Disasters

  • Worries about safety of California bridges with eyebar design

    Every so often the Bay Bridge closes because of widening eyebar crack; when the bridge opened seventy years ago, the design was considered safe, but structural engineers now say the eyebar design is an inherently unsafe; trouble is, dozens and dozens of California aging bridges use the flawed design

  • Bay Area cities lag in making housing quake-safe

    Many public buildings in Bay Area cities have been retrofitted to make them more earthquake-resistant; most of the two types of private homes which are especially vulnerable to damage by tremors — wood-frame, “soft-story” buildings and concrete-frame structures that lack sufficient steel reinforcement — have not yet been retrofitted

  • Interference-free radio from Cambridge Consultants

    Cambridge Consultants shows a novel “spectral sensing” cognitive radio technology that will allow any radio product to transmit without interference over the so-called “whitespace” frequencies recently vacated by the U.S. digital TV switchover

  • New Army Corps of Engineers' policy instructs project designers to take rising sea levels into account

    The Army Corps will from now on incorporate estimates of rising sea levels in all its plans for flood control, navigation, and other water projects; the corps has had a planning policy for rising sea levels since 1986, but the instructions were less than a page long, buried in a 1,000-page document and largely ignored; the new policy is articulated in a 44-page stand-alone document

  • U.K. agency to increase flood protection

    The number of properties in England and Wales at significant risk of flooding could increase from 570,000 in 2009 to over 900,000 by 2035 at current levels of flood-defense investment; the Environment Agency says it is planning for the long haul, saying it is already planning to manage a predicted 1 meter rise in sea levels, and a predicted 10 percent increase in wave heights and wind speeds, both of which will increase the threat from coastal surges

  • Army Corps of Engineers in a $1 billion project to protect New Orleans' flank

    The West Bank area of New Orleans is primed for growth, but experts warn that developers and residents should be aware of a problem: the bowl-shaped area is considered by experts as perhaps the city’s most vulnerable flank;’

  • New York receives $3 million boost for cyber security

    The funding will help New York State’s Office of Cyber Security and Critical Infrastructure Coordination (CSCIC) conduct work with the Multi-State Information Sharing and Analysis Center (MS-ISAC); the MS-ISAC is the first and only facility dedicated to state, local and territorial governments in the country and the funding is expected to enhance the center’s capabilities

  • U.S. Congress holds hearings on geoengineering

    Geoengineering — the effort to design systems which would change the world’s climate — was once a fringe phenomenon; it has been moving into the mainstream, though, as more and more scientists are growing increasingly concerned that, even if we commit to cutting emissions drastically, we have already waited too long, and that by the time we actually reduce emissions, enough greenhouse gases will have accumulated to cause serious climate disasters

  • Using technology to prepare vulnerable communities for earthquakes

    Satellite photographs and remotely measured surface heights from NASA will be used for assessing the vulnerability of natural slopes to earthquake-induced landslides; a team of U.K. scientists will also build up a database of slopes that failed in earthquakes; the information collected will include local geology, vegetation, slope angle, distance from the fault, and the amount of ground shaking

  • Israel to use cell phone alert system for rocket attacks

    The IDF says that, in two years, Israeli citizens will receive cell-phone alerts in case of a rocket attack by Iran, Hamas, or Hezbollah; sophisticated rocket sensor will calculate the trajectory of the rockets, predict the impact zone, and send a warning to all phones in that area

  • JASON says computer models cannot predict terrorist events

    Pentagon advisory panel concludes that extreme terrorist events such as the 9/11 attacks cannot be predicted by computer models because the data re too sparse; “it is simply not possible to validate (evaluate) predictive models of rare events that have not occurred, and unvalidated models cannot be relied upon”

  • African desert rift confirmed as new ocean is forming

    Geologists show that seafloor dynamics are at work in splitting African continent; scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea

  • IBM opens new business continuity facility in Izmir, Turkey

    IBM has opened a new Business Continuity and Resiliency Services (BCRS) Center in Izmir, Turkey, replacing the former facility, which has been in operation since 1995; Big Blue operates more than 150 business resilience centers worldwide

  • DHS in trials of next generation multiband radio

    Emergency communication interoperability is getting closer as the day of the single-band radio is coming to an end; DHS’ S&T is testing a multiband radio for emergency services

  • H1N1-induced work-from-home may clog Internet

    Telecommuting is a good idea — up to a point; if, as a result of a pandemic, too many people decide to work from home, this could threaten to overwhelm the Internet, rendering it useless as a way for communicating and conducting transactions vital to public safety and the economy
