A light quake with the magnitude of 4.7 struck the area of north of Hawaii Island’s Hamakua Coast at 11:16 p.m. Thursday (March 31) according to the United States Geological Survey.
According to the USGS’s ‘Did You Feel It’ website the temblor was widely felt on the island with reports coming in from Volcano, Naalehu, Hilo, the Hamakua Coast, West Hawaii and throughout the state from Maui County, Oahu and Kauai.
There is no tsunami expected from this light earthquake.
USGS: How large does an earthquake have to be to cause a tsunami?
Magnitudes below 6.5
Earthquakes of this magnitude are very unlikely to trigger a tsunami.Magnitudes between 6.5 and 7.5
Earthquakes of this size do not usually produce destructive tsunamis. However, small sea level changes may be observed in the vicinity of the epicenter. Tsunamis capable of producing damage or casualties are rare in this magnitude range but have occurred due to secondary effects such as landslides or submarine slumps.Magnitudes between 7.6 and 7.8
Earthquakes of this size may produce destructive tsunamis especially near the epicenter; at greater distances small sea level changes may be observed. Tsunamis capable of producing damage at great distances are rare in the magnitude range.Magnitude 7.9 and greater
Destructive local tsunamis are possible near the epicenter, and significant sea level changes and damage may occur in a broader region.Note that with a magnitude 9.0 earthquake, the probability of an aftershock with a magnitude exceeding 7.5 is not negligible. To date, the largest aftershock recorded has been magnitude 7.1 that did not produce a damaging tsunami.
