  • EarthquakesNapa earthquake may persuade lawmakers to fund earthquake warning system

    Last Sunday’s Napa earthquake may push Congress to increase funding for an earthquake warning system. Building out the West Coast earthquake warning system, called ShakeAlert, would cost $120 million over five years, and an additional $16 million a year to operate. Today, ShakeAlert operates in a testing phase, and sensors notify researchers and volunteer participants when an earthquake has been detected.

  • DisastersSunday tremor may accelerate deployment of West Coast early warning system

    Researchers and individuals working with California’s ShakeAlertsystem received a 10-second warning before last Sunday’s earthquake struck the San FranciscoBay Area at 3.20 a.m. “Earthquake! Earthquake!” the warning system cautioned, followed by “Light shaking expected in three seconds.” Mexico and Japan already have a public earthquake warning system, but a collaboration in California among several institutions to create a similar system is still in an experimental phase. The project needs about $80 million for equipment, software, and other seismic infrastructure upgrades to launch the warning system throughout the West Coast.

  • EarthquakesFirst federal funds for West Coast earthquake warning system

    Efforts by California officials to expand an earthquake warning system for the West Coast gained ground last Tuesday as the House Appropriations Committeerecommended $5 million — the first federal funds specifically for the project — toward the warning system. Analysts project the system will cost $38.3 million to build, and $16.1 million a year to operate and maintain. The $5 million would allow the purchase and installation of additional sensors and hiring of staff.

  • Public alert systemsStates choose different paths to deploying public alert systems

    Thanks to systems such as the Federal Emergency Management Agency’s (FEMA) Integrated Public Alert & Warning System (IPAWS), the technology which allows governments to notify residents quickly of an emergency is becoming increasingly cheaper and more effective. Because of this, states are choosing different and unique paths toward deploying such systems within their infrastructure. States are choosing between giving local governments the lead on alert systems or providing extensive state-wide oversight.

  • DisastersExperts urge deployment of earthquake warning system in California

    Scientists say that California has “99.7 percent chance of experiencing a severe earthquake — magnitude 6.7 or higher on the Richter scale — within the next 30 years.” These scientists are urging Congress to consider funding the full-scale deployment of an early-warning earthquake system on the western coast of the United States following successful testing of a prototype and positive results from similar international systems.

  • Seismic alertInexpensive seismic alert device may help Mexico City residents

    Mexico City has been experiencing an unusually large number of tremors within the past few months, and though the country has one of the most advanced seismic alert systems in the world, many residents are unable to receive notifications before tremors occur. Mexican regulations limit the sale of government-issued earthquake alert receivers to one private company, but since the receivers cost an average of $310, most families are unable to afford them. Andres Meira, a 39-year-old architect, has designed an earthquake alert receiver, which costs only $54 at retail, which taps into the government’s earthquake alert frequency to notify its users of a pending earthquake.

  • Emergency alertsSmall Virginia town debates cost of emergency siren system

    Installing an emergency siren system in Danville, Virginia would be too expensive, Danville fire chief David Eagle said during a recent update to the Danville city council on emergency notification systems. The city’s last siren system was discontinued about twenty-five years ago. A new system would cost between $300,000 and $400,000 to install, and would incur annual maintenance cost.

  • Disaster alertsNew phone alerts for extreme weather events may prevent casualties in India

    India has a mobile phone subscriber base exceeding 929 million people and this is expected to touch 1.15 billion by the end of 2014. An alert system developed for mobiles could reach an estimated 97 percent of the population. Computer science undergraduates have created image-based mobile phone alerts, connected to the Weather Research and Forecasting system.

  • EarthquakesEarthquake early warning? There’s an app for that

    Researchers from the University of California have unveiled a smartphone app designed to provide users an early warning of approaching earthquakes. Based on the proximity of the user to the earthquake’s epicenter, the app will provide alerts of between a few seconds and one minute before a tremor hits.

  • EarthquakesBetter earthquake early-warning system

    Geophysicists have developed a new way of calculating the magnitude of an imminent earthquake by making better use of measurements of the compression waves produced early in the event. They say that the technique could be used to create a better early-warning system for earthquakes that could be used worldwide.

  • Earthquake warningCalif.’s earthquake early warning system bill approved

    California’s earthquake early warning system, State Senate Bill 135, was approved by Governor Jerry Brown. The bill requires the Office of Emergency Services (OES) to develop a comprehensive statewide earthquake early warning system to alert Californians in advance of shaking from an earthquake.

  • Earthquakes warningImproving earthquake early warning systems

    Earthquake early warning systems may provide the public with crucial seconds to prepare for severe shaking. For California, a new study suggests upgrading current technology and relocating some seismic stations would improve the warning time, particularly in areas poorly served by the existing network — south of San Francisco Bay Area to north Los Angeles and north of the San Francisco Bay Area.

  • First respondersHelping first responders identify chemical, biological, and radiological agents

    The U.S. Naval Research Laboratory (NRL) has expanded the reach and capabilities of its rapid urban plume modeling and hazard assessment system, CT-Analyst, by providing a commercial license to Valencia, California-based Safe Environment Engineering (SEE) for the fields of use of public safety, industrial safety and monitoring, and environmental monitoring. CT Analyst is a tool designed to provide first responders with fast and accurate predictions of chemical, biological, and radiological agent airborne transport in urban environments. CT Analyst will be integrated into the existing product line of SEE’s Lifeline MultiMeterViewer software suite.

  • PreparednessArkansas deploys first statewide SmartPrepare system

    Arkansas uses citizen-supplied data for more efficient emergency planning and response. The service allows citizens to create secure profiles online which contain vital details about their household. Public safety officials can use the data to gain greater insight into their communities and identify potential challenges in order to prepare more effectively for disasters, allocate resources, and expedite emergency response and recovery efforts during events.

  • Earthquakes warningsU.S. nation-wide quake early-warning system

    The United States is likely to be struck by a major earthquake within the next twenty years. Scientists say that instead of waiting to experience a devastating earthquake and then invest in preventative measures for subsequent earthquakes, the country should be proactive and take action before the event. Investing in a nationwide earthquake warning system will save lives, prevent destruction of key infrastructure, and reduce the size of the economic loss that may result from an earthquake.
