Emergency Alerting: Capabilities Have Improved, But Additional Guidance and Testing Are Needed.

摘要

An effective system to alert the public during emergencies can help reduce property damage and save lives. In 2004, FEMA initiated IPAWS with the goal of integrating the nation's EAS and other public-alerting systems into a comprehensive alerting system. In 2009, GAO reported on long-standing weaknesses with EAS and FEMA's limited progress in implementing IPAWS. Subsequently, FEMA and FCC conducted the first-ever nationwide EAS test in November 2011. GAO was asked to review recent efforts to implement IPAWS and improve EAS. GAO examined: (1) how IPAWS capabilities have changed since 2009 and what barriers, if any, affect its implementation and (2) results of the nationwide EAS test and federal efforts to address identified weaknesses. GAO reviewed FEMA, FCC, and other documentation, and interviewed industry stakeholders and alerting authorities from six locations that were selected because they have public-alerting systems in addition to EAS and experienced problems during the nationwide EAS test.
