Abstract We created a global database of glacierized volcanoes, using a projection optimized for each volcano, to identify locations where land ice (glaciers and ice sheets) and volcanoes co-exist on Earth. Our spatial database melds the Smithsonian Global Volcanism Database (SGVD) and the Randolph Glacier Inventory 6.0 (RGI). We identified all Holocene volcanoes within the SGVD that have glacier ice within radii of 1 km, 2.5 km, and 5 km, and thus have the potential to impact or be impacted by surrounding ice. Our analysis shows that 245 Holocene volcanoes have glacier ice within the specified radii, which are covered partly or fully by 2584 unique glaciers or the Antarctic Ice Sheet. The volcanoes are located in all major volcano-tectonic settings, although the majority (72%) are in subduction zones built on continental crust (greater than 25 km thick). They also cover the majority of the typical compositional ranges for igneous rocks (basalt to rhyolite). Twenty-nine volcanoes, or 12%, have at least 90% ice cover within 5 km, which together comprise 36% of global glacier area on volcanoes. About 20,000 people live within 5 km of a glacierized volcano, while 160 million people live within 100 km of a glacierized volcano and could be impacted by lahars and/or disruption of their water sources during future eruptions. By merging our database with existing ice thickness model estimates we find 850 ± 290 km3 of ice within 5 km of volcanic vents globally. We compare the eruption history, ice volume, and nearby population estimates to identify the most dangerous volcanoes on Earth. The combination of volcano locations and ice thickness estimates allows us to identify 20 (out of 245) glacierized volcanoes that are most likely to experience ‘thick’ ice eruptions, while the vast majority are more likely to experience ‘thin’ ice eruptions.

未来冰川作用的全球地图

摘要 我们创建了一个全球冰川化火山数据库，使用针对每个火山优化的投影来确定地球上陆地冰（冰川和冰盖）和火山共存的位置。我们的空间数据库融合了史密森尼全球火山活动数据库 (SGVD) 和伦道夫冰川清单 6.0 (RGI)。我们确定了 SGVD 内所有具有冰川冰的全新世火山，其半径为 1 公里、2.5 公里和 5 公里，因此有可能影响周围的冰或受到周围冰的影响。我们的分析表明，245 座全新世火山在指定半径内有冰川冰，部分或全部被 2584 条独特的冰川或南极冰盖覆盖。火山位于所有主要的火山构造环境中，尽管大多数（72%）位于大陆地壳上的俯冲带（厚度超过 25 公里）。它们还涵盖了火成岩（玄武岩到流纹岩）的大部分典型成分范围。29 座火山或 12% 的火山在 5 公里范围内至少有 90% 的冰覆盖，这些火山加起来占全球火山冰川面积的 36%。大约有 20,000 人居住在冰川火山 5 公里范围内，而 1.6 亿人居住在冰川火山 100 公里范围内，可能会受到火山泥流的影响和/或在未来火山喷发期间水源中断。通过将我们的数据库与现有的冰厚度模型估计值合并，我们在全球火山喷口 5 公里范围内发现了 850 ± 290 平方公里的冰。我们比较了喷发历史、冰量和附近人口估计值，以确定地球上最危险的火山。
