(NEXSTAR) – A “notable” earthquake registering at a magnitude of 4.5 struck Washington State on Monday morning, according to the United States Geological Survey.
The quake’s epicenter was located near the San Juan Islands, near the Canadian border in the northwest corner of the state.
A geophysicist at the Washington Geological Survey, in an email to Nexstar, said the event originated “around 10 miles down” in the Earth’s crust.
“It did not coincide with any known active fault in the area. Earthquakes of this size and depth occur frequently in the Salish lowland,” said Megan L. Anderson of the Washington Geological Survey, an office of the Washington Department of National Resources.
Anderson added that it’s “unlikely that any damage or injuries were sustained,” as a 4.5-magnitue earthquake falls under the threshold (5.5) at which such incidents generally occur.

The USGS currently forecasts the chances of a magnitude 3 or greater aftershock at 43% for the next week. Chances of aftershocks with greater magnitudes are much less likely, according to the agency.
Monday morning’s earthquake in Washington comes after an earthquake with a preliminary magnitude of 3.9 rattled Los Angeles only the night before. There were no immediate reports of injuries or damage.
