Esattamente un anno fa nelle Regno di #Tonga si stava verificando la più violenta eruzione vulcanica mai avvenuta sul nostro pianeta dal 1883. Da allora sono stati effettuati centinaia di studi che hanno in parte rivoluzionato l'intera vulcanologia. Ecco un (lungo) riassunto! 🧵
𝟭. 𝗖𝗼𝗹𝗼𝗻𝗻𝗮 𝗘𝗿𝘂𝘁𝘁𝗶𝘃𝗮 La colonna eruttiva che si è formata durante la fase di massima esplosività ha raggiunto i 58 km di altitudine, la più alta mai raggiunta da quando esistono le rilevazioni satellitari.
Ciò vuol dire che i gas e le particelle espulse dal vulcano hanno raggiunto la mesosfera, ovvero il terzo dei cinque strati in cui è suddivisa l'atmosfera terrestre (troposfera, stratosfera, mesosfera, termosfera e esosfera).
This Sunday, January 15, will mark one year since the eruption of the Hunga Tonga–Hunga Haʻapai volcano shocked the world. I remember being awestruck by these images.
A short thread.
A short thread.
In the Volcanic Explosivity Index scale, the eruption was rated at least a VEI-5. It was the most powerful eruption since the 1883 eruption of Krakatoa with an estimated eq. TNT yield of 100-200 megatons, more than the Tsar Bomba, the most powerful nuclear weapon ever detonated.
Tonga volcano had the highest plume ever recorded. The column of ash reached almost 58km altitude (36 miles). After one hour, the cloud of volcanic ash was roughly 650km wide. For comparison, that's roughly size of mainland Spain. earthobservatory.nasa.gov/images/149474/…
El volcán #Tonga de enero de 2022 inyectó decenas de toneladas de vapor de agua (gas que más contribuye al efecto invernadero natural) en capas inusualmente altas de la atmósfera.
Pero para evitar manipulaciones, veo necesario aportar un poco más de contexto 👇

De 1750 a 2019, el forzamiento radiativo del H₂O ha sido entre 0 y 0,1 W/m² (90% de prob.). Solo el del CO₂ humano ha sido entre 1,9 y 2,4 W/m².
Es decir, del incremento de 1,3ºC que llevamos, el vapor de agua habría contribuido entre 0 y 0,06ºC.

Por otro lado: las modelizaciones preliminares sugieren un forzamiento radiativo en la tropopausa de +0,15 W/m² por ese aumento de H₂O.
El aumento del forzamiento debido al crecimiento del CO₂ antropogénico entre 1996 y 2005 fue de unos +0,26 W/m²

A mapping effort led by @NASAGoddard's chief scientist shows how the explosive volcanic eruption at #Tonga's #HungaTongaHungaHaapai obliterated the island. go.nasa.gov/3rE8jo4
“This is a preliminary estimate, but we think the amount of energy released by the eruption was equivalent to somewhere between 4 to 18 megatons of TNT,” said Jim Garvin. 🌋
For comparison, scientists estimate Mount St. Helens exploded in 1980 with 24 megatons and Krakatoa burst in 1883 with 200 megatons of energy. go.nasa.gov/3tRKk7t
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
#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

Por un oleaje en la zona de carga y descarga inusual propio de marea o algún evento fortuito natural como el ocurrido tras erupción de volcán en #Tonga y género #Tsunami u #OleajeAnomalo
En este caso si puede ocurrir un derrame por que genera que mangas tuvieran accidente.

