A magnitude 4.1 earthquake shook Molokai Friday afternoon, but there were no reports of major damage and no tsunami was generated.
According to the U.S. Geological Survey, the quake occurred at 4:42 p.m. and was centered in West Molokai, eight miles west-southwest of Kualapuu.
Initial estimates had the quake centered offshore about nine miles north of Molokai.
"My little dog started to growl," said Julie Lopez of Kalae. "The whole house shaking. I stood up to get out of the house and it was still shaking."
The U.S.G.S. Hawaiian Volcano Observatory said the depth of the earthquake was calculated to be shallow, less than one kilometer (0.6 mile), but determining accurate earthquake locations and depths in the request because there are very few seismometers on Molokai and adjacent islands. More sophisticated analysis will likely result in the earthquake being located at a greater depth.
The temblor was felt across the entire island, as well as parts of southeast Oahu and much of West Maui. The U.S.G.S. said there was one report of minor property damage in West Maui.
The H.V.O.'s seismic records show that there have been five earthquakes with magnitudes greater than 4 north of Molokai in the last 25 years. Those quakes, along with Friday's quake, were most likely as a result of the Earth's crust and mantle adjusting due to the weight of the islands on top of it.
Earthquakes with magnitudes 6.4, 6.8, 6.4 and 6.5 occurred in the Molokai region in 1870, 1871, 1895 and 1894, respectively, according to the H.V.O.
