Explore the National Risk Index dataset with the interactive map and data exploration tools. Discover your community's natural hazard risk, compare it to other communities, and create reports.
2 days ago · If there is no map showing in the municipal level, try selecting only up to provincial or regional level. If there is no hazard map available in your selected province, it's either there is no hazard specific to the area or mapping is still ongoing.
Total preliminary hazard maps produced for 2007 was 59, or 125% of the targeted 47 maps, including the latest available for Bohol, Zambales & Aurora, in addition to those earlier produced for Surigao del Norte & Surigao del Sur, Leyte & Southern Leyte. Over-all, these represent 4% of total target PHMs by end of project. One hundred thirty
a collection of user-defined maps that show the people, places, and natural resources exposed to coastal flooding. The maps can be saved, downloaded, or shared to communicate flood exposure and potential impacts. In addition, the tool provides guidance for using these maps to engage community members and stakeholders. The

A variety of hazard processes or phenomena are depicted on volcanic hazard maps (Fig. 5). The specific hazard processes displayed on any map depend upon the nature of the particular volcano, the temporal and spatial scale the map covers, and on the map purpose and audience. Maps may focus on a single hazard process (e.g., lahars) or hazard process ...
Hazard maps can be classified according to whether they are hazard level-focused, with different hazard processes integrated into combined hazard level zones (Fig. 6a-b) or whether they are hazard process-focused, and thus separated into hazardous phenomena-specific zones or groups (Fig. 6c-f). Hazard level-focused maps (Fig. 6a)combine all or most...
Hazard maps can be classified into two main categories based on the timescale the map intends to cover: background or crisis hazard maps. Background, or long-term, hazard maps are usually created in advance of volcanic unrest. They are intended to show the possible distribution of volcanic hazards over long (years to decades) time frames and to be ...
Hazard maps can be classified according to the spatial scale of the map (Fig. 8). Most commonly (71% of unique maps), hazard maps depict the volcano edifice and the surrounding area (Fig. 8a). For some maps (13%), this may include an entire island (Fig. 8b) and can, therefore, involve special considerations, such as the inclusion of maritime hazard...
Hazard maps can also be classified according to their primary intended purpose, though it can often be difficult to ascertain the map purpose unless explicitly stated or unless certain obvious design choices were made. As such, most maps with unknown purpose were designated as multi-purpose. Indeed, many of the maps in the database (47%) were deeme...
Maps can also be classified according to the methodology used to delineate hazard zones (Fig. 9). Hazard zonation commonly incorporates multiple methods or uses different methods for different hazards. The most common zonation methodology (44% of maps, Fig. 10) is based solely on geologic history (Fig. 9a). Geologic history information includes his...
In addition to the hazard zonation methodology, hazard maps differ based on which scenarios were considered for hazard zonation, such as ‘worst-case’ scenarios, scenarios based on eruption sizes, or scenarios that consider certain seasons. Many maps may use a combination of different scenario types or may use different scenarios for different zones...
Hazard maps define hazard zones and their probabilities in different ways, often using a combination of definition types for different hazards and giving multiple hazard zone or probability definitions on a single map. Hazard zone probabilities are commonly defined using qualitative or relative probability (47% of unique maps). These are often cate...
Volcanic hazard maps that show the same hazard processes, use the same methodology, and serve the same purpose may still be very distinct visually due to the wide range of map design choices and cartographic elements that are included or omitted. Map design plays a huge role in the success of information transfer to map users (Thompson et al. 2015;...
Jul 31, 2015 · Through the Philippine Geoportal-DRRM Map web application, the agency integrates data from various government agencies and projects into public online interactive maps pertaining to the various hazards that threaten different parts of the country (see http://www.geoportal.gov.ph/apps/drrm/).
