"A 5.8-magnitude earthquake struck off the coast of Oregon late Monday, followed by a swarm of smaller quakes that continued into Tuesday. The US Geological Survey reported the first tremor at 10:30pm local time (1:30am ET), about 102 miles west-southwest of Port Orford. At least five additional quakes have been recorded in the same area, the strongest measuring 4.9 magnitude."
"'This event is identified as the potential mainshock of an earthquake sequence,' the USGS said in its notice of the original larger quake. The agency estimated a six percent chance that one or more aftershocks stronger than magnitude 5 could strike in the next week, powerful enough to cause damage. Smaller tremors are more likely, with as many as 50 aftershocks of magnitude 3 or higher expected, strong enough to be felt in the region."

The agency identified the event as a potential mainshock and estimated a six percent chance of aftershocks stronger than magnitude 5 within a week. Up to 50 aftershocks of magnitude 3 or higher are expected and could be felt locally. The quake occurred hours after Oregon implemented stricter seismic safety rules for state-owned buildings, including upgrades for existing structures by 2060.
