HILO, Hawaii – A swarm of earthquakes shook Hawaii's Big Island late Sunday evening, part of a pattern that has been ongoing since 2019. The U.S. Geological Survey reported a magnitude 4.3 ...
The most recent eruptions began after an increase in earthquake activity, according to the USGS. The Hawaiian Volcano Observatory detected the eruption through webcam images of the summit caldera ...
Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
Kilauea, one of the world's most active volcanoes, began erupting around 2:30 a.m. local time, according to the U.S. Geological Survey.
Near Kilauea volcano, the largest structure formed by the collapse of the southeastern flank of the island is the Hilina slump. This slump moves seaward at an average rate of 10 cm/year (3.9 in/year). The slump moved during the May 4 earthquake by about 0.6 m (2.0 ft) and has moved during previous earthquakes, such as those in 1868 and 1975. [16]
Along the Koa’e Fault Zone, there was a Mw 7.7 earthquake in 1975, and a Mw 7.2 earthquake in 2018. Though it is impossible to predict when large scale earthquakes will occur, researchers suggest that it could take another 25–30 years for enough stress to accumulate along the fault zone to cause another Mw >7 earthquake to occur.
The earthquakes occurred at depths between .6 and 1.9 miles below the ground surface, the USGS said. MORE: Kilauea, active Hawaiian volcano, could erupt like a 'stomp-rocket toy,' new study suggests
