Geochemical data for: Intense overpressurization at basaltic open-conduit volcanoes as inferred by geochemical signals: The case of the Mt. Etna December 2018 eruption

The reported dataset is annexed to the article “Intense overpressurization at basaltic open-conduit volcanoes as inferred by geochemical signals: the case of the Mt Etna December 2018 eruption”. It consists of five types of parameters: soil CO2 flux from Mt Etna flanks, CO2/SO2 molar ratio of the volcano plume, SO2 and HCl fluxes by volcano plume, and He isotope ratio in some peripheral gas emissions, all of them recorded in the period 2017–2019. The data come from continuous monitoring networks installed on Mt Etna and from discrete samplings carried out at specific sites, all the monitoring facilities being supported by the INGV-Civil Defence joint surveillance program., ,

本数据集附属于论文《基于地球化学信号推断的玄武岩开放通道火山强超压——以2018年12月埃特纳火山喷发事件为例》。该数据集涵盖五类参数：埃特纳火山侧翼土壤CO₂通量、火山羽流的CO₂/SO₂摩尔比、火山羽流的SO₂与HCl通量，以及部分外围气体排放中的氦同位素比值，所有数据的记录时段为2017年至2019年。数据来源于部署在埃特纳火山的连续监测网络，以及在特定点位开展的离散采样，所有监测设施均由INGV与民防部门联合监测计划提供支持。
