If you’re in Washington State today, July 31, 2025, you might still be hearing about the tsunami advisory that swept the coast last night. A massive 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula sent shockwaves across the Pacific, triggering alerts from Japan to Hawaii—and yes, right here in Washington. While the advisory has since been canceled, the event was a stark reminder of how vulnerable our coastline is to distant disasters. Let’s break down what happened, what it means for Seattle and the outer coast, and where you can find the latest maps and updates.

The Tsunami’s Journey to Washington’s Coast
The earthquake struck near Russia’s Kamchatka Peninsula, a hotspot for seismic activity, early on July 30. Within hours, tsunami waves rippled across the ocean, reaching Japan and Hawaii before arriving on the West Coast. Washington’s outer coast—places like La Push, Neah Bay, and Long Beach—was under a tsunami advisory by Tuesday evening, meaning strong currents and unpredictable waves were expected, even if the surge wasn’t towering.

Waves began hitting Washington’s shores just after midnight, with La Push seeing a 1.3-foot surge around 4 a.m. and Port Angeles recording 1.2 feet. These might sound small, but the National Weather Service stressed that even six inches of fast-moving water can knock someone off their feet, and two feet can sweep away cars. The advisory urged people to stay off beaches and out of harbors, where swirling currents could turn docks into danger zones.
Timing varied by location: Long Beach saw waves around 11:45 p.m., Westport by 11:55 p.m., and Port Townsend by 12:45 a.m. Thankfully, the waves stayed below forecasted heights, and by Wednesday morning, the advisory was lifted. But experts like UW’s Professor Harold Tobin warned that the open Pacific coast, from Neah Bay to Grays Harbor, would’ve been the most at risk if the tsunami had packed a stronger punch.
Seattle’s Close Call and How to Stay Prepared
If you’re in Seattle, you might be wondering: Was the city ever in real danger? The short answer: not this time. The National Weather Service confirmed that inland waters like Puget Sound were spared, with no expected impacts. Tsunamis lose energy as they funnel into narrower spaces, and Seattle’s geography offers some natural protection. However, Professor Tobin noted that harbors and marinas could still see surges, so caution was key.

This event was a “distant tsunami,” meaning we had hours of warning. But Washington’s bigger threat is a local tsunami from the Cascadia Subduction Zone, a fault line capable of a magnitude 9.0 quake that could send devastating waves to the coast in minutes. That’s why knowing evacuation routes is critical. The Washington Geological Survey provides detailed tsunami hazard maps, showing which areas are most at risk. For example, Ocean Shores and Westport have designated evacuation zones marked by blue-and-white signs.
Western Washington Tsunami Advisory will continue until further notice, need wave heights to subside. Port Angeles and La Push showing recent increased waves (~1′). Main message, stay out of dangerous waters (currents, waves) and off beaches. NWS Seattle on top of this. #WAWX pic.twitter.com/1z5quyK7Vb

If you’re planning a coastal trip, bookmark the Tsunami Warning Center’s real-time updates and check local county emergency sites for evacuation maps. After yesterday’s alert, officials reiterated: Don’t be a “tsunami tourist.” Waves can arrive for hours, and the first one isn’t always the biggest. In Japan’s 2011 disaster, the fifth wave was the most destructive.

The Bottom Line
While Washington dodged a major threat this time, the 2025 Russian earthquake was a wake-up call. Tsunamis are unpredictable, and our coast will face another one, whether from across the Pacific or right off our shore. Stay informed, know your zone, and remember: when the earth shakes near the coast, head for high ground immediately. For today, though, you can breathe easy—just keep an eye on those alerts.
