Here we list resources that people and agencies can use to prepare for and deal with ash.

Health Hazard Guides

The International Volcanic Health Hazards Network (IVHHN) is an umbrella organisation for all research and information on volcanic health hazards. IVHHN has produced guidelines and databases on volcanic health issues, and information resources intended for the public and emergency managers.

    New Global Ash Impact Posters

    Below is a series of posters, commissioned by USAID, the Volcano Disaster Assistance Program and US Geological Survey, providing concise best practice information for critical infrastructure managers to effectively prepare for, respond to, and recover from ash-producing volcanic eruptions. These posters are being translated into Spanish, Indonesian, French and Tagalog/Filipino and will be posted on this page when available.

    Content is based on the latest international research and informed by observations from around the world. It is modified from a set of New Zealand-focused posters commissioned by the Auckland Lifelines Group.
