A magnitude 5.0 earthquake struck the world’s largest active volcano. Scientists said there was a “state of heightened anxiety”.

Mauna Loa volcano, which covers half of Hawaii, experienced a series of tremors, with a magnitude 4.6 tremor recorded just seconds before the larger one.

The aftershocks, which can still be felt, could last for weeks, with scientists closely monitoring the increased activity.

The Hawaiian Volacano Observatory said, “The tremors from the larger earthquakes may have been strong enough to cause minor localized damage, particularly to older buildings.

“The two earthquakes occurred within 24 seconds of each other and caused shaking of longer duration and potentially greater intensity than either earthquake alone would have caused.”

According to the US Geological Survey, earthquake activity in the region has increased from five to 10 earthquakes per day since June 2022 to 40 to 50 earthquakes per day in the last two weeks.

Highs of more than 100 earthquakes per day were recorded on September 23rd and 29th.

The increased seismic activity prompted Hawaii Volcanoes National Park to close the Mauna Loa summit hinterland until further notice.

Hawaii County Mayor Mitch Roth said there were no immediate reports of major damage or injuries, but there was some minor damage in the town of Pahala.

Mizuno Superette, the only store in rural Pahala, closed about an hour and a half after the shaking left broken glasses on the floor and the power went out, cashier Laurie Tackett said.

She said: “The ground was just shaking, it was a bit scary.”

They confirmed that Mauna Loa is not erupting and there are no signs of an impending eruption.

The observatory added, “This sequence of earthquakes appears to be related to adjustments along the southeast flank of Mauna Loa volcano.

“On several occasions, large earthquakes have preceded Mauna Loa’s eruptions, although these were usually larger than today’s earthquakes.

“It is currently unknown whether this earthquake sequence is directly related to the ongoing unrest on Mauna Loa.”
