Flood is one of the most common geohazards, which also costs most devastation to society. There are areas more vulnerable to floods, where measures are taken to mitigate the impacts, but further research is needed for identifying flood vulnerability in order to make communities in such vulnerable areas more resilient.
Since February, many fires have broken out on the Sumatra peninsula in Indonesia, as UN-SPIDER reported; many of them were deliberately set in order to clean the land. Although this is illegal, it is still a common practice in the region. NASA’s satellites Terra and Aqua monitor these fires from Space.
The risk of deadly hantavirus outbreaks in people can be predicted months ahead of time by using satellite images to monitor surges in vegetation that boost mouse populations, a University of Utah study says. The method also might forecast outbreaks of other rodent-borne illnesses worldwide.
Scientists say they've used satellitedata to measure for the first time the amount of water that rises and falls in the Amazon River floodplain each year. Ohio State University researchers say the information is critical to predicting floods and droughts that might be brought about by global climate change.
According to the new data, the earthquake rupture did not reach the surface which is unusual for an earthquake this size. More importantly, the images confirm that only the western half of the fault segment that last ruptured in 1751 actually ruptured in the current earthquake. “We’re still waiting for the other shoe to drop,” says Tim Dixon, professor of geology and geophysics at the University of Miami Rosenstiel School of Marine & Atmospheric Science.
