The shallow quake was recorded at 7:31 p.m. PST Tuesday more than 150 miles west of southern Oregon. It did not generate a tsunami.

Within about an hour, the information center’s website recorded 39 reports of people who reported feeling the quake. Most were in northern California and southern Oregon and characterized it was "weak" or "barely felt."

U.S. Geological Survey geophysicist Dale Grant told The Associated Press in a telephone interview that the quake occurred in a seismically active area and was "not uncommon at all."

In his words, "These are the ones we like — nobody gets hurt and there’s no damage."
