A magnitude 4.2 earthquake struck the Puget Sound region on Tuesday afternoon, centered near Wauna, Washington. The tremor was widely felt across the region, including in Seattle, Tacoma, and Olympia, but no injuries or significant damage were reported. The U.S. Geological Survey estimates a 37% chance of a magnitude 3 aftershock within the next week.

Key points

  • The earthquake occurred at 2:05 p.m. on September 29, 2026, with an epicenter located approximately 3.7 to 5 kilometers west-northwest of Wauna, near Gig Harbor and Port Orchard.
  • The quake had a depth of roughly 16.7 to 17.3 miles and was felt across a wide area, including Seattle, Bremerton, Tacoma, Olympia, and Issaquah.
  • More than 6,000 people reported feeling the shaking, with the majority describing the intensity as 'weak' or 'light.'
  • No injuries or structural damage were reported by local fire and police departments in Pierce County, Tacoma, or the Key Peninsula.
  • The USGS estimates a 37% chance of a magnitude 3 or higher aftershock within the next week and an 8% chance of a magnitude 4 or higher aftershock.

Background

The Puget Sound region has experienced seismic activity before, most notably the 2001 Nisqually earthquake. The current event is part of the ongoing tectonic activity in the Pacific Northwest. The region has also faced economic challenges, including job losses, which may influence public perception of infrastructure resilience.

How outlets are covering it

KOMO News and KUOW reported the earthquake's magnitude and location, with KUOW noting that Seattle City Council paused a meeting due to the quake. MyNorthwest.com emphasized the widespread feeling of the tremor, citing residents in Lacey and Seattle, and noted Sound Transit's 1 Line disruptions. The Tacoma News Tribune focused on the lack of damage and reported on residents' experiences, including a 'deep growl' and shaking for about 10 seconds. All sources agreed on the magnitude and the lack of significant damage, but differed in their emphasis on the regional impact and public response.

Why it matters

The earthquake highlights the ongoing seismic risks in the Puget Sound region and the importance of preparedness. While no damage was reported, the widespread feeling of the tremor and the potential for aftershocks underscore the need for continued monitoring and public awareness.

What to watch

The USGS will continue to monitor for aftershocks, and local authorities will remain on alert for any reports of damage or injuries. The public is advised to stay informed through official channels and to be prepared for potential aftershocks.