We have friends from #Tonga. Here's 5 things they've told us re. the #TongaVolcanoEruption and #tongatsunami:
1. At least one inhabited island is now completely submerged. Survivors unlikely.
2. The main island is dependent on rain water for drinking... /1

It's now tainted by ash; no longer drinkable.
3. So, no water, AND it's the hottest time of the year. The people of Tonga now face the real threat of dehydration & disease. AND the hottest time of year brings w/ it the risk of cyclones. /2

4. All amenities are down (electricity, gas, telephones, etc). They are in the dark.
5. The ash cloud is so thick that Aust/NZ military could not land with aid. They had to turn back. Tonga is cut off for some time. /3

I think the #Tonga situation is the first disaster/humanitarian crisis in a while that has captured widespread attention on Aus/NZ Twitter (rightly so but I can list a lot y'all ignored). But some of the takes on what should be happening right now are... interesting. 🧵
Can definitely understand cynicism on Australia's response given we are facing a domestic crisis of inaction on COVID-19 +other issues. But humanitarians are doing the things. $1 million is fine as an initial commitment. Once more is known, that number will increase.
Also, you don't just show up with heaps of stuff or personnel and throw massive amounts of money at something like this without working closely with the national govt of the affected country. $1m is for initial humanitarian need. Then, there will be more once needs are assessed.
Mango Island #Tonga via Airbus SPOT imagery 1/16/22. Unfortunately the inhabited part of the island obscured by clouds. It appears either survivors or debris in a spot not normally occupied by people on lower right.
Reference image from 1/14/22 of Mango Island, you'll notice the bright spot visible in the other imaging not present. I suspect survivors of the tsunami put up some kind of shelter up at the high point of the island. Tent, leanto or stretcher. Looks like at least 5-6 people too
Tough to tell 100% but I would put money on these being people around a tent or some kind of temporary structure. #MangoIsland #Tonga #tsunami
Thick black clouds of ash, lightning, and toxic gases choked the skies as the underwater #HungaTonga volcano violently erupted over the weekend… the largest recorded eruption in over 30 years.

The blast triggered a tsunami and sent a visible shock wave around the world.
The plume of toxic gas and ash shot 12 miles into the air with a 161+ mile radius, according to @NOAA.

感谢 @a16z1215 的提醒，目前 #Tonga （汤加）火山的喷发事件所带来的影响很有可能会对局势带来一些改变，我们都知道这次的双顶上涨得益于放水和 #BTC ETF的通过，现阶段，美国对于疫情已经是开放状态，经济和就业都在回升也是美联储要执行加息和缩债的原因，但是汤加的火山爆发即便是美国都受到了影响
本次火山爆发的级别相当于5-6级（满级是8级），所造成的影响很可能会对农作物造成很大的冲击，上一次1815年4月的印尼火山爆发（预估仅2级）就导致了第二年北半球出现了严重的灾害，受灾包括了欧洲，北美和亚洲，大量的农作物死亡，天气变得极寒，人口大量减少。而此次的爆发势必也会造成局势的不安。
最大可能性就是全球出现粮食短缺的情况，而这种情况下对于生活用品的抢购很有可能会突破疫情时的情况，当然现在科技的发展远不是200年前可以比的，但是空气和气候的控制现在和200年前并没有本质的区别，即便不会发生大规模的群体事件，势必也会出现不稳定的情况，黄金将会成为投资的首选。
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.

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)
Postdisaster msg from HRH Princess Latufuipeka (daughter of King Tupou VI & #Tonga’s High Comm to 🇦🇺). Focus on gratitude, faith &taking refuge in God. This type of reaction overwhelmingly present on Tongan social media atm. Not what you’d usually get elsewhere,but consider (1/4)
#Tonga is one of the most vulnerable countries in the entire world to natural #disasters & climate change. In less than 4yrs it has weathered 2 max strength (Category 5) cyclones, a pandemic and a 1 in 1000yr volcanic eruption + resultant earthquake & #tsunami. (2/4)
And each time, people pick up & carry on. Often with humour & while singing a hymn! I’m no expert but I would think being grateful/positive, having a form of faith & relying on each other as a community helps ease the otherwise depressing mental effects of so much trauma. (3/4)
#Nomuka #Tonga via Sentinel-1 #satellite, before and after the #HungaTongaHungaHaapai volcano eruption.
This island south of Nomuka looks to have been inundated, based on Sentinel-1 radar image (darker areas = water).
Using a new feature of @sentinel_hub here's a sequence of SAR radar before/Sentinel-2 true color before/and then SAR radar after where you can see where the reflectivity of the land has changed to water.
