Epidemiological protocols & HIA assessment
Epidemiological protocols for assessment of health impacts in eruption crises
Below are two standardized epidemiological protocols for use during eruption crises. The intent is for these protocols to be applicable in all volcanic contexts and settings, regardless of resource availability, health records systems, or timeframe. Advising relatively simple and inexpensive methods, these protocols mark the necessary first steps in tracking early health signals from inhalation of volcanic emissions. Consistent use among different eruptions will generate a strong, and comparable evidence base of the health impacts of eruptions.
- Basic protocol: for rapid assessment of the respiratory (and other) health impacts from exposure to volcanic emissions.
- Cross-sectional protocol: for detailed assessment of the extent to which exposure to volcanic emissions causes adverse respiratory and other health effects.
The protocols are accompanied by an introductory document which must be read in association with the protocols.
Health Impact Assessment review
We will soon post a critical appraisal of the potential to conduct health impact assessments for volcanic environments and whether extrapolation of concentration-response functions from outdoor air pollution HIA studies may be used for assessing the extent of volcanic health risks to communities.
Ash Collection and analysis protocols
IVHHN has produced a set of protocols for scientists to enable rapid collection and analysis of ash.
Some protocols are provided fully translated into Japanese and Spanish. You can still use the translation tool on the right hand side to automatically translate the English articles into any of the available languages.

Volcanic Ash Leachate Analysis Database
Provides information on adsorption of species onto ash and sampling and applications of ash leachates as well as the leachates database.
Protocol for analysis of bulk ash samples
Ash Collection Procedures
Procedures for the collection of ash in various situations and purposes.
Ash Grain-Size Distribution Analysis
Grain-size distribution (GSD) analysis is a vital step in the assessment of the health hazard of volcanic ash, giving the quantity of respirable (< 4 µm) and sub-10µm particles in a bulk sample. This section details how to carry out GSD on ash samples.
