earthquake

The ASEAN region is located at the intersection of three major tectonic plates namely Eurasian, Indo-Australian and the Pacific plates, and one minor plate, Philippine plate. This condition generates thousands of earthquake every year most of which are potentially destructive. In recent years, several big earthquakes occurred in some parts of
ASEAN countries which caused considerable damage to
buildings and other structures, landslides in mountainous regions, ground subsidence and ground rupture. These big earthquakes have also caused major fatalities. What makes an earthquake more devastating is the fact that it may generate tsunami with up to 10 meter high waves which add to the extent of the damage, especially in areas along the coast.

To monitor earthquake activities, and to help mitigate the effects of earthquake disasters, most countries in ASEAN have established their National Seismological Centres (NSCs). While NSCs in some countries are quite modern, others are still in the process of upgrading. Ideally each of the upgraded NSC should have a real time monitoring system and other facilities for rapid dissemination of earthquake information. Continue Reading

Killer Wind Funnels

Tornadoes are vertical funnels of rapidly spinning air. Their winds may top 250 miles (400 kilometers) an hour and can clear-cut a pathway a mile (1.6 kilometers) wide and 50 miles (80 kilometers) long.

Twisters are born in thunderstorms and are often accompanied by hail. Giant, persistent thunderstorms called supercells spawn the most destructive tornadoes. Continue Reading

Speeding Snow

While avalanches are sudden, the warning signs are almost always numerous before they let loose. Yet in 90 percent of avalanche incidents, the snow slides are triggered by the victim or someone in the victim’s party. Avalanches kill more than 150 people worldwide each year. Most are snowmobilers, skiers, and snowboarders.

deadly cyclone

NASA satellite data and a new modeling approach could improve weather forecasting and save more lives when future cyclones develop.

About 15 percent of the world’s tropical cyclones occur in the northern Indian Ocean, but because of high population densities along low-lying coastlines, the storms have caused nearly 80 percent of cyclone-related deaths around the world. Incomplete atmospheric data for the Bay of Bengal and Arabian Sea make it difficult for regional forecasters to provide enough warning for mass evacuations.

In the wake of last year’s Cyclone Nargis — one of the most catastrophic cyclones on record — a team of NASA researchers re-examined the storm as a test case for a new data integration and mathematical modeling approach. They compiled satellite data from the days leading up to the May 2 landfall of the storm and successfully “hindcasted” Nargis’ path and landfall in Burma. Continue Reading
