No tsunami advisories were issued after a 4.0 magnitude earthquake under Hawaiʻi Island early Monday morning.
The earthquake struck about 5 miles east-northeast of Pāhala at a depth of 20 miles around 1:55 a.m., The U.S. Geological Survey said.
“This earthquake appears to be part of the seismic swarm under the Pāhala area, which has been going on for over a year. Out of over 10,000 earthquakes that were detected in the area over the past year, four have been magnitude-4 or greater,” Hawaiian Volcano Observatory seismologist Jefferson Chang said.
The earthquake had no apparent effect on nearby volcanoes. HVO continues to monitor any changes.
