PORTLAND, Ore. — An earthquake hit off the Oregon coast Tuesday morning, according to the United States Geological Survey.

The 4.0 magnitude quake was recorded at 5:43 a.m., about 120 miles west of Bandon, KOIN-TV reported.

In the last three weeks, eight small earthquakes have been recorded in the general area. Most were near the Blanco fault zone.

The fault zone is a common place for earthquake swarms. Last December, more than 50 earthquakes rumbled off the coast in that area within 24 hours.
