Significant Global Volcanic Eruptions

Significant Global Volcanic Eruptions This feature layer, utilizing data from the National Oceanic and Atmospheric Administration (NOAA), displays global locations of significant volcanic eruptions. Per NOAA, "A significant eruption is classified as one that meets at least one of the following criteria: Caused fatalities Caused moderate damage (approximately $1 million or more) With a Volcanic Explosivity Index (VEI) of 6 or larger Caused a tsunami Was associated with a major earthquake" Yellowstone eruption (2016) Data downloaded: 02/01/25 Data source: Significant Volcanic Eruptions Data modification: None For more information: Natural Hazards Data Natural Hazards Viewer For feedback, please contact: [e-mail] Thumbnail courtesy of: Esri Basemaps NAIP Imagery Hybrid National Oceanic and Atmospheric Administration Per NOAA, its mission is "to understand and predict changes in climate, weather, ocean, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources."全球重大火山喷发要素图层 本要素图层依托美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的数据制作，展示了全球范围内重大火山喷发的发生点位。根据NOAA的官方定义，"重大火山喷发"需满足以下至少一项判定标准：造成人员死亡；造成中等规模经济损失（约100万美元及以上）；火山爆发指数（Volcanic Explosivity Index, VEI）达到6级及以上；引发海啸；与强震存在关联。 本数据集涵盖2016年黄石火山喷发相关记录，数据下载日期为2025年2月1日，数据来源为《重大火山喷发数据集》，未进行任何修改。 更多信息可查阅：自然灾害数据（Natural Hazards Data）、自然灾害查看器（Natural Hazards Viewer）。 反馈请联系：[e-mail]。 缩略图由Esri基础地图、NAIP影像混合图层提供。 美国国家海洋和大气管理局（NOAA）的官方使命为："探究并预测气候、天气、海洋与海岸带的变化，向公众分享相关知识与信息，并保护和管理海岸与海洋生态系统及资源。"
