The Alerting Authority
The Alerting Authority is a podcast dedicated to improving how we warn the public when seconds matter. Hosted by Jeanette Sutton, a leading researcher in public alerts and warnings, and Eddie Bertola, an expert in emergency communications technology, the show brings together practitioners, policymakers, technologists, and thought leaders shaping the future of public alerting.
Each episode dives deep into real-world challenges behind creating, issuing, and delivering life-saving alerts. From Wireless Emergency Alerts (WEA) and the Emergency Alert System (EAS) to IPAWS implementation, crisis messaging, public behavior, and alerting policy, the hosts explore what works, what fails, and why.
Rather than focusing solely on tools or software, The Alerting Authority examines the “human side” of emergency communication—decision-making under pressure, message design, training gaps, coordination across agencies, and the psychology of how people interpret warnings.
The podcast aims to empower emergency managers, communicators, and public safety professionals with actionable insights, practical guidance, and candid conversations with the people who have shaped, studied, and experienced alerting at every level.
Whether you’re responsible for issuing alerts, designing systems, researching risk communication, or simply interested in how warnings save lives, The Alerting Authority is your go-to source for understanding and improving public alerting in a complex and rapidly evolving world.

Inside the Tsunami Warning System: What Really Happened During the 2024 West Coast Alert—and How Emergency Alerts Must Evolve
In December 2024, millions of people across California, Oregon, and the San Francisco Bay Area received a sudden Wireless Emergency Alert warning of a possible tsunami—an alert that stopped daily life in its tracks and raised urgent questions about how tsunami warnings are issued, who receives them, and what the public is actually expected to do.
In this in-depth episode, Jeannette Sutton and Eddie Bertola sit down with Dave Snider of the National Tsunami Warning Center to unpack exactly what happened during that historic alert—and what it revealed about the strengths, limitations, and future of tsunami warning and public alerting systems in the United States.
Dave walks listeners through the real decision-making process behind tsunami warnings, explaining why these alerts are issued out of an abundance of caution, how earthquake magnitude thresholds are evaluated, and why tsunamis fundamentally differ from weather events that can be predicted days in advance. The conversation explores the critical distinction between tsunami warnings, advisories, and watches, and why terminology that works for hurricanes or tornadoes can create confusion when applied to earthquakes and ocean hazards.
The episode also dives deep into the technology behind public alerts, including IPAWS, Wireless Emergency Alerts (WEA), Emergency Alert System (EAS), Weather Forecast Offices (WFOs), and county-level opt-in alerting systems. Dave explains why entire counties—sometimes stretching far inland—receive tsunami warnings, how overlapping geographic boundaries like forecast zones and FIPS codes contribute to over-alerting, and why alert fatigue is a growing concern for emergency communications.
A major focus of the discussion is partnership: the indispensable role of state, county, and local alerting authorities in providing follow-up messaging, local context, and actionable guidance after the initial federal alert is issued. Listeners will gain a clear understanding of what the National Weather Service can and cannot do, and why coordinated, consistent messaging at every level is essential to public safety.
Looking ahead, Dave shares his vision for the future of tsunami warnings, including improved geo-targeting with smaller polygons, better message consistency across platforms, redesigned tsunami.gov services, and a more complete end-to-end communication lifecycle—from the first alert to cancellation and post-event review.
Whether you’re an emergency manager, public safety communicator, policy maker, or simply someone who received the 2024 alert and wondered “Why did I get this?”, this episode provides rare behind-the-scenes insight into a system we all depend on—often without realizing how complex it truly is.
