This has the distinct signature of a pre quake to me, expect another within 24 hours, same place, only with 30% higher magnitude, that would make it at least a Mag 7.  A Tsunami would likely happen with a Mag 7.  If my memory is working well, one of the Chilean Mag 8's was also preceeded by a Mag 5.5, and it was three days after a Solar filament let loose, and right on the Lunar Tidal Stress day.
  I wouldn't plan any camping trips to the Beach this summer, especially in Oregon.

I agree with pre-quake reasoning, M.  We'll not be clear of this risk for about a week.

The dreads have slacked off quite a bit....the headache is gone.

But the Oregon coast event still looks pre-quake, and we aren't done yet.

Major quake rattles Chile but no serious damage
Alexandra Ulmer

SANTIAGO (Reuters) - A major quake hit central Chile on Sunday, rattling buildings and temporarily triggering a coastal evacuation on fears of a tsunami, but there was no serious damage and big mines in the world's top copper producer were operating normally.

Residents in Chile's capital, Santiago, fled their homes as the tremor rattled television sets, kitchen cabinets and tables, and a mayor in the town of Parral in south-central Chile told local radio a 74-year-old woman died of a heart attack due to the quake. There were no reports of serious casualties.

The 7.1 magnitude quake struck 16 miles north- northwest of the town of Talca at a depth of 22 miles at 7:37 p.m. local time (5.47 p.m. EDT), the U.S. Geological Survey said, revising down an initial magnitude of 7.2. The tremor struck 136 miles from Santiago, home to about a third of Chile's population of 17.2 million people.

It was one of the strongest quakes to hit Chile since a massive 8.8 temblor devastated the south-central region in early 2010, which triggered tsunamis, killed about 500 people and hammered roads and infrastructure.

The government lifted a preventive evacuation order just before midnight, after about 7,000 people were ordered to evacuate the Maule region's coast due to signs the sea had retreated a bit, Chilean Health Minister Jaime Manalich said. No tsunami alert was issued.
