There is NO tsunami threat to Hawaiʻi after a preliminary magnitude 7.1 earthquake in Central California at 8:20 p.m. (5:20 p.m. Hawaiʻi time) on Friday, July 5, 2019.

The Pacific Tsunami Warning Center says that based on all available data, there is no tsunami threat to Hawaiʻi.

The USGS reports that the quake was centered:

  • 10.6 mi NNE of Ridgecrest, California;
  • 49.0 mi NNE of California City, California;
  • 64.5 mi NE of Tehachapi, California;
  • 68.1 mi NNW of Barstow, California; and
  • 248.4 mi NNW of Mexicali, Mexico.

The Western States Seismic Policy Council issued a Tweet this evening saying “Yesterday’s earthquake has been followed by this evening’s quake. That tells us yesterday’s was technically a ‘foreshock.'”

According to the USGS, “foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs.”

Check back for further details, which will be posted as they become available.
