A small earthquake rocked the submarine volcano of Loihi early today and posed no tsunami threat to the rest of the state.

The magnitude-3.8 temblor struck at 3:10 a.m. well inside the seamount, 22 miles southeast of Pahala, Hawaii island.

The epicenter was 26.5 miles deep, according to the U.S. Geological Survey.

The quake was felt in Naalehu, Captain Cook, Kailua-Kona, and Kihei, Maui, the USGS reported.

The active volcano, which sits on the submarine flanks of Mauna Loa, rises to within 3,000 feet of the ocean’s surface.
