Series of Earthquakes Shake the U.S. West Coast: Magnitude 5.7 in Oregon and 4.6 in Hawaii

Earthquakes Shake the West Coast

Seismic Activity in California

Mild Tremor in Hawaii

Early Wednesday began with a magnitude 5.7 earthquake in the Pacific Ocean, off the southern coast of Oregon, recorded at 3:53 a.m. local time, according to official data.

The epicenter was located about 159 kilometers west-northwest of Crescent City, California, at a depth of nearly 10 kilometers, although only a small number of residents in coastal communities reported feeling it.

Authorities said there was no need to issue a tsunami warning, reducing immediate concern in the border region between northern California and southern Oregon.

So far, no property damage or injuries have been reported, despite the quake being considered strong on the magnitude scale.

Two Additional Earthquakes Intensify Activity in California

Hours after the first event, a second magnitude 5.1 earthquake was recorded at 5:45 a.m., this time about 88 kilometers southwest of Eureka, California.

It was followed by another magnitude 4.1 tremor about half an hour later in almost the same area, increasing attention on seismic activity in the region.

Both tremors occurred at a depth of less than one mile, which caused them to be felt more clearly in several nearby coastal communities.

Despite the sequence of movements, authorities confirmed that there are no reports of significant damage or major service disruptions, Fox Weather reported.

Hawaii Also Records Seismic Activity This Week

In another part of the Pacific, Hawaii’s Big Island experienced a magnitude 4.6 earthquake Monday afternoon, specifically off the Kona coast.

The movement occurred at 5:58 p.m. local time, with an epicenter located just over 5.6 kilometers from the coast of Kahaluu-Keauhou and 34 kilometers deep beneath the sea.

The tremor was felt across wide areas of the Big Island and in some parts of Maui, although it also did not generate a tsunami warning.

Authorities ruled out any link between the event and volcanic activity or magma movement in volcanoes such as Kīlauea, Mauna Loa, or Hualālai.

Experts Warn About Possible Aftershocks

The recent movement in Hawaii comes weeks after a magnitude 6.0 earthquake recorded on May 22 on the same island, keeping specialists alert.

The U.S. Geological Survey said aftershocks could occur in the coming hours or days, although more serious scenarios are not expected.

Both on the continental West Coast and in Hawaii, seismic activity is part of the natural dynamics of the Pacific Ring of Fire.

For now, authorities continue monitoring the situation while reiterating that no damage or major impacts have been reported from these West Coast earthquakes, Fox Weather noted.
