No tsunami threat following 4.3 earthquake on Big Island

KILAUEA VOLCANO, BIG ISLAND (HawaiiNewsNow) -

A magnitude-4.3 earthquake struck near the summit region of the Kilauea volcano on the Big Island Monday morning, but it was not strong enough to generate a tsunami warning to the state, according to the Pacific Tsunami Warning Center.

According to Wes Thelen, HVO's Seismic Network Manager, the earthquake was centered about 5 miles west-southwest of the summit of Kilauea and at a depth of approximately 8 miles.

As of 10 a.m., five aftershocks of the magnitude-4.3 earthquake have been recorded. The strongest of these aftershocks has been magnitude-1.

During the past 25 years, there have been two earthquakes in this same general area with magnitudes greater than 3.0 and depths of 10–20 km (6–12 mi). Today's earthquake could lie on the fault that marks the boundary between Mauna Loa and Kilauea, or it could have occurred on a reactivated fault within the old oceanic crust upon which the Island of Hawaii is built.

The earthquake has caused no detectable changes on Kilauea or other active volcanoes on the Island of Hawaii.

No damages have been reported.
