The earthquake locations and magnitudes cited in these bulletins are very preliminary, and may disagree with the more accurate USGS locations and magnitudes computed using more extensive data sets.

No tsunami warnings have been issued at this time.

If the preliminary depth measurements hold up, this would be an extremely deep earthquake, which often means less damage than an event of this size near the surface.
