Tectonic Plates and Fault Lines

The region is home to extremes in elevation and the world's most active seismic and volcanic activity. Southwest of India, the Maldives has a maximum height of just 230cm, while far to the north, the Tibetan Plateau averages over 4,500m across its 2.5 million square kilometres and is home to all 14 of the world's peaks above 8,000 metres. The Himalaya were born 70 million years ago when the Arabian Plate collided with the Eurasian plate.

Tropical Storm Risk Zones

This map was derived from the Munich Reinsurance Company's World Map of Natural Hazards and shows tropical storm intensity based on the five wind speeds of the Saffir-Simpson Hurricane Wind Scale.

Sixteen years of wildfires in Asia-Pacific

Wild land fires and other biomass fires annually burn a total land area of between 3.5 and 4.5 million km2, equivalent to the surface area of India and Pakistan together, or more than half of Australia. This makes it one of the most spatially prevalent hazards after drought.

Volcanic Explosivity in Asia-Pacific

This map shows the density of volcanic eruptions based on the explosivity index for each eruption and the time period of the eruption. Eruption information is spread to 100km beyond point source to indicate areas that could be affected by volcanic emissions or ground shaking.

Flood Risk

Risk assessment for an area exposed to multiple hazards requires solutions to compare the risks. This map was generated by adding the value of mortality to the cumulated risk of cyclones, earthquakes, floods and landslides. Categories of risk based on expected annual losses.

This product was designed by UNEP/GRID Europe for the Global Assessment Report on Risk Reduction (GAR). It was modeled using global data.

Earthquake Intensity Risk Zones

This map shows earthquake intensity zones in accordance with the 1956 version of the Modified Mercalli Scale (MM), describing the effects of an earthquake on the surface of the earth and integrating numerous parameters such as ground acceleration, duration of an earthquake, and subsoil effects. It also includes historical earthquake reports.

Physical Exposure to Drought

Drought is a phenomenon that affects more people globally than any other natural hazard. Unlike aridity, which refers to a semi-permanent condition of low precipitation (desert regions), drought results from the accumulated effect of deficient precipitation over a prolonged period of time.

The units used in this product refer to the expected average annual population (2010 as the year of reference) exposed (inhabitants). The dataset includes an estimate of the annual physical exposure to drought. It is based on three sources:

  1. Philippines - Heavy rains hamper humanitarian activities in Bopha-affected areas. The revised Action Plan was launched in Manila on 25 January asking for US$76 million. As of 19 Jan, nearly 6,500 people are displaced in evacuation centers while nearly 845,000 are displaced outside of formal centers.
