large amount of sulfur. Volcanic emissions in the upper atmosphere and their subsequent distribution throughout the world have led to the fact that the sunlight was reflected and reach the surface of the earth. This has led to a sharp cooling of the planet.
According to scientists, this is what caused the eruption of the "little ice age" that lasted until XIXveka — a period of abrupt cooling of the Earth. The history of this time and down full of references to rainy years and harsh winters, which led to crop failure, famine and other disasters.
Mexican volcano "El Chichon" Volcano "Quilotoa" in the Ecuadorian Andes or the volcano "Rinjani" on the island of Lombok in Indonesia? Surprisingly, the researchers still can not say with certainty exactly where the eruption, dating back to the year 1258. Current data indicate that the eruption is likely to happen in Indonesia.
Scientists conducted geochemical analysis of rocks of the mysterious volcano is fully consistent with the chemical analysis of sulfur on the pole. Species collected in the caldera of the volcano, well preserved after a large eruption. Computer modeling helps to suggest that the eruption of pumice soared into the air to a height of more than 40 kilometers away, swept away the remnants of rocks tens of kilometers around.
One of the monks who lived in the XIII century, left the following lines of that period: "The north wind prevailed for several months … countless poor people were killed, their bodies swollen from want … especially great pestilence was in London, where he took about 15 thousands of lives. "
Effect of sulfur on the human body
It is known that inhalation of hydrogen sulfide causes seizures, the person loses consciousness and stops breathing. If he is still alive, it may become disabled — with paralysis, mental disorders, lung function and gastrointestinal tract.
Experts believe that the excessive intake of sulfur in the body in recent years have increased significantly — in food sulfate is added to extend their shelf life. Most of them in smoked foods, ready-made salads, beer, wine and painted in vinegar.
