KATU received many reports from viewers in the Portland area who said they felt the 10:35 a.m. temblor.
The initial quake measured 3.5 and was followed by a 2.5., but then the first quake was re-evaluated as a 4.3 - a fairly robust temblor. A 2.3 aftershock struck just before noon.
Quakes are now measured on a "magnitude scale" instead of the Richter Scale, according to KATU News Meteorologist Dave Salesky.

Last year's huge earthquake raised Chile's coast. The quake is still sending aftershocks through the region.
A magnitude 6.8 earthquake offshore of Bío-Bío, Chile, on Feb. 11 sent thousands running for higher ground, the Associated Press reported. That quake triggered at least two dozen aftershocks, including earthquakes of magnitudes 6.0, 5.8 and 5.6, according to the U.S. Geological Survey (USGS). The rumbling continued today with a magnitude 6.6 temblor underwater near Maule, Chile.
"Chile is an active place so we always have a lot of earthquakes going on," said Don Blakeman, a geophysicist with the USGS in Golden, Colo.
That seismic activity is created as one of the Earth's rocky plates dives under another one. Near Chile, the Nazca plate is thrust under the much larger South American plate at a rate of about 2 inches (6 centimeters) per year.
Friday's magnitude 6.8 quake is thought to be an aftershock from the devastating magnitude 8.8 earthquake that struck Concepcion, Chile, last year, said Michael Bevis, a geophysicist at Ohio State University, who has studied how the earthquake last year changed Chile's coast.

"That's a huge earthquake, so it's going to have more aftershocks that last longer," than other, smaller earthquakes, Bevis told OurAmazingPlanet.

There were at least 42 earthquakes in the area within a 24 hour period that started Thursday. Geophysicists said while the temblors have diminished, they are another clue in what may come next at the world's most active volcano.
"Kilauea's summit has been extending, meaning that more magma is coming up to the summit than is going out to the east rift zone," said Jim Kauahikaua, the observatory's scientist in charge. That means there's move lava underground that's headed toward the actual Kilauea caldera, rather than the zone where most of the activity has been in the volcano's 28 year long eruption.
According to Kauahikaua, the extension of the crater has been going on for a few months.
"This extension of the summit is also reflected in the rise in lava in the Halemaumau vent," he said.
"All of them are indications that pressure is increasing in the magma chamber below the summit."
