Volcano - Population Exposure Index(GVM)

The work consists of three components: (a) Comprehensive technical information on volcanic hazard, historical events, exposure and vulnerability, (b) Profile of regions and all countries with active volcanoes, (c) Global volcanic ash fall hazard modelling GVM/IAVCEI contributions to GAR15 includes in-depth information on: - Global inventory volcano and their activity rate - Historical events, mortality data, and impacts - Scientific description of volcanic hazards, types of volcanoes, and categories of eruption - Characteristics of vulnerability to volcano hazards, including physical, social, agricultural, etc. - Description of various methodologies for measuring eruption size, classifying hazard level of a volcano, and description of potential impact. - Current status of hazard and risk modelling methods - Current status of monitoring and early warning systems, as well as planning and emergency response practice around the world. The information can be found in the technical background paper titled: “Global Volcanic Hazard and Risk,” (GVM, 2014b). This paper includes 23 case studies from around the world on various topics related to volcanic hazard, risk, and risk management. It also contains Volcano Hazard Index for those volcanoes that can be classified (n=328) and the Population Exposure Index for every volcano worldwide: this in essence provides information on the population exposure within 10, 30 and 100 km of the volcano, weighted by the likelihood of fatalities from volcanic processes. Within the country profiles there is also information on total population within 10, 30 and 100 km and the proportion of that relative to the total country population. The average recurrence intervals for ash falls exceeding 1, 10 or 100 mm, at 10 km resolution.

This dataset was generated using other global datasets; it should not be used for local applications (such as land use planning). The main purpose of GAR 2015 datasets is to broadly identify high risk areas at global level and for identification of areas where more detailed data should be collected. Some areas may be underestimated or overestimated. Given this analysis was conducted using global datasets, the resolution of which is not sufficient for in-situ planning, it should not be used for critical (like life saving) decisions. UNISDR and collaborators should in no case be liable for misuse or misinterpretation of the presented results.
