The Associated Press - A 4.5-magnitude earthquake struck the north part of Hawai'i Island on Wednesday, Oct. 19, and the shaking was followed by a series of smaller temblors. The first quake struck 13 miles southeast of Waimea at about 2 p.m., the U.S. Geological Survey said. It was centered at a depth of 11.7 miles. About two-dozen smaller quakes ranging in magnitude from 1.7 to 3.6 followed within two hours.
No tsunami alert was issued, and there were no immediate reports of damage.
Residents across the island reported feeling light to moderate shaking. Over the past 25 years, the north flank of Mauna Kea has experienced 10 earthquakes greater than magnitude 4.0, including last week's event at depths of six to 25 miles. Deep earthquakes in the region are most likely caused by structural adjustments within the Earth's crust due to the heavy load of Mauna Kea, according to the USGS Hawaiian Volcano Observatory.
