国际研究团队对7300年前日本贵妃火山的灾难性喷发进行了深入调查，发现这场灾难对史前社区的影响远比既往认知复杂。1 由隆德大学领导、剑桥大学教授恩里科·克雷马主持的研究表明，虽然某些地区的人口在喷发后出现下降或消失，但其他地区的人口却依然保持增长。1 这项成果已发表在《科学进展》杂志2026年第12卷第42期。1
研究发现，南九州地区的人口在喷发前已处于下降态势，而北九州地区的人口则在灾难后继续增长。1 对于距离火山较远的地区，人口增长则出现停滞或衰退。1 这些差异表明，绳文社区（狩猎采集者）在面对灾难时展现了多样化的适应能力，通过幸存者迁移、适应性调整和经济创新等方式做出了不同的应对。1
An international research team led by Lund University has revealed that the catastrophic eruption of the Kikai-Akahoya volcano approximately 7,300 years ago produced far more nuanced effects on prehistoric communities than previously understood.1 Rather than uniform devastation across Japan, the volcanic disaster triggered divergent demographic outcomes across different regions, demonstrating the varied adaptive capacities of human societies facing major environmental crises.1
The study, published in Science Advances Volume 12, Issue 42 in October 2026 and led by Cambridge University professor Enrico Crema with senior contributions from Lund University archaeologist Peter Jordan, examined how Jomon hunter-gatherer communities responded to this submarine eruption.1 Researchers discovered that while populations in southern Kyushu had already begun declining before the eruption, northern Kyushu experienced continued population growth in the catastrophe's aftermath.1 Simultaneously, communities in regions more distant from the volcano saw their population expansion stall or reverse.1 These disparate responses reflect how surviving populations adapted through migration, behavioral innovation, and economic restructuring rather than experiencing universal collapse.1
