Warnings across two US states as multiple earthquakes rock West Coast,
Multiple strong earthquakes right off the West Coast have sent shockwaves across two states Wednesday morning.
The US Geological Survey has detected three earthquakes less than 100 miles from the coast of California and Oregon, all setting off emergency alert signals in the area.
The first alerts were sent out after detecting a magnitude 5.7 earthquake in the Pacific Ocean at 6.53am ET (3.53am local time).
The seaquake’s epicenter was roughly 100 miles from the West Coast, with residents in both states reporting shaking as the large tremor struck the shore.
Multiple coastal communities from Eureka, California to Reedsport, Oregon, about 240 miles north, felt the tremors.
That seismic event was followed by a magnitude 5.1 earthquake at 8.45am ET. It struck just 55 miles from Eureka, a city of more than 25,000 people in the northern part of the state.
The third quake, this one registering at 4.5 in magnitude, erupted in the Pacific in the exact same spot as the second quake did 26 minutes later.
USGS confirmed that their ShakeAlert Earthquake Early Warning system was activated by the quakes, sending out automatic warnings to thousands of people’s phones and digital devices.
This is a breaking story. More details to follow.
USGS has recorded two strong earthquakes over 5.0 in magnitude Wednesday morning near the US West Coast
The city of Eureka, California felt the shockwaves from both seismic events. Eureka has a population of approximately 25,000 people
It also notified emergency agencies, including emergency management offices in both California and Oregon, so they could check on things right away.
Officials noted that there have been no tsunami warnings issued despite the close proximity to the West Coast.
USGS has noted that there is a nearly 60 percent chance of another quake stronger than 3.0 striking the West Coast within the next 24 hours.
The area under and near Eureka is one of the most seismically active regions in the continental US.
