KAILUA-KONA, Hawaii (AP) — Waves of orange, glowing lava and smoky ash belched and sputtered Monday from the world’s largest active volcano in its first eruption in 38 years, and officials told people living on Hawaii’s Big Island to be ready in the event of a worst-case scenario. The eruption of Mauna Loa wasn’t immediately endangering towns, but the U.S. Geological Survey warned the roughly 200,000 people on the Big Island that an eruption “can be very dynamic, and the location and advance of lava flows can change rapidly.” Officials told residents to be ready to evacuate if lava flows start heading toward populated areas. |

not sure it's "doomsday"...as I posted, this volcano has been erupting like this for a very long time and humans have coexisted with it. There can always be a bit of property damage with these things, as with the last Kilauea eruption, can fissure from vents within populated areas, but --to me, that tells me that we humans have to learn to not build neighborhoods in areas that lie on historic rifts/vents as well (planning departments take note). It looks like in the past, eruptions have lasted no more than a few days or at the most, a couple weeks (see my link at previous post with eruption history), and often. This long pause of nearly 40 yrs seems to be an anomoly in the eruptive behavior. I do wonder if that will make a difference in the duration time of this eruption...but Pele does what Pele does! Kilauea seems to have much longer eruptive periods (giving lava more time to accumulate and flow). Of course, one never knows what's going to happen with a volcano. That's part of the fascination and myth. Pele's sometimes unpredictable and tempermental. Time to take some berries and whiskey up the mountain. |

I don't think shatterbrain is capable of posting without adding stuff like 'doomsday.' It's just a part of their nature.. you know.. get excited.. run around like the world's coming to an end.. the sky is falling.. The folks here, the Hawaiian community, is jazzed the eruption started on their Independence Day.. sort of a chicken skin kine moment.. which will hopefully help them feel more empowered to further their renaissance.. but in the big picture.. no the sky ain't falling. |

Moku'āweoweo Caldera is seen Monday via webcam from the US Geological Survey. ******** The world’s largest active volcano, Mauna Loa, is erupting for the first time in nearly 40 years, sparking an ashfall advisory Monday for Hawaii’s Big Island and surrounding waters until 10 a.m. HT (3 p.m. ET). The eruption in Hawaii Volcanoes National Park is not threatening downhill communities or flights to the Island of Hawaii, the Hawaii Tourism Authority tweeted Monday morning. Still, a “trace to less than one quarter inch” of ashfall could accumulate on parts of the island, the National Weather Service in Honolulu said, as winds may carry fine ash and volcanic gas downwind. “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,” the Honolulu office warned. “Possible harm to crops and animals. Minor equipment and infrastructure damage. Reduced visibility. Widespread clean-up may be necessary.” Ashfall can damage vehicles and buildings, contaminate water supplies, disrupt sewage and electrical systems, and damage or kill vegetation, the weather service says, while abrasive volcanic ash can irritate eyes and lungs. Lava flows are contained in the summit area and do not threaten downslope communities, the Hawaiian Volcano Observatory said. “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,” the observatory said, adding, “If the eruption remains in Moku’āweoweo, 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.” Red hues from the eruption illuminated Monday’s predawn sky, according to footage captured at the Kailua Bay & Pier by Matthew Liano, a resident of Kailua-Kona, along the Big Island’s west coast. “The glow is like nothing I’ve seen here living in Kona for most of my life,” Liano told CNN. The eruption began in Moku’āweoweo, the summit caldera of Mauna Loa, on Sunday around 11:30 p.m. HST (4:30 a.m. ET Monday), according to the observatory. Volcano is near Kilauea, which erupted in 2018 Mauna Loa, which covers half the island of Hawaii, has erupted 33 times since 1843, the volcano’s first “well- documented historical eruption,” according to the US Geological Survey. It last erupted in 1984, making this prolonged quiet period the volcano’s longest in recorded history. Mauna Loa’s summit crater sits about 21 miles west of Kilauea, a smaller volcano whose eruption over months in 2018 spewed lava into the Leilani Estates neighborhood, destroying more than 700 homes and displacing residents. Mauna Loa has been in a heightened state of unrest, per the agency, which pointed in an update late last month to elevated seismic activity and increased earthquake rates. Earthquake activity increased from five to 10 earthquakes a day since June 2022 to some 10 to 20 earthquakes a day in July and August, according to the US Geological Survey. Peak numbers of more than 100 earthquakes a day were recorded on September 23 and September 29, CNN has reported. The increased activity prompted Hawaii Volcanoes National Park in October to close the Mauna Loa summit to all backcountry hikers until further notice, though the US National Park Service said the main section of the park has remained open. |

