• 2002 Alaska earthquake helped set standards for buildings, bridges

    The Denali 7.9 earthquake that hit Alaska in 2002 was the largest to hit the United States in more than 150 years, and the strongest ever recorded in Alaska; no one was killed and only a few people were injured; the only severe damage the earthquake caused was to a few highways, but the damage was not significant enough to close them; the earthquake set new national standards for building bridges as well as giving seismologists a better understanding of how earthquakes affect frozen ground

  • Future warming likely to be on high side of climate projections: analysis

    Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by scientists at the U.S. National Center for Atmospheric Research (NCAR); NCAR says that the findings could provide a breakthrough in the longstanding quest to narrow the range of global warming expected in coming decades and beyond

  • Nor'easter batters NYC, New Jersey

    A nor’easter battered New York and New Jersey on Wednesday with rain and wet snow, plunging homes back into darkness, stopping commuter trains, and inflicting yet more misery on thousands of people still trying to recover from Superstorm Sandy; ordinarily, the nor’easter would not pose major problems, but this was not the case yesterday, as the storm hit an area where electrical systems were still fragile and many of Sandy’s victims still busy cleaning their homes and coping with deepening cold

  • MIT researchers develop method to help communities plan for climate risk

    As the devastation left by Sandy continues to reverberate, decision-makers at every level are asking: How can we be better prepared? MIT researchers developed a tool to assess regional risks of climate change and potential impacts on local infrastructure and planning; the tool helps policymakers, city planners, and others see the possible local effects of climate change, such as long-term temperature and precipitation changes, allowing local planners to evaluate risks, and how these risks could shape crops, roads, and energy infrastructure

  • Dealing with power outages more efficiently

    When there is a power failure, the utility companies, public officials and emergency services must work together quickly; researchers have created a new planning software product that enables all participants to be better prepared for emergency situations

  • The limitations of climate models

    How accurate is the latest generation of climate models? Climate physicists have compared them with old models and draws a differentiated conclusion: while climate modeling has made substantial progress in recent years, we also need to be aware of its limitations

  • Inflatable giant plugs could have saved NYC subway system

    Inflatable plugs being developed with funding from DHS, could have saved some of New York’s subway and highway tunnels from flooding during Hurricane Sandy, according to the developers of the plugs; DHS successfully tested a plug earlier this year, using a 16-foot diameter prototype to hold back pressurized water at a test tunnel in Morgantown, West Virginia; the idea was originally intended to protect tunnels from terrorist attacks

  • Dutch flood-protection may be suitable for New York, other East Coast cities

    Megastorms and disasters are not going to continue to be once in a lifetime storms, but instead become more of an annual occurrence; experts say that the combination of more frequent megastorms and rising sea levels across the east coast would forcemany cities to get serious about flood protection

  • Long-term sea level rise could cost Washington, D.C. billions

    New study projects that the city of Washington, D.C., and federal property in the city, could suffer billions of dollars in damage if sea level rise as a result of global warming increases over the next century. Potential for significant damage will be even greater in the event of extreme weather like Hurricane Sandy

  • 2011 Virginia quake triggered landslides very far away

    The 2011 Mineral, Virginia M-5.8 earthquake was felt over an extraordinarily large area; a new study details landslides triggered by the earthquake at distances four times greater and over an area twenty times larger than previously documented for M-5.8 earthquakes worldwide

  • Many NYC buildings to remain closed for weeks, months for clean-up, repairs

    Water and winds produced by Hurricane Sandy destroyed mechanical and electrical systems in many commercial and residential buildings in Lower Manhattan; as a result, many buildings in the area are weeks or months away from being repaired and fully operational

  • Protecting New York City from storms, surges

    Almost a week after Hurricane Sandy hit New York City; people are still picking up the pieces of their former lives; for New York officials, the next step is decide how best to protect New York City from a similar disaster in the future; there are many ideas and proposals, ranging from moveable sea gates, to expanding protective marshlands and wetlands, to creating a system of artificial reefs in the channel along the Red Hook and Gowanus neighborhoods of Brooklyn, made out of rocks, shells, and fuzzy rope that will promote the growth of oysters

  • USGS sampling water in Hurricane Sandy’s aftermath to ensure public health

    Excessive nutrients in U.S. rivers, streams, and coastal areas are a major issue for water managers, because they cause algal blooms that increase costs to treat drinking water, limit recreational activities, and threaten valuable commercial and recreational fisheries; U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane

  • Obama, Romney differ on major homeland security issues

    Tomorrow, Tuesday 6 November, American voters will choose between Barack Obama and Mitt Romney as the next president of the United States; the state of the U.S. economy and the best ways to reduce unemployment and increase the pace of economic growth were at the center of the campaign, leaving little room for other issues. Homeland security issues, in particular, played little, if any, role in the campaign or in the three debates between the presidential candidates and the debate between the vice-presidential candidates; still, if we examine the policy proposals each candidate has made, and also examine the details of policies posted on his Web sites, the differences between the candidates’ approaches on three major homeland security issues – immigration, cybersecurity, and infrastructure – are considerable

  • States, localities to assume more responsibilities for rebuilding U.S. aging infrastructure

    Infrastructure in the United States is in bad shape; Maryland needs more than $100 million a year for its bridges; Virginia needs $125 million per year for roads that need repaving; Washington’s failure to create a long-term funding plan to repair the nation’s infrastructure is forcing state and local governments to fill the void in federal funding
