KILAUEA VOLCANO, BIG ISLAND (HawaiiNewsNow) - A 4.2-magnitude earthquake shook parts of the Big Island early Tuesday, but there's no tsunami threat to the state, the Pacific Tsunami Warning Center said.
The earthquake struck about 12 miles southeast of Volcano around 2:45 a.m., according to the U.S. Geological Survey.
There were no reports of any injuries or damage.
Hawaiian Volcano Observatory officials say they have noticed an increase in earthquakes at Kilauea's east rift zone since 2 p.m. Monday.
There's also been an increase in lava activity over the last few days, with the lava lake overflowing several times, even spilling onto the floor of the Halemaumau Crater.
Officials say they're continuing to monitor the situation and plan to observe the area by helicopter on Tuesday morning if weather permits.
