We accomplish this by delivering effective forecasts, warnings, and information about volcano hazards based on scientific understanding of volcanic processes. Learn more by exploring USGS volcanic maps.

The IAVCEI CVHR Volcanic Hazard Maps Database is a searchable global collection of volcanic hazard maps. Map classification metadata such as hazard types considered, hazard zone presentation, temporal and spatial scale, zonation methodology, and audience and purpose have been cataloged (see the Diversity of Maps pages) and can be used to search ...

5 天之前 · Long-term hazards assessments identify locations at risk from volcanic hazards. They are released as high-resolution hazards-zonation maps with accompanying explanations, which help guide eruption preparedness plans.

2023年2月8日 · The Volcanic Hazard Maps Database, accessed via the website portal, catalogs the diversity of existing volcanic hazard maps, provides terminology and a classification system for maps, and serves as a community resource for volcanic hazard assessment and mapping.

The USGS has published several volcano-specific hazard maps, which illustrate the potential for ground-based volcanic impacts—lava flows, hot rocks, volcanic gases, and more far-reaching hazards such as ashfall and lahars that flow in valleys that drain the volcano.

2020年9月12日 · The Commission for Hazard and Risk are hosting an online workshop on the 29/30th September 2020 to share and discuss a new web-hosted Volcanic Hazard Map Database with the wider volcano community. This database is searchable through an online interface (available here).

What is a hazard map and why is important? A hazard map is a spatial representation of the footprint of a given volcanic phenomenon. The number of elements and design of the map play a key role on hazard communication. What's the secret code behing hazard map lines?

Here are examples of Mt. Hood and Mt. Adams hazard maps. A lahar hazard map for Mt. Rainer follows.

2023年9月11日 · Volcanic hazard maps are visual, geospatial depictions of the areas that could be impacted by various volcanic phenomena during or subsequent to an eruption. They are developed to communicate a complex array of hazard information to those at risk, or those responsible for managing risk.
