A 4.5 magnitude earthquake struck Washington state on Wednesday, July 1, 2026, and was felt across parts of southern British Columbia, according to the U.S. Geological Survey (USGS). The quake occurred at approximately 1:21 p.m. EDT, with its epicenter located near the town of Forks, Washington, about 300 kilometers southwest of Vancouver. There were no immediate reports of damage or injuries in either Canada or the United States.
Details of the Earthquake
The USGS reported that the earthquake had a depth of 10 kilometers, typical for shallow quakes in the region. Shaking was felt in Vancouver, Victoria, and other communities in the Lower Mainland, as well as on Vancouver Island. Residents described a brief, rolling sensation that lasted several seconds. The Pacific Northwest Seismic Network noted that the event was not followed by any significant aftershocks as of Thursday morning.
Seismic Context and Preparedness
This earthquake comes amid heightened awareness of seismic risks in the Cascadia subduction zone, which stretches from northern California to British Columbia. While this quake was not related to a major subduction event, it serves as a reminder for residents to prepare for larger earthquakes. Emergency Management BC stated that they are monitoring the situation and encouraged residents to review their emergency plans.
According to the USGS, earthquakes of this magnitude occur several times a year in Washington state, but they are often too small to be felt widely. The July 1 event was notable for its broad felt area, which included parts of Oregon and Idaho as well.
Impact and Response
No infrastructure damage or service disruptions were reported. BC Hydro confirmed that power grids were unaffected, and transportation authorities reported no issues with bridges or roads. The Vancouver International Airport operated normally. Social media posts from residents in Vancouver and Victoria described the shaking as mild, with some comparing it to a passing truck.
“It was just a gentle wobble, nothing scary,” said one Vancouver resident on X. The USGS received over 1,000 felt reports within the first hour, with the majority coming from Washington state and British Columbia.
