• Man-induced quakes to help in building safer, sturdier buildings

    A team led by Johns Hopkins structural engineers is shaking up a building in the name of science and safety. Using massive moving platforms and an array of sensors and cameras, the researchers are trying to find out how well a two-story building made of cold-formed steel can stand up to a lab-generated Southern California quake.

  • Ten-fold increase in frequency of Katrina-magnitude storms this century

    Tropical cyclones arise over warm ocean surfaces with strong evaporation and warming of the air. Since 1923, there has been a Katrina magnitude storm surge every twenty years. Researchers found that 0.4 degrees Celcius warming of the climate corresponds to a doubling of the frequency of extreme storm surges like the one following Hurricane Katrina. If the temperature rises an additional degree, the frequency will increase by 3-4 times, and if the global climate becomes two degrees warmer, there will be about ten times as many extreme storm surges.

  • Senate panel signs off on cybersecurity bill

    The Senate Commerce Committee has approved a cybersecurity bill aiming to bolster protection of U.S. critical infrastructure. The full Senate will vote on the bill by the end of the year. The bill codifies parts of of President Obama’s February 2013 cybersecurity executive order. Among other things, the executive order instructs the National Institute of Standard and Technology (NIST) to draft a set of cybersecurity practices and standards.

  • Quake Summit 2013: showcasing research on earthquakes, tsunamis

    Members of a national earthquake simulation research network next week will gather at the University of Nevada, Reno (UNR), for Quake Summit 2013, a scientific meeting highlighting research on mitigating the impact of devastating earthquakes and tsunamis. Titled “Earthquake & Multi-Hazards Resilience: Progress and Challenges,” the annual summit of the 14-site George E. Brown Network for Earthquake Engineering Simulation (NEES), will run from 6 August through 8 August at UNR’s Joseph Crowley Student Center.

  • Online tools accelerate progress in earthquake engineering, science

    A new study has found that on-line tools, access to experimental data, and other services provided through “cyberinfrastructure” are helping to accelerate progress in earthquake engineering and science. The cyberinfrastructure includes a centrally maintained, Web-based science gateway called NEEShub, which houses experimental results and makes them available for reuse by researchers, practitioners, and educational communities. NEEShub contains more than 1.6 million project files stored in more than 398,000 project directories and has been shown to have at least 65,000 users over the past year.

  • Simulations help in studying earthquake dampers for structures

    See video

    Researchers have demonstrated the reliability and efficiency of “real-time hybrid simulation” for testing a type of powerful damping system that might be installed in buildings and bridges to reduce structural damage and injuries during earthquakes. The magnetorheological-fluid dampers are shock-absorbing devices containing a liquid that becomes far more viscous when a magnetic field is applied.

  • Cost of Arctic methane release could be “size of global economy”: experts

    As the Arctic warms and sea ice melts at an unprecedented rate, hitting a record low last summer, the thawing of offshore “permafrost” in the region is releasing methane, a powerful greenhouse gas. Economic modeling shows that the possible methane emissions caused by shrinking sea ice from just one area of the Arctic, the East Siberian Sea, could come with a global price tag of $60 trillion — the size of the world economy in 2012.

  • U.K. winter flooding to get more severe, frequent

    Winter flooding in the United Kingdom is set to get more severe and more frequent under the influence of climate change as a result of a change in the characteristics of atmospheric rivers (ARs). ARs are narrow regions of intense moisture flows in the lower troposphere of the atmosphere that deliver sustained and heavy rainfall to mid-latitude regions such as the United Kingdom.

  • Black Hat event highlights vulnerability of U.S. critical infrastructure

    Cybersecurity researchers at the Black Hat conference now going on in Las Vegas, will demonstrate how hackers can gain access to U.S. critical infrastructure, and even cause explosions in oil and gas facilities, by altering the readings on wireless sensors used by the oil and gas industry. The faulty sensors typically cost between $1,000 and $2,000 each, and hundreds or even thousands of them are used at a single oil, gas, or water facility.

  • NIST seeking comments on energy industry security scenarios

    The National Cybersecurity Center of Excellence (NCCoE) works with industry, academic, and government experts to create open, standards-based, modular, end-to-end solutions to cybersecurity challenges that are broadly applicable across a sector. The solutions are customizable to the needs of individual businesses, and help them more easily comply with relevant standards and regulations. The work is organized around use cases that describe sector-specific challenges.

  • Feds give upstate New York counties $5 million money to repair roads, bridges

    The Federal Highway Administration (FHA) has approved $5 million in emergency funding to help fifteen upstate New York counties make repairs to their roads and bridges damaged in a flood late last month.

  • Warming to reduce snow water storage 56 percent in Oregon watershed

    A new report projects that by the middle of this century there will be an average 56 percent drop in the amount of water stored in peak snowpack in the McKenzie River watershed of the Oregon Cascade Range — and that similar impacts may be found on low-elevation maritime snow packs around the world. The snowpack reduction may have significant impacts on ecosystems, agriculture, hydropower, industry, municipalities, and recreation, especially in summer when water demands peak.

  • Changes to levee system would reduce storm surge risks to New Orleans: study

    Historically, the design of Southeast Louisiana’s hurricane flood risk reduction system has hinged on raising and adding levees in response to river or hurricane events that impact the region. A new study shows that the lowering of man-made levees along 55-kilometer section of the west bank of the Lower Plaquemines river to their natural state, to allow storm surge to partially pass across the Mississippi River, will decrease storm surge upriver toward New Orleans.

  • Lawmakers, citing shortcomings, threaten funding for chemical plant safety program

    Heads of three congressional panels urge DHS secretary Janet Napolitano to take to correct shortcomings in the Chemical Facilities Anti-Terrorism Standards (CFATS) program. “As the authorizers and appropriators of this program, we write to you to express serious reservations about continuing to extend CFATS funding without evidence of substantial programmatic improvement,” the three chairmen write in their letter to Napolitano. The lawmakers pointed to flaws in the program’s risk evaluation system, compliance hurdles, implementation delays, and the failure of the program to identify vulnerable facilities.

  • Motivating businesses to adopt building resiliency standards

    Increased resilience for buildings in the face of hurricanes, earthquakes, terrorism, or cyberattacks has been a major national security focus over the past decade. Such resilient buildings not only would be less susceptible to damage and work interruption but could become community gathering places in a general crisis. It will not be easy, however, to secure voluntary adoption of resiliency standards by industry and builders without adequate justification.
