An Oregon earthquake hit the Portland area Sunday night. A 3.3-magnitude quake was recorded about five miles northwest of Sherwood and felt at 8:45 p.m. No reports of injuries or damages were reported, according to an OregonLive report April 7.

The U.S. Geological Survey (USGS) got 1,200 reports from people who felt the quake's impact, with most of those coming from the Beaverton area. Others felt the shaking as far away as Sandy and Battle Ground. The event was 12.1 miles below the surface.

After the 8.2-magnitude earthquake happened in Chile last week, Oregon state geologist, Vicki McConnell said Oregon has a 30 percent chance of getting the same seismic event within the next 50 years. This was in a report by Portland's KGW before the Oregon earthquake even occurred Sunday.

McConnell also said there's a 15 percent chance of getting Oregon getting a magnitude 9 quake in the next 50 years. This is all expected to happen along the Cascadia subduction zone. She said the Chile quake also took place in the subduction zone, but that doesn't mean a big Oregon earthquake is next.

Is Oregon ready for a big quake? The Pacific Northwest is prime earthquake territory and it's unknown when suddenly an 8 or 9-magnitude will strike.