The eruption, which, true to form started at the summit in the middle of the night without any forewarning, has moved outside of the caldera, and is currently centered to the Northeast of the summit. The best (only?) camera station view is from the upper flank of Mauna Kea, here and posted here..  That shot is within the last few minutes.. ie it's an active link, will change over time.. And here is a view from Waiakaloa at 6:15 this morning of the same area..  And the latest updates are being posted by the HVO on Twitter here.. https://twitter.com/USGSVolcanoes So far, at a first glance, the seismicity is pretty tame.. more soon.. |

USGS Volcanoes Lava flows on Mauna Loa moving in 'best possible direction,' mayor says Nov. 28, 3:33 p.m. Mitch Roth, the mayor of Hawaii County, said Monday that the lava flows on Mauna Loa were flowing in a direction that is not threatening to communities near the volcano. Pahala, Naalehu, Ocean View, Milolii, Napoopoo, Captain Cook, Kealakekua and Keauhou — areas in the southwestern rift zone that are at high risk in the event of a major eruption — were not threatened as of Monday afternoon, Roth said in a news release issued at noon local time.

Aerial view of Mauna Loa on Hawaii Island erupting from vents on the northeast rift zone. Flows are moving downslope to the north on Nov. 28, 2022. USGS Volcanoes “Our team is on full alert and is prepared to respond to whatever situation may arise as a result of the Mauna Loa eruption,” Roth said. “That said, we’ve been told that the lava is heading in the best possible direction, which is away from our communities. We’ll continue to monitor the situation and will be providing updates to the community regularly. Until then, we thank our State and County partners, departments, and agencies for their quick action and attention to every detail.” The release from the mayor's office said that while scientists are monitoring the eruption that began Sunday, it remains unknown how long the event will last and how much lava will flow from the volcano. No evacuations were in place as of Monday afternoon. Shelters were opened in Kau at the Robert Herkes Gymnasium and the Old Airport Gym in Kailua-Kona, due to people self-evacuating out of caution, the mayor's office said. No road closures are in place except the Mauna Loa Access Road, which was shut down to traffic early this morning. Officials release map with vog forecast amid Mauna Loa eruption Nov. 28, 2:23 p.m. Officials released a forecast model Monday showing the dispersion of volcanic emissions, also known as vog, on the Big Island of Hawaii and their impacts on air quality levels amid Mauna Loa's eruption. The forecast said there were moderate levels of emissions — sulfur dioxide and sulfate aerosols — on Monday. The VMAP Vog Forecast Dashboard is intended to identify areas of possible health risks for the general public under standards set by the Environmental Protection Agency, the U.S. Geological Survey, which is monitoring the eruption, said on Twitter. The USGS reiterated on Monday afternoon that lava flows are not threatening downslope communities amid the eruption. Get the latest information on the eruption from the USGS website. Southwest cancels some Hawaii flights as Mauna Loa eruption spews ash Nov. 28, 1 p.m. Southwest Airlines has suspended operations at Hilo International Airport due to Mauna Loa on the Big Island of Hawaii erupting late Sunday. The temporary suspension resulted in the cancellation of 10 interisland departures. Southwest operates five round-trip flights a day between Hilo International Airport and Daniel K. Inouye International Airport in Honolulu. Get more details on how travel in Hawaii is being impacted by the volcano at SFGATE. Officials release images of lava flows at Hawaii's Mauna Loa Nov. 28, 11:15 a.m. Officials released images on Monday of the lava flows on Mauna Loa, a volcano on the Big Island of Hawaii. The world's most active volcano started erupting for the first time in nearly four decades on Sunday night. The images show the volcano erupting from vents on the northeast rift zone. "Flows are moving downslope to the north," the U.S. Geological Society said. As of 11:02 a.m., the USGS said lava flows were not threatening downslope communities. The agency said crews were on-site this morning collecting information to create lava flow forecasts to identify potential hazards. The National Weather Service announced at 11 a.m. that an ash advisory had been canceled but warned that people with respiratory illness should be aware of "the potential for areas of low air quality due to vog," which occurs when volcano emissions are mixed with fog. #MaunaLoa is erupting from vents on the Northeast Rift zone.

