One aftershock with a 4.0 magnitude hit at 5:26 a.m., 12 miles from Kawaihae at a depth of 18.3 miles.

A 3.5 magnitude aftershock struck at 6:57 a.m. about 13 miles from Kawaihae at a depth of 27 miles.

Since 8:20 p.m. Monday, the Big Island has been hit with eight aftershocks, according to the U.S. Geological Survey. The smallest — with a magnitude of 2.0 — struck at 2:21 this morning seven miles west-southwest of Waikaloa.

As of 9:30 this morning, there have been 78 aftershocks of magnitude 2.0 or greater since Sunday, said Jim Kauaihikaua, scientist in charge of the U.S. Geological Survey Hawaiian Volcano Observatory.

"It suggests the aftershocks aren't over," Kauaihikaua said. "We're keeping an eye on it but they're getting more infrequent and will just continue to peter out."

A separate earthquake of 2.0 magnitude also hit at 9:44 a.m. on the Hilo side of the Big Island at Pee'ekeo.

Stuart Weinstein of the Pacific Tsunami Warning Center said the 4.0 aftershock at 5:26 a.m. set off a warning bell at the center in 'Ewa Beach.

There were no immediate reports of damage associated with any of the aftershocks.

An area off the northwest coast of the Big Island continued to rumble with two noticeable earthquake aftershocks this morning, one of which was felt as far away as O'ahu.
