Schools are setting safety plans for fall. Most still don’t have earthquake early warning connected.

School districts across California, Oregon, and Washington finalize their safety plans over the summer. Budgets get approved and emergency binders get updated. By August, the plan is the plan for the year.

And most of those plans still treat earthquake early warning as something that happens on people’s phones.

That’s a problem. Cell phone alerts through the Wireless Emergency Alert system work fine if you’re sitting at home. They don’t solve the problem a school actually has: 800 students in 30 classrooms who need a coordinated response before shaking starts, not a buzz in a teacher’s pocket three seconds into it.

The phone alert gap

ShakeAlert, the USGS earthquake early warning system, delivers alerts through multiple channels. The one most people know is the cell phone notification that comes through WEA or apps like MyShake. But cell phone delivery has limitations in a school setting.

Phones are often silenced, stored in lockers, or prohibited during class. Even when a teacher’s phone goes off, the alert reaches one person in the room. There’s no building-wide notification. No automated PA announcement. No coordinated action across the campus.

A study published by USGS researchers in the International Journal of Disaster Risk Reduction surveyed school superintendents across the West Coast and found that awareness of ShakeAlert was low and adoption was almost nonexistent. The biggest barrier? Perceived cost and a lack of clarity on how to actually integrate it.

What integration looks like

Connecting earthquake early warning to a school’s existing systems isn’t as complicated as it sounds. Licensed ShakeAlert technology partners build devices that receive alerts directly from the ShakeAlert system and trigger automated actions. In a school, that typically means:

The PA system announces a warning automatically, campus-wide, before shaking arrives. Staff and students hear a clear tone and message without waiting for someone to pick up a phone, process what’s happening, and press a button.

That’s the core of it. Some districts also connect alerts to other building systems, like door holds or HVAC shutoffs, but the PA integration alone changes the response completely. Instead of one teacher checking their phone while the room starts shaking, every room on campus gets the same warning at the same time.

The Brawley earthquake swarm in May 2026 triggered ShakeAlert multiple times over 48 hours. A school connected to the system would have received automated warnings for each event. A school relying on cell phones would have gotten inconsistent coverage at best.

What to put on the summer checklist

If you’re responsible for a school district’s safety plan, summer is when this gets decided. Here’s what the conversation should include:

Does our campus have building-level earthquake early warning, or are we relying on personal devices? If the answer is personal devices, that’s the gap. Cell alerts are a supplement, not a system.

Can our PA system receive automated alerts? Most modern PA and mass notification systems can integrate with ShakeAlert technology partners. If the system is older, this is worth evaluating before the school year starts.

Have we updated our earthquake plan beyond Drop, Cover, and Hold On? The CalOES guide for nonstructural earthquake hazards in schools covers what falls, breaks, and becomes a hazard in a classroom. That checklist should be part of every summer walk-through.

Do staff know what an earthquake early warning sounds like? If the system sends an alert and no one recognizes the tone, the warning is wasted. Training should happen before the first drill, not during it. We covered this in more detail in our earlier post on what schools should have in place for earthquakes.

The budget conversation

Earthquake early warning hardware for a school campus is not a capital construction project. It’s closer to the cost of a fire alarm panel upgrade. And unlike a retrofit or structural improvement, it can be installed over a summer break without disrupting the school year.

The harder question is usually who owns the decision. Facilities? The safety committee? The superintendent’s office? In districts where no one owns it, nothing happens. If you’re reading this and you’re not sure who would approve this purchase at your district, that’s the first thing to figure out.

California’s seismic network is on track to reach full installation by December 2026, which means ShakeAlert coverage is improving. The sensor infrastructure is getting built. The question for schools is whether they’ll be connected to it.
