Fifty years of tropical storms in Asia-Pacific
This map shows a consilidated history of tropical storm paths over the past 50 years in the Asia-Pacific region. The area of calm either side of the equator can be seen clearly, leaving Indonesia, Malaysia,
Singapore and Papua New Guinea largely unaffected by major storms.
Using an innovative approach with GIS and remote sensing, the Oak Ridge National Laboratory LandScanTM is the community standard for global population distribution. At approximately 1 km resolution LandScan is the finest resolution global population distribution data available and represents an ambient population (average over 24 hours).
Temperatures in the Asia-Pacific region can go very high with central India reaching 50oC or more. The Tibetan plateau rarely exceeds 20oC because of its high elevation.
These temperatures are based on average highs over a period of approximately 50 years. Maximum temperatures in the region may therefore be from different months of the year and a temperature in any given location may exceed these maximums.
Köppen-Geiger Climate Classification
The highly referenced climate classification map of Wladimir Köppen was published for the first time in 1900 and updated in its latest version by Rudolf Geiger in 1961.
Climate classification is applied to a broad range of topics in climate and climate change research as well as in physical geography, hydrology, agriculture, biology and educational aspects.
The Human Footprint
Human influence on the earth’s land surface is a global driver of ecological processes on the planet, en par with climatic trends, geological forces and astronomical variations. The Wildlife Conservation Society (WCS) and the Center for International Earth Science Information Network (CIESIN) at Columbia University joined together to systematically map and measure the human influence on the earth’s land surface today.
This map shows the average amount of precipitation falling in a year, based on approximately 50 years of data. The figures shown do not therefore represent the amount of precipitation that may occur in any given year.
OCHA in the Pacific
The Pacific is one of the most disaster-prone regions in the world. Small, vulnerable island states are isolated by vast expanses of ocean. They experience frequent and intense disasters with disproportionately high economic, social and environmental consequences.
In 1999, OCHA established a Regional Office for the Pacific to mobilize and coordinate effective and principled humanitarian action in partnership with national and international actors
Elevation and Bathymetry
The region is home to the world's highest mountain, Mount Everest (Sagarmatha in Nepal and Chomolungma in China) at 8,848m, as well as the deepest surveyed point in the oceans,
Challenger Deep in the Marianas Trench at 10,911m.
The Asia-Pacific region contains a diverse array of cultures, environments, and societies. One of the fastest growing economic regions in the world, it is also the most disaster-prone. While natural disasters affect the region frequently, as this region continues along its path of development, regional partnerships will be essential in developing the capacities of countries to reduce risk and vulnerability and to respond to disasters.
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.
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:
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.
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.
