Sheriff Marin County In Partnership With Our Communities


disaster comunication

California's residents deserve reliable public safety services. The federal, state, and local agencies providing these services require efficient wireless voice and data communications systems to receive the public's requests for service, to coordinate the delivery of those services, and to communicate life-safety information among responders. A sufficiently robust and secure public safety radio communications voice and data infrastructure supporting federal, state, and local agency communications is critical to California's future security, health, welfare and vibrancy. California's size, topography, and diverse land use create unique challenges in designing and providing public safety communications systems to meet the needs of the state's population in a cost-effective manner.

Marin Emergency Radio Authority (MERA) - This system unifies public safety response, making it possible for members to more effectively and efficiently communicate with each other and within individual departments.

AlertMarin – The Marin County Office of Emergency Services is urging local residents to register their cell phones or Voice over Internet Protocol (VoIP) devices to receive emergency alerts sent by phone call, text or email on the County’s upgraded notification service. Such alerts could save the lives of you and your family – and registration only takes about one minute on

The upgraded system provides these benefits:

  • The ability to have up to five locations per contact (such as addresses for home, school, work, children’s schools, elderly parents’ homes, etc.)
  • Mobile applications to manage contact information and receive notifications
  • An easy-to-use portal that works with all web browsers

Remember: It’s free! Please sign up to receive emergency alerts at

State of California - Emergency Digital Information Service (EDIS) - The Emergency Digital Information Service (EDIS) delivers official information about emergencies and disasters to the public and the news media in California.

State of California - Emergency Alert System (EAS) - created to enable Federal authorities to warn the American public of a national emergency via the nation's broadcast stations and other communications resources. It was subsequently expanded to enable the National Weather Service and local authorities to warn the public of any threat to the public health, safety, and welfare. The EAS was never used for an actual National emergency but it has been used thousands of times to warn of local, natural, or manmade threats.
