When will we know if there will be an earthquake?
WASHINGTON — The National Weather Service has declared an earthquake in the Pacific Northwest, just hours after the quake struck.
A magnitude 6.7 earthquake occurred near the city of Washingtonton and a magnitude 7.1 quake occurred about 30 miles east of Spokane, according to the National Weather Center.
The earthquake was the strongest to hit the region in about two years, the weather service said.
The U.S. Geological Survey has said the quake was caused by a magnitude 6 or greater earthquake.
A small number of people were injured.
A few hours after Tuesday’s quake, a small tsunami warning was issued in the area.
