Federal layoffs threaten earthquake alerts in WA

As we mark 24 years since the devastating Nisqually earthquake, the Trump administration's layoffs at NOAA could jeopardize crucial earthquake detection systems. Fox 13’s Alejandra Guzman looks into the potential impacts with state seismologist Harold Tobin.

Twenty-four years ago today, Washington state was rocked by the 6.8 magnitude Nisqually earthquake, leaving hundreds injured and causing billions in damage.

As the anniversary arrives, many reflect on the lessons learned and the ongoing need for earthquake preparedness.

A major wake-up call

The backstory:

On February 28, 2001, at 10:54 a.m., the Nisqually earthquake struck deep beneath the Puget Sound region. The quake lasted for approximately 30 seconds, shaking buildings from Olympia to Seattle and beyond. While no direct fatalities were reported, more than 400 people sustained injuries, and economic losses surpassed $2 billion.

Seismologists noted that the quake occurred about 35 miles below the surface, which helped reduce widespread devastation. However, the event served as a stark reminder of the region’s vulnerability to seismic activity.

Changes in infrastructure, preparedness

One of the most significant changes following the Nisqually quake was the demolition of the Alaskan Way Viaduct in Seattle. The structure, already considered seismically vulnerable, was replaced by the SR 99 tunnel to improve safety.

Since 2001, seismic retrofitting has been a priority for bridges, schools and other essential infrastructure across the state. Washington also implemented the ShakeAlert Earthquake Early Warning System, which sends real-time alerts to residents seconds before a quake strikes, potentially saving lives.

The threat of future quakes

Experts warn that while the Nisqually earthquake was a wake-up call, the region remains at risk for even more powerful seismic events, including a possible megathrust quake from the Cascadia Subduction Zone.

What they're saying:

"The public should be prepared all of the time for the possibility of an earthquake," said Dr. Harold Tobin, director of the Pacific Northwest Seismic Network, in 2021.

Scientists emphasize the importance of personal preparedness, including emergency kits, securing heavy furniture and having a family emergency plan.

With earthquakes inevitable in the Pacific Northwest, proactive measures remain critical to mitigating future damage.

Looking ahead

The anniversary of the Nisqually earthquake is a reminder of the destruction it caused, and the progress made in earthquake readiness. As Washington continues to grow, experts urge residents and policymakers to stay vigilant, ensuring that communities are ready for the next seismic event.
