The IAVCEI Commission on Volcanic Hazards and Risk (CVHR) Volcanic Hazard Maps Database includes 2020 maps at 612 volcanoes in 54 countries and in 15 languages (as of 2023-12-22).

Overview

The purpose of this website is to serve as a resource for the volcanology community, in particular those engaged with hazard mapping, to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. It also provides guidelines and considerations for volcanic map makers, via a Sourcebook for the Development of Volcanic Hazard Maps. The Volcanic Hazard Maps Database and website were developed by the Working Group on Hazard Mapping, part of the IAVCEI Commission on Volcanic Hazards and Risk (CVHR).

The database and website have some important limitations:

  • Hazard maps found on this website should not be used for emergency purposes. For the most recent, official, operational hazard map for a particular volcano, please seek out the proper institutional authorities on the matter.
  • Inclusion in the database is not a guarantee of map quality. Maps from a wide variety of sources are included, such as official maps from observatories and research result maps from academic literature. Old and outdated maps are included to show the evolution of map design and development through time.
  • Inclusion in the database does not constitute an endorsement by IAVCEI of the map design or content.
  • Exclusion from the database does not indicate any value judgements about the map, rather oversight on our part. Please contact us to suggest additions.
  • The database was populated by examining each map in detail and recording map metadata. Some map metadata was not always readily apparent. As such, there may be errors in some map metadata fields. Please contact us to suggest corrections.

Volcanic Hazard Maps Database

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 for particular maps of interest.
