So, all these images that follow were made by 'Paradise Helicoper' showing the amazing landscape of the Mauna Loa eruption, as well in several photos you can see the twin volcano Mauna Kea. Now Mauna Kea may night look so mighty - because the area of the Saddle (road) is already 2000 meter high, so Mauna Kea only sticks out with 2100 meter.

Geochemical analyses are starting to come back from samples collected from the Mauna Loa lava flow!
Erupted lavas have undergone a rapid analysis by HVO and our partners at the University of Hawai'i Hilo. Lavas from the first 48 hours of the eruption are all very similar—samples from close to the eruptive vents are glassy and have no or very few minerals, whereas lavas sampled at flow fronts far from the eruptive vent have small crystals (<0.01 mm or 0.0004 inches) of plagioclase and olivine that grew during cooling of the lava flows. These samples have an MgO (magnesium oxide) content of 6.0-6.8 weight percent, which is very typical of Mauna Loa magmas. The average eruption temperature calculated from these MgO contents is 1156 degrees Celsius (2113 degrees Fahrenheit).
Preliminary comparison of new lava chemistry with other historical Mauna Loa eruptions shows that the new lavas are not leftover from the 1984 eruption, but instead represent a new intrusion of magma into the summit and northeast rift zone, consistent with geophysical signals. Field crews report that today's lava flows remain crystal free near the vents and full of small crystals at the flow fronts. Continued chemical analyses in the lab will help us understand how the eruption is evolving.

Campi Flegrei, Pozzuoli, Napoli - Italy
I list the earthquake activity here instead under the earthquake thread, since the partially submerged Campi Flegrei Caldera is volcanic. There has been a lot of seismic activity in the area - and German Vulkane.net wrote following:
Vulkan Campi Flegrei mit neuen Erdbeben am 30.11.22 - Vulkane Net Newsblog
Unter dem Claderavulkan Campi Flegrei bebte die Erde. Der stärkste Erdstoß hatte eine Magnitude von 2,6 und ein Hypozentrum in 2 km Tiefe.
Earthquake M 2.6 at Solfatara
Date: 30 Nov 2022 | Time: 02:34:39 UTC | 40.8313 ; 14.1488 | Depth: 2 km | Mb 2.6
Last night there were again some earthquakes under the Italian Caldera volcano Campi Flegrei. The strongest earthquake had a magnitude of 2.6 and a hypocentre at a depth of 2 km. The epicentre was on the north-eastern rim of the Solfatara crater near the Pisciarelli fumarole. Two other earthquakes had magnitudes of 2.3 and 2.0. A total of 7 tremors were detected.
Yesterday, the new weekly bulletin also appeared at INGV. Last week, 30 weak earthquakes were registered. In the previous week, there were 195 tremors, as there had been a seismic swarm. The most remarkable thing, however, is that the ground uplift has increased significantly, which I had already suspected due to the swarm quake. The uplift rate increased to 15±3 mm per month. This is double the rate of the previous observation period. The value is considered preliminary, as further measurements seem necessary. At the RITE measuring station, a ground uplift of a good 95 cm has been observed since 2011. The gas temperature of the Pisciarelli fumarole rose from 87 to 93 degrees and is close to the condensation point.
The activity of the Campi Flegrei is related to the bradyseismos. For millennia, the coast in the Gulf of Pozzuoli has been rising and falling. In Roman times, the coasts rose and fell by a good 2.5 metres. The engine behind the Bradyseismos is most likely magma, which collects in a 5 km deep magma body and fuels the volcano's hydrothermal system.
The Campi Flegrei conceals the largest caldera volcano in Europe.
It has a diameter of 15 x 11 km. This even surpasses the Santorini caldera, which is 11 km in diameter. Both volcanoes erupted in historical times, with the Bronze Age eruption of Santorini (Thera) being more powerful than the last eruption of the Campi Flegrei in the 16th century. Looking further back, the tide turns: 39,000 years ago, the Italian caldera produced an eruption with a VEI 7-8. If such an eruption were to happen again today, Europe would have to deal with massive problems.

