The earthquake, which struck at 9:33 p.m. local time on Tuesday, was centered in the ocean about 48 kilometers southwest of the coastal town of Tongoy, or 89 kilometers southwest of La Serena. It struck about 19 kilometers deep, making it a shallow earthquake, according to Chile's national seismological agency.
Moderate shaking was felt in the Coquimbo Region, according to Chile's National Office of Emergency of the Interior Ministry (ONEMI). "The characteristics of the earthquake do not meet the conditions necessary to generate a tsunami off the coast of Chile," ONEMI said in an alert. No tsunami warnings have been issued.
Other details were not yet available, but there were no immediate reports of damage or casualties.

Quite normal for Chile.
Don't think this is the planetary alignment quake everyone is waiting for. The portions of Chile that have not slipped in a while are farther north in Chile or offshore Valparaiso. If offshore Valpo, you probably won't be hearing from me for at least a couple of days, if ever again, depending on size and resulting tsunami.
For the planetary configuration shaker, my bet is still on So. Cal. to No. Cal/Pac NW.
