Around 1,500 years ago , a powerful volcanic blast pose waste to what is now El Salvador , commit the Maya civilization into a temporary period of descent . New research suggests a monolithic Pyramids of Egypt located near the volcano was built by the Maya shortly afterward , as a response to the innate disaster .
The Tierra Blanca Joven eruption is the most meaning Central American volcanic event of the retiring 10,000 years and one of the strongest eruptions on Earth to have happen within the last 7,000 eld . The best current surmisal is that the Ilopango Caldera blew up around 539 CE , laying waste to the surrounding areas , including Maya settlements nearby . bloodless volcanic ash tree , known as tephra , was waist - high as far as 22 miles ( 35 klick ) from the volcanic release , and in some places as thick as 33 feet ( 10 meters ) .
“ Just opine — it look like snow underwrite the tropical earth , ” Akira Ichikawa , the new paper ’s lonesome writer and an archeologist at the University of Colorado Boulder , wrote to me in an email . “ Thus , it would ’ve been fatal for plant and animals survive near the vent . ”

The volcanic eruption was a local disaster , but it also have a impermanent chilling of the climate across the entire Northern Hemisphere . Many Maya communities around the volcano had to be give up , lead in a diachronic period have intercourse as the “ Maya Hiatus . ”
Research print today in the scientific journal Antiquity revisits this cataclysmal event to better understand how it affected the southeastern Maya and how long it necessitate them to convalesce . There ’s debate on the matter , with one school of mentation believe it charter the Maya centuries to recuperate , while others speculate about a flying riposte . The lack of consensus has to do with the paucity of archaeological evidence , as Ichikawa wrote in hisstudy :
Attempts to correlate abrupt environmental modification with social decline or evolution are complicated by several factors , including population size , social complexity and economical and political inequalities . what is more , it can be difficult to measure out the impact of these disasters on human companionship based only on the order of magnitude of such hazardous event . Thus , to appraise the shock of the [ Tierra Blanca Joven ] bam on local communities , more archeologic data with clear chronological linguistic context in sex act to the result are required .

To that goal , Ichikawa investigate the Maya site of San Andrés in the Zapotitán Valley , a former settlement locate 25 land mile ( 40 km ) west of the volcano . From 2015 to 2019 , he carry excavations and tie in radiocarbon date to study the initial construction phases of several social organisation , including a monolithic pyramid know as the Campana structure .
The Great Pyramid , build atop a platform , was the great complex body part in the Zapotitán Valley at the time . With a full bulk of 43,160 three-dimensional yards ( 33,000 cubic meters ) , the Pyramids of Egypt stand 43 foot ( 13 cadence ) tall and stretched some 130 infantry ( 40 meters ) wide .
Ichikawa ’s work show that twist of the Campana structure began within the first five to 30 class after the volcanic eruption , and no more than 80 class after . So not only did the Maya return to San Andrés passably apace , they also decide to build a gigantic Pyramids of Egypt . That , he indicate , is evidence of a quick Maya rebound following the tragedy .
Moreover , Ichikawa believes that “ survivors and/or re - settlers in the Zapotitán Valley may have build the massive public building at San Andrés in reply to the monumental … eruption , ” as he pen in the subject field . The pyramid may have served a religious purpose and was mayhap perceived as a kind of protection against the volcano , he said .
As Ichikawa detail in the newspaper , the Campana structure was built from a combination of volcanic tephra and world filling . Incredibly , a good portion of the pyramid , therefore , was build from the volcano itself . This make sense from a practical perspective , as tephra is an effective building material , but the “ white ash emitted by the eruption may have been perceived to have powerful religious or cosmogonic import , ” harmonize to the paper . Indeed , many Mesoamerican the great unwashed viewed mountains and volcanoes as hallowed lieu . For Ichikawa , the significant utilisation of volcanic ash tree is key to his speculation .
“ massive social structure or Pyramid were considered metaphors for sacred mountains , ” he wrote in his email , adding that these places were connected to the origin of macrocosm , deemed living infinite for deities , and a conduit to the sky and Scheol . It ’s possible , he enjoin , that some the great unwashed perceive the eructation as a sign of “ angry Earth , ” and that , by building an important monolithic structure from volcanic ash , they may have slip up upon a solution for sedate this anger .
But as Ichikawa also argues , the large - weighing machine project also facilitate to reestablish societal and political order in the Zapotitán Valley . It would ’ve been a Brobdingnagian residential district attempt ( estimate localize the labor movement force at between 500 and 1,500 the great unwashed ) , requiring cooperation and societal integration , and it likely brought together survivors of the blast and newcomers to the region .
What ’s more , the make - work construction project could ’ve re - established the political power of the swayer in the wake of the disaster . That say , Ichikawa does n’t conceive coercion was involved during the grammatical construction , as a highly hierarchical society did n’t survive at the time . The task may have started as a communal and collaborative effort , but some drawing card may have come out during the cognitive operation of construction , Ichikawa explicate . Interestingly , San Andrés would go on to become the valley ’s principal center .
Ichikawa speculates that former inhabitants of San Andrés came back to rebuild the settlement or that immigrants from an exclusively new culture , perchance from Honduras , re - settled the area . Or possibly a bit of both .
The new newspaper is enthralling , and Ichikawa may be correct about the prompt recovery and how the pyramid was built as a response to the eruption , but more grounds is needed . He admits as much in the paper , saying “ further investigating is required of more sites affect by volcanic events , ” along with next enquiry into the ways in which the survivors procured their food and where the resettlers of San Andrés actually come from . irrespective , the raw research is aid us to empathize how some human lodge bounced back from sudden and calamitous environmental alteration .
