Congress to establish a commission to study threat of asteroid impact on Earth
The annual probability of the Earth being struck by a huge asteroid or comet is small, but the consequences of such a collision are so calamitous that it is prudent to appraise the nature of the threat and prepare to deal with it, experts say; Congress agrees

New technology could lead to an earthquake prediction system
A new airborne radar-based mapping technology allows scientists to see earthquake images on the ground for the first time; the airborne images show tiny or large motions that occurred beneath the surface of the earth, on the fault line, which can not be seen by flying over an area or walking on the surface

Scientist says nuclear weapons best bet for saving Earth from asteroids
Scientists argue that the best way to prevent a large asteroid from doing grave damage to Earth is to blast the asteroid with nuclear weapons; the sheer power of a nuclear explosion may make it the most practical and cost-effective option for deflecting or fragmenting asteroids, compared with alternatives such as chemical fuel or laser beams; for one thing, a nuclear explosive would be cheaper to launch into space due to its large amount of energy per unit mass; in contrast, a non-nuclear blast might require several launches for an equivalent amount of power

Italian scientists face manslaughter charges for failing to predict 2009 L'Aquila earthquake
Italian prosecutors have issued indictment against six scientists for failing to warn the residents of L’Aquila about the 6 April 2009 earthquake; the magnitude-6.3 earthquake caused 308 deaths and 1,600 injuries, and left more than 65,000 people homeless; prosecutors say the scientists participated in a press conference on 31 March, in which they encouraged residents not to move out of the L’Aquila region; coming to the defense of the seismologists, nearly 4,000 scientists from around the world have signed a letter to Italy’s president, urging him to focus on earthquake preparation rather than holding scientists responsible for something that they cannot do — predict earthquakes

2010 hurricane season is going to be a busy one
The 2010 hurricane season, which began 1 June, is going to be a busy one: the National Hurricane Center forecasts a 70 percent chance of eight to fourteen storms reaching hurricane strength, and three to seven becoming dangerous “major” hurricanes of category 3 and above

Attention to design details will make buildings withstand hurricanes
One example of design ideas architects in hurricane-prone regions should follow: design buildings with square, hexagonal, or even octagonal floor plans with roofs of multiple slopes such as a four-sloped hip roof; these roofs perform better under wind forces than the gable roofs with two slopes; gable roofs are common only because they are cheaper to build; research and testing demonstrate that a 30-degree roof slope will have the best results

Scientists monitor earthquakes in real time
Better to understand earthquakes like El Mayor-Cucapah, researchers have set up GPS instruments throughout the state of California, as part of the California Real Time Network (CRTN); the CRTN consists of more than 130 continuous GPS receivers run by numerous agencies

2010 hurricane season unusually active
As if the on-going oil spill were not enough, people who live near the Gulf of Mexico and the Atlantic should brace themselves for an unusually active hurricane season this year (the hurricane seasons lasts from 1 June to 30 November); FSU researchers say there will be an average of seventeen named storms with ten of those storms developing into hurricanes in the Atlantic this season; the historical seasonal average is eleven tropical storms with six of them becoming hurricanes

Oregon town plans first tsunami-resistant building on stilts
Geological findings in recent years suggest there is a one-in-three chance that in the next half century a mega-earthquake will tear the seafloor apart off the Oregon Coast; huge waves would surge onto coastal communities in as little as fifteen minutes; an Oregon city plans tsunami-resistant buildings on stilts

Berkeley quake demonstration shows bridge safety ideas
Researchers demonstrate new bridge design that can withstand powerful earthquakes; the design concept relies on building segmented bridges with seismic isolators between the segments; the design would be particularly useful for long stretches of elevated freeways and high-speed rail lines that often run on elevated tracks

The long view
Protecting the U.S. power grid
The U.S. power grid is made up of complex and expensive system components, which are owned by utilities ranging from small municipalities to large national corporations spanning multiple states. A National Academy of Sciences report estimates that a worst-case geomagnetic storm could have an economic impact of $1 trillion to $2 trillion in the first year, which is twenty times the damage caused by a Katrina-class hurricane.
More than 143 million Americans at risk from earthquakes
More than 143 million Americans living in the forty-eight contiguous states are exposed to potentially damaging ground shaking from earthquakes, with as many as twenty-eight million people in the highest hazard zones likely to experience strong shaking during their lifetime, according to new research. The research puts the average long-term value of building losses from earthquakes at $4.5 billion per year, with roughly 80 percent of losses attributed to California, Oregon, and Washington. By comparison, FEMA estimated in 1994 that seventy-five million Americans in thirty-nine states were at risk from earthquakes. In the highest hazard zones, the researchers identified more than 6,000 fire stations, more than 800 hospitals, and nearly 20,000 public and private schools that may be exposed to strong ground motion from earthquakes.
A large Ventura Fault quake could trigger a tsunami
Earthquake experts had not foreseen the 2011 magnitude-9 Japan earthquake occurring where it did, so soon after the disaster, scientists in Southern California began asking themselves, “What are the big things we’re missing?” For decades, seismic experts believed the Ventura fault posed only a minor to moderate threat, but new research suggests that a magnitude-8 earthquake could occur on the fault roughly every 400 to 2,400 years. The newly discovered risk may even be more damaging than a large earthquake occurring on the San Andreas Fault, which has long been considered the state’s most dangerous. Unlike the Ventura fault, the San Andreas Fault is so far inland in Southern California, that it does not pose a tsunami risk. A large earthquake on the Ventura fault, however, could create a tsunami that would begin “in the Santa Barbara Channel area, and would affect the coastline … of Santa Barbara, Carpinteria, down through the Santa Monica area and further south.”
Coastal communities can lower flood insurance rates by addressing sea-level rise
City leaders and property developers in Tampa Bay are urging coastal communities to prepare today for sea-level rise and future floods in order to keep flood insurance rates low in the future. FEMA, which administers the National Flood Insurance Program(NFIP), is increasing flood insurance premiums across the country, partly to offset losses from recent disasters such as hurricanes Katrina and Sandy. Cities can reduce insurance premiums for nearly all residents who carry flood coverage by improving storm-water drainage, updating building codes to reflect projected rise in sea-levels, moving homes out of potentially hazardous areas, and effectively informing residents about storm danger and evacuation routes.
California drought highlights the state’s economic divide
As much of Southern California enters into the spring and warmer temperatures, the effects of California’s historic drought begin to manifest themselves in the daily lives of residents, highlighting the economic inequality in the ways people cope. Following Governor Jerry Brown’s (D) unprecedented water rationing regulations,wealthier Californians weigh on which day of the week no longer to water their grass, while those less fortunate are now choosing which days they skip a bath.
