A 4.8 magnitude earthquake shook up the Big Island last night but there were no reports of damage.
The quake, centered about 58 miles south Hilo and 9 miles below the sea-floor, struck at about 11:13 p.m., according to the U.S. Geological Survey.
The USGS initially listed it as a 4.1 magnitude quake, but upgraded its strength after further analysis.
It was felt across the Big Island as far north as Hawi, 158 miles away from the epicenter, according 160 responses from the public compiled by the USGS.
The quake was located near the Lo'ihi Seamount, Hawaii's youngest volcano, on the sea-floor south of Kilauea about 19 miles offshore.
During the past 25 years, 82 earthquakes with magnitudes of 4 or greater have occurred near Lo'ihi, most of them taking place during in July-August 1996, according to USGS scientists.
