The 4.1-magnitude earthquake at 5:52 a.m. off the Windward coast of Oahu is rare, said seismologist Stuart Koyanagi with the U.S. Geological Survey’s Hawaii Volcano Observatory.
The quake’s epicenter was estimated to be about 19 miles east-northeast from Kaaawa and 4.4 miles deep.
Koyanagi said the observatory received about a dozen reports from Kailua and Kaneohe yesterday morning. If it was deeper, it would usually be felt in a wider area, but the intensities would be lower.
