How strong was this earthquake?

Moderate earthquakes can damage poorly built or unreinforced structures near the epicentre, while well-engineered buildings typically escape serious harm. Shaking is often strong enough to wake sleeping residents over a wide area.

A magnitude 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 433, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.

When it happened locally

That is about 16:57 local solar time at the epicentre, during the afternoon.

This event was deeper than 69% of the 154,026 earthquakes recorded in the United States in our catalogue and stronger than 100% of them.

Where was the epicentre?

The epicentre was located at 43.9019, -128.2040. The closest other recorded event was a magnitude 4.0 earthquake 9 km northwest of here on 04 August 2026.

The nearest other settlements in our records are Barview (113 km east), Langlois (161 km east-southeast), Bandon (169 km east-southeast) and Port Orford (192 km south-southeast).

Why the 10 km depth matters

At 10 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size can be felt widely and may cause minor local damage. Its shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.

What does the tsunami information flag mean?

The USGS event record links to NOAA tsunami information because this was a large event in an oceanic region. That link flag does not mean a tsunami occurred or that a warning is active. Check tsunami.gov and instructions from your local authority for the current status of your coastline.

Aftershocks and local seismic history

No further earthquakes have been recorded within about 150 km of the epicentre since this event was recorded.

35 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.0 event near Bandon on 16 January 2026. This M5.3 event released about 11 times less energy than that event.

31 earthquakes have been recorded within 100 km of this epicentre in the past year, 4 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near off the coast of Oregon?

It measured magnitude 5.3 — a moderate earthquake. A magnitude 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

How deep was the earthquake near off the coast of Oregon?

The focus was 10 km below the surface, which counts as shallow.

Was the off the coast of Oregon earthquake felt at the surface?

At magnitude 5.3 and a focal depth of 10 km, shaking would have been concentrated near the epicentre.

When did the earthquake near off the coast of Oregon happen?

07 September 2026 at 01:30 UTC.

Was there a tsunami?

The USGS record carries a link to NOAA tsunami information for this event. That is not a warning: check your regional tsunami warning centre for any live alert.

Have there been aftershocks?

No further earthquakes have been recorded within about 150 km of the epicentre since this event was recorded.

How often do earthquakes happen near off the coast of Oregon?

35 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.0 event near Bandon on 16 January 2026. This M5.3 event released about 11 times less energy than that event.
