公元6世纪，北半球出现了相当长的一段时间的降温，扰乱了全球大部分地区的人类社会，这被归因于火山对气候的强迫。公元540年的一次热带大喷发被认为起到了关键作用，但到目前为止，关于源火山还没有达成共识。在这里，我们提出了证据，证明墨西哥南部的El Chichon是最有可能的候选火山，这是基于对火山喷发历史的精炼重建。一个新的年代学框架，来自墨西哥湾远端的特弗拉沉积和世界上最大的全新世海滩脊平原，使我们能够肯定地将一次重大爆炸事件与两极冰芯记录中显著的火山硫尖峰联系起来，日期为公元540年。我们推测，火山喷发产生的巨大的火山灰坠落对玛雅社会产生了严重的环境影响，导致了暂时的文化衰落、遗址遗弃和玛雅文明核心区内的移民。
A remarkably long period of Northern Hemispheric cooling in the 6th century CE, which disrupted human societies across large parts of the globe, has been attributed to volcanic forcing of climate. A major tropical eruption in 540 CE is thought to have played a key role, but there is no consensus about the source volcano to date. Here, we present evidence for El Chichon in southern Mexico as the most likely candidate, based on a refined reconstruction of the volcano’s eruption history. A new chronological framework, derived from distal tephra deposits and the world’s largest Holocene beach ridge plain along the Gulf of Mexico, enabled us to positively link a major explosive event to a prominent volcanic sulfur spike in bipolar ice core records, dated at 540 CE. We speculate that voluminous tephra fall from the eruption had a severe environmental impact on Maya societies, leading to temporary cultural decline, site abandonment, and migration within the core area of Maya civilization.
