UPDATE: No Tsunami Threat Following 4.1M Kilauea EarthquakeFebruary 12, 2016, 9:47 AM HST (Updated February 12, 2016, 11:12 AM)

Did you feel Friday’s earthquake? Within two hours of Friday’s 4.1 magnitude quake, the United States Geological Survey received 179 felt reports on its “Did you Feel it?” website. The majority of those felts reports came from the Hilo area, totaling 70 reports. Another 25 individuals reported feeling the earthquake in Pahoa, 23 in Kea’au, 17 in Mountain View, 12 in Volcano, and 9 in Kurtistown.
Hawaiian Volcano Observatory notes that the earthquake reached a IV on the Mercalli Intensity Scale, as reported by Big Island residents, which notes that light shaking occurred.
HVO also reports that no aftershocks occurred following the 4.1 magnitude earthquake.
“HVO monitoring networks have not detected any significant changes in activity at the summit or along the rift zones of Kilauea or at other Hawaiian volcanoes resulting from the earthquake,” said HVO Scientist-in-Charge Christina Neal.
HVO geologists working near the Puʻu ʻŌʻō cone this morning reported feeling the earthquake, but noted no change in the eruption.
The south flank of Kilauea has been the site of 28 earthquakes of a magnitude 4.0 or greater in the past 25 years. HVO officials say most of the earthquakes are caused by abrupt motion of the volcano’s south flank, which moves to the southeast over the oceanic crust as a result of magma being injected into the East Rift Zone.
The location, depth, and waveforms recorded as part of today’s earthquake are all consistent with slip along this south flank fault.

The Pacific Tsunami Warning Center says there is no tsunami threat to Hawai’i following a 4.1 magnitude earthquake that occurred on the south flank of Kilauea.
According to PTWC, the earthquake occurred Friday at 9:25 a.m. Hawai’i time.
Initially, the earthquake was listed as a 4.0 magnitude, but was upgraded to a 4.1 magnitude.
United States Geological Survey officials say the earthquake was located 12 miles southwest of Leilani Estates, 18 miles south-southwest of Hawaiian Paradise Park, 27 miles south of Hilo, 66 miles east-southeast of Kailua-Kona, and 227 miles southeast of Honolulu.
Hawaiian Volcano Observatory did not release information connecting the earthquakes with volcanic activity.
