The catalog location label is off the coast of Oregon; no separate nearest-city field was supplied with this solution. By catalog depth, this is a shallow event. The magnitude-derived energy estimate is 5.62e+12 joules, or about 1,344 tons of TNT equivalent; that calculation describes source energy, not local damage.

1 public felt report is attached to the current catalog entry. Other attached observation fields include catalog significance score 432. No official casualty or damage statement is attached to the normalized event evidence.

The USGS Week catalog currently marks the solution as reviewed. No station-count, phase-count, residual, gap, or uncertainty fields were supplied in the normalized record. 1 alternate network solution is retained for comparison.

The provider record carries a tsunami-related flag. That field is not itself a warning; readers should check the issuing tsunami warning center and local officials. Magnitude, depth, and location can change as monitoring networks add observations and review the solution.
