The Mayan community was destroyed 1,590 years ago when a huge volcano erupted, a new study found a timeline using a major body of ice from Greenland, and the remains are filled from the event.
- For the first time in radiocarbon measurement, El Salvador’s Elopango volcano erupted on a large scale, with a magnitude of 431 A.D.
- The eruption was 50 times larger than Mount St. Helens
- He killed everything within 25 miles and extended the subsistence of that size twice for more than a century.
- An analysis of an ice core in Greenland confirmed the ash was carried more than 4,300 miles
- But that time is off to lead to the bizarre 18-month era of global cooling
Scientists have dated a catastrophic volcano that shook Mayan civilization thousands of years ago.
It has long been known that the Ilopango volcano, now in El Salvador, erupted between 300 and 600 during the early classic period of Mayans, but has yet to date a more precise date.
Archaeologists have unearthed a massive eruption in 431 AD, dating to radiocarbon on burning mahogany trees found in ash deposits.
To confirm their findings, the researchers measured the solution of the explosion plume using 3D modeling by climbing 28 miles into the atmosphere.
From there, the air currents carried him to Antarctica, more than 2,000 miles away.
An analysis of the ice core obtained in Greenland revealed the same chemical makeup, proving their hypothesis to be true – a violent eruption 1,590 years ago.

By radiocarbon dating to burning mahogany trees found in ash deposits, archaeologists have dated the eruption of Ilopango volcano in a few years to 431 AD.
Today, the Elopango Caldera is a pit lake less than six miles from modern-day San Salvador.
It is part of the El Salvador volcanic arc, a chain of 20 active volcanoes that is one of the most active in the Sismali active region of Central America.
About 1,600 years ago, this eruption reduced more than 70,070,000,000 square miles of white white ash in Central America, dubbed ‘Tierra Blanca Joven’ – the Spanish word for ‘young white earth.’
“It would have been dark in the area for at least a week,” said lead author Victoria Smith, an archaeologist at Oxford University.
The eruption left more than 770,000,000 square miles of white ashes in Central America, nicknamed ‘Tierra Blanca Joven’ – ‘Young White Earth’. Researchers estimate that its eruption increased 28 miles in the atmosphere above Plum
Tierra Blanca Joven was more than 50 times larger than Mount St. Helens in 1980, Smith added.
Its pyroclastic flow rate – the fast moving currents of gas, volcanic ash and pumice that can reach 1,830 ° F – was ten times that of the mount. Vesuvius when Pompeii was buried.
He cut off every living thing within 25 miles and gave the area a desolate size twice a century.
‘We think the lack of ceramic production in the general area is because people weren’t there,’ Smith told Ars Technica.
Tierra Blanca Joanne killed everything within 25 miles and devastated a century-two-to-two years. But Mayan culture survived, by that point it has already expanded into Central America
But it did not have a severe impact on the rest of the Mayan culture, which had already spread to Central America at the time.
Tierra Blanca Joven was found guilty of 18 months of global cooling by research published in 2019, reports Science Magazine.
But Smith’s research exploded more than a century ago.
Based on his team’s analysis, Tierra Blanca Jove probably lowered summer temperatures in the Southern Hemisphere for several years.
How can researchers do practical volcanic energy?
According to Eric Dunham, an associate professor of Earth, Energy and Environmental Sciences at Stanford University School, “Volcanoes are complex and there is currently no globally applicable means of predicting an eruption. In all likelihood, never will be. ‘
However, there are signs of an increase in volcanic activity, which researchers can use to help predict volcanic eruptions.
Researchers can track indicators such as:
- Volcanic infrasound: When a lava lake rises in an open vent volcanic crater, there is a sign of a potential eruption, while the pitch or frequency of the sounds produced by the magma increases.
- Seismic activity: Ahead of an eruption, seismic activity in the form of small earthquakes and tremors almost always increases as magma circulates through the volcanic ‘plumbing system’.
- Gas emissions: As the magma comes closer to the surface and the pressure decreases, the gases escape. Sulfur dioxide is one of the main constituents of volcanic gases, and an increase in it is an indication of an increasing amount of magma near the surface of the volcano.
- Ground deformation: A change in the surface of a volcano (volcanic deformation) that appears as swelling, sinking, or cracking, which can be caused by the movement of magma, gas, or other liquids (usually water) underground or by motion in the earth’s crust. Lines. Swelling of volcanic cans that have accumulated near the magma surface.
