We synthesize environmental and cultural change following a volcanic eruption at A.D. 846–848 in Subarctic North America to demonstrate how social relationships shaped responses to natural disasters. Ethnohistoric accounts and archaeometric studies reveal differences in human adaptations in the Yukon and Mackenzie river basins that relate to exertions of power over contested resources versus affordances of security to intercept dispersed migrating animals. The ways that pre-contact hunter-gatherers maintained or redressed ecological imbalances influenced respective trajectories of resilience to a major event. Adaptive responses to a volcanic eruption affected the movement of bow and arrow technology and the proliferation of copper use in northwest North America.

我们在北亚北极的公元846–848年火山爆发后综合了环境和文化变化，以证明社会关系如何塑造对自然灾害的反应。民族史记载和考古学研究表明，育空地区和麦肯齐河流域的人类适应差异与争用资源上的权力施加与拦截分散的迁徙动物的安全能力有关。接触前的狩猎者和采集者维持或纠正生态失衡的方式影响了应对重大事件的能力。对火山喷发的适应性反应影响了弓箭技术的发展以及北美西北部铜的使用激增。