Etna - Sicily, Italy
At Etna, there has been some mild activity going on for while but nothing major and no Paroxysm. Nevertheless, a lava stream has appeared which Dario Lo Scavo captured beautifully.
Pico de Teide, Tenerife, Spain
Accidentally I stumbled across the notification about low magnitude seismic activity occurring right under the mighty Pico de Teide volcano.
Update on seismic activity in Tenerife: 17:00 hours (Canary Islands time) on 28 November 2022
From 03:11 hours (Canary Islands time) on Friday 25 November until 17:00 hours (Canary Islands time) today 28 November 2022, the Canary Islands Seismic Network, managed by the Volcanological Institute of the Canary Islands (INVOLCAN), has detected more than 100 low magnitude earthquakes. Of these events, it has been possible to locate 77. The hypocentres are located mainly in the area of Las Cañadas at depths of between 10 and 20 km. The maximum magnitude recorded was 1.3 (Richter scale). The last earthquake of this seismic series was recorded at 00:57 hours (Canary Islands time) on 28 November 2022.
Here a few impressions from Pico de Teide
within the vast caldera area (2100 m above the sea) at night. It was... magic. While there is a hotel within the caldera - but everybody is sleep - while I was out and about all night on 1 April 2014 at +3°C, strong winds and fascinating views, very dark sky and plenty of stars glittering. A storm front started approached the mountain with clouds. It really makes you feel like you are on a different, magical planet.
There is something special about the landscapes within large volcanic calderas; such as Bromo-Tengger on Java, Indonesia, Pico de Teide on Tenerife, Etna's Valle del Bove in Sicily, Monte Somma-Vesuvio in Italy, and similar. Especially when you compare the views between daylight vs night time. So much to see and take in... or I should rather say; "to sense and feel"

Sulfur dioxide from Mauna Loa volcano to reach Mexico
Sulfur dioxide (SO2) emanating from Mauna Loa, the world's largest active volcano, after its first eruption in almost 40 years, could reach Mexico as it travels through the atmosphere.
The Copernicus Atmospheric Monitoring Service (CAMS) forecast shows the evolution of this gas plume moving southeastward over the Pacific Ocean and into North America.
From satellite observations, it determined that SO2 has already reached western North America and estimates that it will cross the United States and Mexico into the Atlantic Ocean and the Caribbean before dissipating.
The service forecast shows the displacement of the gas. It shows how the sulfur dioxide will move over Mexican territory during the first days of December.
SO2 will transit through areas such as the Baja California peninsula and states such as Sonora, Sinaloa, Durango, Chihuahua and Coahuila and then cross over the United States.
However, after their analysis they concluded that this is unlikely to have an impact on the country's air quality.
"The impacts of SO2 released from Mauna Loa on climate and surface air quality are likely to be very small," said Mark Parrington, CAMS senior scientist.
"Most of the SO 2 emitted is found higher in the atmosphere above the surface, especially as you move away from the source, and can be visible as a light haze in the sky," he explained.

Yes, seismic activity also increased. Maybe it has to do with changes in the magnetic field. We have animals acting weird and now the airports will have to adapt to the changes in the magnetic field.
The Repositioning of Earth's Magnetic Field Requires Changes to the Runways at Reno's Airport​
The magnetic field of the Earth moved magnetic north. It's always in motion. Magnetic north has shifted enough over the years that manual compasses must be recalibrated, printed maps may be out of current, and airport runways may be renamed.
"The earth changes, and as that molten core shifts, you can shift a little bit for pilot safety, because it's always all about safety," explained Brian Kulpin of the Reno-Tahoe Airport Authority.
Runway 1634 right has been renumbered 1735 right. The runway number 16 was repainted to 16 R a few weeks ago.
The numerals not only identify runways, but they also indicate pilots how far the runway is from magnetic north.
According to pilot Jonathan Hartness, electronic cockpits are automatically updated.
"It's a really simple change, nearly seamless for those with glass cockpits and a lot of avionics and electronics," he explained.
Airport runways are being replaced around the country. Hartness stated that he witnessed Florida renovate their runways a few weeks ago.
Reno's airport serves 4.3 million passengers each year. From the airport, pilots fly 150 flights every day.
"They're all using these runways, so you have to have the correct designation for safety," Kulpin explained. "It helps all those planes line up and be and be managed by the air traffic control tower."
Most people will be unaware of the changes, which are necessary to keep people safe.

You may be onto something with this.
It occurs to me that these animals are spinning, it is because they try to "adapt" to the change in the electromagnetic field.
When turning they seek to "acclimate" to it.
