PORTLAND, Ore. -- A magnitude 5.9 earthquake hit off the Oregon coast Wednesday afternoon. Officials with the West Coast and Alaska Tsunami Warning Center said there was no tsunami concern.
The 9-mile-deep earthquake hit 271 miles to the southwest of Portland at 3:42 p.m. Wednesday. It's just one of more than 100 earthquakes the Pacific Northwest sees each year.
For example, earlier this week a small quake was recorded 18 miles west of Walla Walla, Wash. That was Monday night.
The National Earthquake Information Center recorded it as a magnitude 3.5 earthquake, at a depth of about eight miles. By late Monday night, the center's website had received only one report from a resident who felt the quake.
Doug Gibbons of the U.S. Geological Survey says the earthquake is not related to two massive earthquakes in Indonesia on Wednesday. Are you prepared?
As it so happens, Oregon is recognizing April as "Earthquake and Tsunami Awareness Month." Throughout the month, schools are practicing mandated drop-cover-and-hold drills.
And experts we talked to say that's a good thing.
On Wednesday alone, a earthquake hit Mexico -- causing tall buildings to sway and people to be evacuated. The two earthquakes in Indonesia measured more than 8 in magnitude and led to massive evacuations across southeast Asia. At least one hotel guest was slightly hurt when he jumped out of a window, but no deadly waves nor serious damage was reported.
Scientists say, at some point, it will be Oregon.
