Real-time coverage of earthquake event — 154 km WSW of Pistol River, Oregon — Pandita Data.
🌍 OPEN LIVE 3D EARTHQUAKE MAPA magnitude 5.7 earthquake struck 154 kilometers west-southwest of Pistol River, Oregon on June 3, 2026 at 10:53 UTC, with a shallow depth of 10 kilometers. The USGS recorded 38 felt reports across the region. No tsunami warning was issued, and the PAGER alert system assigned a GREEN rating, indicating minimal anticipated damage. This moderate-magnitude event occurred within the Cascadia Subduction Zone complex, a tectonically active region where the Juan de Fuca Plate descends beneath the North American Plate at a rate of approximately 1.6 centimeters per year.
The earthquake occurred in the offshore Cascadia region, one of North America's most seismically significant zones. The Juan de Fuca Plate subducts along the Cascadia Subduction Zone, generating both interplate megathrust earthquakes and intraplate events within the descending slab. This particular event likely represents an intraplate rupture within the subducting Juan de Fuca Plate, a common occurrence in this region. Historical records and paleoseismic evidence indicate that Cascadia produces megathrust earthquakes exceeding magnitude 8 every 200–800 years, with the last major event occurring in January 1700.
At magnitude 5.7 with a 10-kilometer depth, this earthquake released approximately 1.4 × 1018 joules of energy—equivalent to 335 kilotons of TNT. The shallow focal depth amplifies ground shaking intensity near the epicenter but limits regional propagation. Shallow ruptures typically produce higher-frequency seismic waves that attenuate rapidly with distance, explaining the limited felt reports despite the moderate magnitude. The rupture likely propagated through brittle oceanic crust under extensional stress within the subducting slab.
Earthquakes shallower than 30 kilometers produce intense ground acceleration near the epicenter. This event's 10-kilometer depth placed maximum energy release in the upper crust, causing stronger shaking in nearby offshore areas and the southern Oregon coast. However, shallow ruptures dissipate energy more rapidly than deep events, reducing felt reports at greater distances. No tsunami was generated because the rupture occurred in a subducting oceanic plate, not at the megathrust interface where vertical seafloor displacement occurs.
Pistol River, Oregon and nearby coastal communities including Port Orford and Gold Beach experienced perceptible shaking. The sparsely populated offshore epicenter limited direct impacts. However, this event reinforces the importance of earthquake preparedness throughout the Pacific Northwest, a region vulnerable to future megathrust ruptures and tsunami generation. Historical seismic hazard assessments indicate a 15 percent probability of a magnitude 8.0+ Cascadia megathrust earthquake within the next 50 years. Continued monitoring of intermediate-depth events provides critical data on slab stress conditions and subduction zone behavior.
Real-time seismic data and 3D rupture simulations are available through Pandita Data's earthquake module, which visualizes fault geometry, stress release, and wave propagation across the Cascadia Subduction Zone. Use these tools to understand your region's seismic hazards and build community resilience.
