Lasers and radar find typhoon risks in the Philippines
A new way to identify areas at risk for landslides will help countries avoid tragedies like super-typhoon Bopha. The storm slammed into the Philippines in 2012, killing 1,200 people and causing $1 billion in damage. Scientists from the University of the Philippines are using lasers and radar to identify alluvial fans: sediment deposits resulting from streams or debris flows. Debris flows are landslides with rocks and dirt wet enough to …
NASA’s new LVIS sensor to map polar regions with ‘return to sender’ technology
NASA’s Land Vegetation and Ice Sensor has yet to leave the atmosphere, but that’s the long-term plan for this high-flying mapping technology. In the nearer future, LVIS will produce high-resolution, three-dimensional maps of Earth’s unexplored polar regions, allowing scientists to follow changes in ice cover more accurately than ever before. Since 1998, LVIS has mapped rainforest canopies in Costa Rica, surveyed Gulf Coast ocean topography, and even tracked ivory-billed woodpeckers …
