🌋 A recent study by @Olenellus & @GambixPT published in @geosociety found that “an extinct #volcano off the shore of Portugal could store as much as 1.2-8.6 gigatons of CO2, the equivalent of 24-125yrs of the country’s industrial emissions.”

🧵1/9 Image
“Doing so would rely on a method known as in situ mineral #carbonization, which works when the CO2 taken from the air is pumped deep underground.”
“Once in the bowels of this extinct volcano, calcium, magnesium, and iron react to the incoming carbon dioxide to form calcite, dolomite, and magnesite, trapping the CO2 forever in a rocky prison.”

What is #BatikAir flight 7583 doing? It's trying to land at #Malang airport, but there is an ash NOTAM.

#volcano #eruption #EastJava #Indonesia Image
It has made one go-around and is returning to the airport for a second chance I think.
It just flew over the airport at 13.000 feet. Weird.

Amazing footage from Paradise Helicopters of Mauna Loa volcano on the Big Island erupting.

More amazing videos of Mauna Loa’s eruption in #Hawaii. Lava is about 3 miles from the major highway that connects Hilo and Kona. Officials say they’re equipped to shut down roads as early as Friday if lava crosses l l the road.

S1.E6 Breakdown of #TheRingsOfPower 🧵

This episode was very explosive. Not much #Tolkien to breakdown but very fun all the same.

Theory: This is Sauron's gauntlet. Adar claimed it as a trophy.

#TheOneRingQuisition Image

Adar plants some alfirin seeds and says a prayer before battle.

Quenya: `Vinya coivië... na vírië...`
English: "New awakening... To life..."
1. `My children, we have endured much...`

Adar's plans laid bare:

S1.E4— `That [the Southlanders] may live if [they] forsake all claim to these lands and swear fealty to him.`

S1.E5— `And soon [the sun] will be gone. And with it, the part of me that knew its warmth as well.` Image

The eruption is over but the ground is still shaking - there have been dozens of #earthquakes around the #HungaTonga #volcano (magnitude 4.5-5), continuing today. 1/3

#GoogleEarth #Tonga #earthquake
Many are likely due to slip on existing faults or fracturing of new ones due to changes in crustal stress caused by the eruption. Others may be linked to magma movement, although that usually produces a more persistent signal called #volcanictremor. 2/3…
I haven't seen any focal mechanisms for these events, which would tell us more about the type of #earthquake - it may be difficult to extract that information as these events are M5 or less, and seismic networks are sparse in this region. 3/3

Kanokupolu #Tonga taken yesterday, 1/16/22 via Airbus SPOT #satellite. Post volcano/tsunami. High resolution image, this looks to me to be ashfall.
#Tonga taken by Airbus SPOT on 1/16/22. This is (was?) Ha'atafu Beach and Haatafu Beach Resort, but it seems to me that there are structures missing on this side (the resort appears to me to be missing, or extremely covered with ash). Possible tsunami scouring on the beach.
Reference image in Google vs. this acquisition -- you can see the big building on the top right in both images, but none of the structures you'd expect at Ha'atafu Beach, Nuku'alofa itself. #tonga #tsunami #volcano

Tonga Navy appears to have just reached the island of #Nomuka
This ship (the only one transmitting satellite AIS data) came from Nuku'afola this morning, when officials said they would be sending the Tonga Navy to the outer islands.
Found this video I had missed earlier from this location (FB Live... shot just as the seas were retreating. Hope this person made it up a hill, what was coming as likely worse)

Hunga-Tonga-Hunga-Ha'apai #volcano before/after the eruption. Sentinel-1 satellite (-20.48838, -175.28037)
Hunga-Tonga-Hunga-Ha'apai #volcano on the left, you can see the interference patterns on the waves from the tsunami impacts (another volcano on the right). The gob of stuff in the middle was not there before, maybe floating tephra or something else radar reflective.
No tracking details on these ships (premium satellite data) but there are a few fishing boats that got one heck of a wakeup call earlier. There's a few that were VERY close to the volcano. (60 miles away on open ocean).

A #volcano just erupted near #Tonga - but why was it there in the first place?

Tonga sits on top of the #TongaKermadec #subductionzone, where the #PacificPlate sinks below the #AustralianPlate.