AP Hawaii issues travel advisory for two airports on Big Island as Mauna Loa erupts Nov. 28, 10:40 a.m. The Hawaii Department of Transportation issued a travel advisory on Monday morning for two airports on the Big Island, where the Mauna Loa volcano is erupting. "Passengers with flights to Hilo International Airport (ITO) or the Ellison Onizuka Kona International Airport at Keahole (KOA) should check with their airline prior to heading to the airport due to the volcanic activity at Mauna Loa," the department said via Twitter. Lava flows from Hawaii's Mauna Loa are not threatening communities Nov. 28, 10:25 a.m. The eruption of Hawaii's Mauna Loa volcano shifted from the summit caldera to the northeast rift zone, with fissures feeding several lava flows, the U.S. Geological Survey said at 7:20 a.m. local time. "Lava flows are not threatening any downslope communities and all indications are that the eruption will remain in the Northeast Rift Zone," the USGS said in its update. "Volcanic gas and possibly fine ash and Pele's Hair may be carried downwind." Hawaii's Mauna Loa erupts for first time in nearly four decades Nov. 28, 6:38 a.m. Mauna Loa on the Big Island of Hawaii erupted for the first time since 1984 on Sunday night, spewing a massive cloud of ash and debris. The volcano's lava flow is contained within the summit and as of Monday morning there continued to be no threat to nearby communities, the U.S. Geological Survey said. Mauna Loa is the world's most active volcano and has erupted 33 times since 1843, the first time an eruption was documented, according to the USGS. In 1984, lava flows were within 4.5 miles of Hilo, the largest community on the Big Island with a population of 44,000 people.

Mauna Loa's summit, cabins and high-elevation areas have been closed due to increased seismicity since Oct. 5. Sunday's eruption was first reported at 11:30 p.m. local time within Mokuaweoweo, the summit caldera of the volcano that's within Hawaii Volcanoes National Park. The USGS advised residents in the area of the volcano to review eruption preparations. "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," the USGS said. How long the volcano erupts and whether it could cause lava to flow to populated areas of the island is impossible to predict, said Miel Corbett, a USGS spokesperson. “But I can tell you, we’re in constant communication right now with Hawaii Civil Defense, and they’re providing updates to community members,” she said. |

Subject: Re: Mauna Loa - thoughts.. 7pm local
The eruption has changed considerable when compared to the pics going 'round. Earlier this afternoon HVO released this map of the vents.. And then later, posted an update at https://www.usgs.gov/volcanoes/mauna-loa/volcano-updates Which in part reads.. The eruption of Mauna Loa continues on the Northeast Rift Zone. Three fissures erupted and as of 1:30 PM, only the lowest of the three fissures was active. Which is sorta what I hinted at in my last post.. and makes those two dramatic flows that have gone round and round all day over.. and the third fissure, which at first was the smallest.. now getting all the lava that is erupting. The thing about that fissure’s location is it straddles the ridge of the rift and as such which way lava flows from there will go, to the northeast towards Hilo (which HVO is hinting at being their assumption), or the southeast towards parts of the town of Volcano and Puna, or, as it is at least as likely to do given the history of eruptions on that end of the volcano, the vent itself could further migrate in the next day or two.. time will tell. |

Based on the one real time photo station's view, at this time just after 11:30am local time.. Note that the above pic is being generated in close to real time and the weather between camera and the volcano can block the view. It was clear at the top of the 11am hour (local).. Along with the seismicity as seen here.. https://www.usgs.gov/volcanoes/mauna-loa I suspect the eruption has been migrating, as is its historical behavior during the onset of an eruption, further to the east. If this holds true, it will send all the flows generated down a path that will lead.. over weeks.. towards Hilo. |
