"i checked last night and there were only 2 earthquakes at around 3.3 but to see so many in the last few hours is scary and unbelievable. i got this horrible feeling that the ring of fire will go up in one big bang! i went to yellowstone a few years ago and took few measurements of its growth, there was clear sign that there is a build up of pressure, i hope the constant earthquakes dont weaken the cap!"

Big Island’s Mauna Loa began erupting Sunday evening following earthquake

November 28, 2022 · 10:51 AM GMT

An eruption began about 11:30 p.m. Sunday in Moku‘āweoweo, the summit caldera of Mauna Loa, inside Hawai‘i Volcanoes National Park on the Big Island.

The Hawaiian Volcano Observatory has issued a RED/WARNING.

At this time, lava flows are contained within the summit area and are not threatening downslope communities. Winds may carry volcanic gas and possibly fine ash and Pele’s hair downwind.

The eruption began about a half hour after a 4.4 magnitude earthquake occurred in the summit area of Mauna Loa. A 4.1 magnitude earthquake also occurred on the summit region of Mauna Loa at 11:52 p.m. Sunday, according to the National Weather Service in Honolulu.

Residents at risk from Mauna Loa lava flows should review preparedness and refer to Hawai‘i County Civil Defense information for further guidance.

The National Weather Service has issued an ashfall advisory until 6 a.m. Monday morning. Up to one-quarter inch of ashfall accumulation is forecast for a portion of the Big Island.

It could cause possible harm to crops and animals and reduce visibility. People with respiratory illnesses should remain indoors to avoid inhaling the ash particles and anyone outside should cover their mouth and nose with a mask or cloth

Mauna Loa was long overdue to erupt. The volcano had erupted 33 times since 1843, but the last time had been March 25, 1984.

Based on past events, the early stages of a Mauna Loa eruption can be very dynamic and the location and advance of lava flows can change rapidly.

If the eruption remains in Moku‘āweoweo (the summit caldera), lava flows will most likely be confined within the caldera walls. However, if the eruptive vents migrate outside its walls, lava flows may move rapidly downslope.

The Hawaiian Volcano Observatory is in close consultation with emergency management partners and will be monitoring the volcano closely to provide further updates on activity. As soon as possible, the observatory will conduct aerial reconnaissance to better describe the eruption and assess hazards.
