No tsunami expected after 5.1 Kīlauea earthquake on Hawaiʻi Island
There is no tsunami expected following a 5.1 (4.9 preliminary) magnitude earthquake reported at around 5:54 p.m. on Monday, Dec. 4, in the Hilina Region of the Kīlauea volcano on Hawaiʻi Island.
The Pacific Tsunami Warning Center reports that there is no action required and no tsunami expected; however, some areas may have experienced shaking.
The earthquake was related to “shallow movement on the pali system of Kīlauea volcano’s south flank and is not directly related to volcanic activity,” according to the USGS Hawaiian Volcano Observatory.
One magnitude-3 aftershock occurred. “Aftershocks will likely continue, some large enough to be felt locally,” according to the HVO.
HVO scientists say they observe no detectable changes in activity at Kīlauea as a result of these earthquakes.
The earthquake occurred at a depth of 1 mi below sea level. The USGS reports that nearby places to the earthquake includes:
- Volcano, 8.5 mi NNW
- Hawaiian Paradise Park, 24 mi NE
- Hilo, 29.1 mi NNE
- Kailua-Kona, 56.3 mi WNW
- Honolulu, 220 mi NW
Within the first half-hour of the quake, there were 27 people who reported feeling the earthquake in Hilo on Hawaiʻi Island, and 24 people who reported feeling the quake in Kailua Kona.
