Incident: No Tsunami Threat
This is a civil defense message for Friday, May 4, 2018 at 1:40 pm.
The Pacific Tsunami Warning Center reports an earthquake occurred at approximately 12:33
pm today.
This earthquake was not large enough to cause a tsunami for the island of Hawai’i. I say again,
there is no tsunami threat to the island of Hawai’i.
Revised data indicates that the earthquake measuring a magnitude of 6.9 was centered in the
vicinity of the south flank of Kilauea volcano.
This earthquake generated small sea level changes at some locations on the big island.
Measurements include
Hilo 20 cm amplitude
Kapoho 40 cm amplitude
Honuapo 15 cm amplitude
At all locations the fluctuations are now diminishing.
No tsunami is expected. Repeat. No tsunami is expected. However...many areas may have
experienced strong shaking.
This will be the only statement issued for this event unless additional data are received.
As in all earthquakes, be aware of the possibility of aftershocks. If the earthquake was strongly
felt in your area, precautionary checks should be made for any damages; especially to utility
connections of gas, water, and electricity.
If any additional information becomes available, you will be notified. Thank you. This is your
Hawai’i County Civil Defense Agency.
