Impact of volcanic climate perturbation caused by Laacher See eruption onto the proximal environment and terminal eruptive mechanisms

Laacher See火山喷发非常适合分析火山喷发期间岩石圈（岩浆室-喷口系统）、水圈（地下水、地表水）和大气（通过气候影响和火山喷发引发的强降水）作用力之间高度相关的反馈。Laacher See Tephra现有的粗糙岩石地层细分将被基于事件的地层细分所取代。这个新的框架将允许对喷发历史进行高分辨率的时间评估。对喷发和非喷发事件的更精确定义反过来将导致对控制高度复杂的喷发演变的内部和外部过程的组合进行更实质性的分析。拟议的工作将包括彻底修订和重新解释现有的大量数据库，并辅以实地工作和岩性、岩石学、矿物学和地球化学分析。更好地了解喷发和非喷发机制及其成因，对于评估普林尼火山喷发对环境的多重影响具有重要意义。

The Laacher See eruption is uniquely suited to analyze the highly interrelated feedbacks between lithosphere (magma chamber-vent system), hydrosphere (groundwater, surface water) and atmosphere (via climate impact and eruptiontriggered strong precipitation) forcings during the eruption. The existing rough lithostratigraphic subdivision of Laacher See Tephra will be replaced by an eventbased stratigraphic subdivision. This new framework will allow a high-resolution temporal assessment of the eruptive history. A more precise definition of eruptive and noneruptive events in turn will lead to a more substantial analysis of the combination of internal and external processes that have governed the highly complex evolution of the eruption. The work proposed will include a thorough revision and reinterpretation of the existing voluminous database supplemented by fieldwork and lithological, petrographic, mineralogical and geochemical analyses. A better understanding of eruptive and noneruptive mechanisms and their causes is important in assessing the manifold impacts of a Plinian eruption on the environment.