The subducting #PacificPlate carries the culprit into the mantle: #water. 🧵1/3 Source: https://source.wust...
Some people think that volcanoes at subduction zones are due to frictional heating from the two plates rubbing against each other - NO!

In this case, melting is because of the addition of water, sort of like how adding salt can make ice melt. 2/3

Is this the only volcano in the region? Absolutely not. Volcanoes parallel the plate boundary, a string of conical mountains 2000 m high, occasionally poking above the sea. Usually quiet, but built over millions of years through thousands of eruptions. 3/3

A major volcanic eruption resulted in a #tsunami offshore #Tonga, reports from there are scarce, but I tried to estimate the tsunami pattern due to the potential dome collapse of Hunga Tonga-Hunga Haʻapai #volcano
The simulation estimates the tsunami triggering via a sliding mass of up to 2 km³ volume. It might be an overestimation, but data is still coming in.
First eye witness reports/videos from Tonga already indicate major inundation for #Tonga Image
We have reports of waves +/- 0.5 - 1.5m from Samoa, Fiji, New Caledonia, Norfolk Island, even Australia and many more places.

Currently working on a simulation for the farfield effects. But calculation takes a while.

Incredible satellite footage of the volcanic eruption in #Tonga ..

#Tsunami alert going on currently as well and footage showing it’s already started hitting some islands.. crazy🤯

Mother Nature is undefeated 🌊💨
Praying for everyone being affected by this..

Cannot imagine seeing this with my own eyes.

*not my footage*

If this were true, don't u think it would be a much bigger story? 🤔
Still, worth a share... Just in case.

EAST COAST PAY ATTENTION #VOLCANO 🌋🌋🌋🌋Locals on LaPalma have uploaded a photograph which they say shows "Detachment."   Part of the land which is FEARED to slide into
the Atlantic Ocean and cause a Tsunami to the east coast of the United States, appears to have begun to DETACH at its top. There is a very clear tear in the forest atop the mountain showing bare earth along the uppermost ridge there the trees on the land have torn away from each
other.  If this photo shows what the locals claim, then the landslide could happen today 
Those on the U.S. east coast must pay extra close attention to this today.  Events are taking place at a greatly increased speed.

An #eruption of #Nyiragongo #volcano (#DRC) began in the evening of May 22. #Meteosat satellite data (from @CIRA_CSU) show a strong thermal anomaly appearing at 17:15 UTC, and a small #volcanic plume amidst widespread regional convection. Follow @CharlesBalagizi for updates.
If you're looking for background info on #Nyiragongo and its previous flank #eruptions in 1977 and 2002, there's a collection of papers in the Italian Acta Vulcanologica journal available here (with free PDFs):…
#Sentinel5P #Tropomi data on May 23 show SO₂ emissions from the #Nyiragongo #eruption. SO₂ to the SE over #Tanzania is at higher altitude (perhaps to tropopause level) and was emitted during the initial, more energetic phase of the eruption (17:00 UTC, May 22). @VirungaSupersit Image

2. On January 20, 2021 at 14:27 WIB, a hot cloud of avalanches was recorded on the seismogram with an amplitude of 30 mm and a duration of 117 seconds. Awanpanas rolled into Boyong River with a sliding distance of 1500 m. The wind blows north.

Protect yourself from ash. As the eruption continues at #lasoufriere, SVG we share this information taken from the The International Volcanic Health Hazard Network #IVHHN on ash and its associated hazard. #volcano #stilldangerous #svg #uwiseismic ImageImage
Volcan ash fall will be a pervasive hazard throughout St Vincent and is expected to reach neighbouring islands such as Barbados. Volcanic ash is not necessarily deadly but can lead to respiratory problems and may also impact vehicles and plane engines. #volcano #stilldangerous

Another explosion observed. The vertical ash column estimated to have gone approximately 4km into the atmosphere. We continue to monitor and update. #lasoufrière #volcano #svg #redalert #stilldangerous ImageImage
Photos of the 2nd plume from the Observatory and from a camera at one of our seismic stations on the flanks of the volcano. #LaSoufriere #svg #uwi #redalert ImageImage
Occurred at 2:45 pm local time. Plume was clearly seen from the capital.
