China quake forces rethink over hazard maps
Following the Sichuan earthquake, in which more than 65,000 people died, researchers say that similar regions may also be in danger and that seismic hazard maps should be redrawn

Modified helicopters help in search and rescue missions
Researchers in Hong Kong develop a helicopter installed with a video camera and linked to the Global Positioning System (GPS), and which flies on its own on a preset course; helicopter used to survey the Sichuan earthquake area; researchers in U.K. work on a similar concept — but one which envisions using a swarm of self-coordinating helicopters

New analysis of earthquake zone raises questions
Oregon State University researchers offer a new analysis of an earthquake fault line that extends some 200 miles off the southern and central Oregon coast that they say is more active than the San Andreas Fault in California

Aussie student has answer to save Earth from asteroid attack
The bomb dropped on Hiroshima had an explosive yield of 12.5 kiloton; asteroid Apophis, which is now hurtling toward Earth and which will come uncomfortably close to our planet in 2029, packs a punch of 1,375,000 kilotons; competitions are being held to find the best way to stop it in its tracks

Earthquakes endanger New York more than previously believed
A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed; among other things, they say that the controversial Indian Point nuclear power plants, 24 miles north of the city, sit astride the previously unidentified intersection of two active seismic zones

Global warming will reduce frequency but increase intensity of hurricanes
Two variables — ocean temperature and wind shear — are considered to be the two most important factors in predicting hurricane activity, both in operational forecasting and in consideration of climate change; new research shows that global warming will likely reduce the frequency of hurricanes, but increase their intensity

The pandemic potential of H9N2 avian influenza viruses
Researchers show that some currently circulating avian H9N2 viruses can transmit to naïve ferrets placed in direct contact with infected ferrets — but aerosol transmission was not observed, a key factor in potentially pandemic strains

New bird flu strain detected in Nigeria
Nigeria has reported two new highly pathogenic avian influenza outbreaks; laboratory results show that the newly discovered virus strain (H5N1, clade 2, EMA3) is genetically different from the strains that circulated in Nigeria during earlier outbreaks

Five ways for humans to trigger a natural disaster
Most scientists now agree that human activity contributes to a long-term changes in global climate, with serious consequences for humans, animals, and plants; human activity, though, can also trigger sudden “natural” catastrophes

Floods strip Midwest of tons of valuable topsoil
Floods are stripping the Midwest of its most valuable resource: soil; farmers and environmentalists are at odds over what to do with erosion-prone land — take their chances planting crops on marginal land in hopes of good yields and high grain prices, or plant trees, native grasses, or ground cover that act as a natural flood buffer
