What is the Pacific Humanitarian Team?
The Pacific Humanitarian Team (PHT) is a network of humanitarian organizations that work together to assist the Pacific Island countries in preparing for and responding to disasters.
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.
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.
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.
The top map shows the average daily rainfall in mm/day for the months of Sep-Nov over the 25 year period: 1979-2003. The map below shows the currently predicted rainfall anomaly for Sep-Nov 2012 (Island Climate Update ICU #144)
The maps opposite show rainfall patterns for Sep-Oct-Nov (southern hemisphere spring) and for Dec-Jan-Feb (southern hemisphere winter) generated from a merged analysis of precipitation from 1979 to 2003.
The top row shows the average daily rainfall that prevails for the given period and ENSO conditions. Darker colors indicate more rain.
The maps show historical storm tracks from 1956-2009 for the months of the southern hemisphere cyclone season (Nov-Apr). Storms that formed during El Niño, La Niña and ENSO Neutral conditions are differentiated to reveal patterns which demonstrate how the El Niño / Southern Oscillation (ENSO) and cyclonic activity are linked.
