Over the past 24 hours, 3 moderate-to-major earthquakes and 1 tsunami occurred.  Station E1TX was able to detect 2 of 3 earthquakes, ironically the closest event was the one not recorded!  Shown below is a current screen capture from the EQ1 seismograph TXESP operates.

  1. A strong M6.4 earthquake in the Northern Mariana Islands at 08/28/2018, 22:35 hrs UTC and 60kms deep (detected)
  2. A small M4.4 earthquake in La Verne, CA  at 08/29/2018, 02:33 hrs UTC and 5kms deep.  This California earthquake may have a small magnitude, but it was lightly felt across most of Los Angeles (NOT detected)
  3. A MAJOR M7.1 earthquake in New Caledonia at 08/29/2018, 03:51hrs UTC and 27kms deep. (detected)This event **did** generate a very small 1 ft tsunami in the South Eastern Pacific Ocean.
