A 4.2 magnitude earthquake was reported at 2:01 a.m. HST on Sunday, July 30, 2017, about 16 miles SE of Kaupō, Maui in the ‘Alenuihāhā Channel between the Islands of Maui and Hawaiʻi. In relation to Hawaii Island, the quake was 21 miles northwest of Hāwī, Hawaiʻi, and occurred at a depth of 11 miles.

The USGS reports that the quake was also located: 16 miles S of Pukaauhuhu, Hawaiʻi; 33 miles SE of Kīhei, Maui; 41.2 miles SE of Kahului, Maui; 42.5 miles SE of Wailuku, Maui; and 129.4 miles ESE of Honolulu, Oʻahu.

Seismic Network Manager Brian Shiro with the US Geological Survey’s Hawaiian Volcano Observatory says the earthquake was likely due to bending of the oceanic plate from the weight of the island and poses no significant hazard.

The Pacific Tsunami Warning Center issued a statement saying there was no tsunami generated, which also had no apparent effect on Kīlauea Volcano’s ongoing eruptions.

The USGS Did you feel it? website received nearly 100 felt reports within an hour of the earthquake.

The HVO reports that “the maximum intensity of shaking reported by residents on the islands of Hawaiʻi, Maui, Moloka‘i, and O‘ahu and computed by the USGS ShakeMap was III on the Modified Mercalli Intensity Scale, indicating light shaking.”

On another note, earlier this week, the HVO compiled a detailed report on the 5.3 magnitude earthquake reported on June 8, 2017 off the southern flank of the Kīlauea Volcano, calling the incident the “largest earthquake to strike Hawaiʻi in over a decade.” The HVO reported that the location and depth of the June earthquake are consistent with slip along or above this south flank fault.
