Volcanic Hazard, Historical, Baseline, Global (v1.0)


Volcanoes represent geological formations where magma surfaces during volcanic activities. These natural phenomena are known for their potential to significantly impact both people and property, as well as causing further-ranging issues in air transportation, power generation and delivery, and flooding and mudslides. This dataset categorizes locations around the world into 5 risk categories based on their proximity to volcanic hazards such as lava, pyroclastic flows and lahars. Note that the hazard from ash and volcanic gasses is not captured in this dataset.

Technical Description

The Volcanic Hazard Historical Risk product captures the baseline historical risk of volcanic activity, proximal to volcanic hazards (e.g., pyroclastic flows, lahars, lava). Volcanic Hazard Level is derived from the Smithsonian Institution Global Volcanism Program (GVP) volcano dataset, GVP eruption dataset, and the British Geological Survey LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database. These data provide volcano location, maximum volcanic explosive intensity (VEI), and dates of previous eruption. This dataset does not include data for hazard from volcanic ash.

This dataset contains the following fields:

  • volcanic_hazard_index: The volcanic hazard index classifies locations based on their historical risk from volcanic activity. Values are integers ranging from 0-4 reflecting the lowest to highest volcanic hazard levels, with 0 being No Risk, 1 being Very Low Risk, 2 being Low Risk, 3 being Moderate Risk, and 4 being High Risk.
