インドネシアの火山島、津波で東京ドーム200杯分が崩落 - 毎日新聞 mainichi.jp/articles/20190… 「山体崩壊で崩落した土砂が0.21~0.26立方キロに上るとの解析結果を、東京大地震研究所の前野深准教授がまとめた」 …見出しが変だけど。

These maps (from Thornton and Rosengren, 1988) show #AnakKrakatau the last time it hosted a crater lake, in 1931-52. The crater lake was filled in by lava flows and tephra in 1960-63. royalsocietypublishing.org/doi/pdf/10.109… pic.twitter.com/1Bv5ludtFz

Digging through some “before” photos of island of Rakata near Anak #Krakatau shot in August 2018 and comparing to now. The beautiful jungle beach wiped away by the tsunami #volcano #Indonesia pic.twitter.com/eWHHe3ljh8

#AnakKrakatau volcano today 13th January as seen from hellicopter. Indonesian authorities say the amount of eruptions have recently declined, but the restriction/danger zone is still at 5km. Video by: BNPB - Indonesian National Disaster Mitigation Agency. twitter.com/Sutopo_PN/stat…

High res 4K drone footage of Anak #Krakatau #volcano after the devastating collapse, major eruption and #tsunami - you can clearly see the new, shallow crater lake, intense colours in the sea water and major devastation to nearby islands from the tsunami youtube.com/watch?v=I-3A4G…

Another successful and safe day filming at #Krakatau - the #volcano was quiet. Today I took the drone higher to catch not only the island but also the amazing color of the sea water #Indonesia pic.twitter.com/m3E4APgiDy

Clear satelite image of #Krakatau volcano captured 10th January by #Sentinel2. There is still a lot of discoloration in the sea next to Anak-krakatau (middle). A white plume is also seen rising from the island. pic.twitter.com/dEw5lHq99z

There appears to be a distinct sea water “crater lake” now with lots of steam and gas emissions on its edge nearest the ocean #Krakatau pic.twitter.com/NxEryofVXi

Here we’re approaching collapsed part of #Krakatau - I can see sea eating away at pancake shaped volcanic deposits (fresh I believe.) Freshly erupted material from “undersea” eruptions usually susceptible to erosion from waves. Also note large crack, looks to be water channel? pic.twitter.com/UvpIrGQReM

Moving on to Kecil island to east of #Krakatau - the entire island’s vegetation was been decimated. I’m assuming this is because it was downwind of the most intense activity and copped huge amounts of ash, toxic gases and acid rain. Should be noted veg on Rakata totally unharmed pic.twitter.com/tr2NFMussL

Out all day filming at #Krakatau - didn’t witness any explosive eruption but to see and shoot the vast changes at the volcano is mind blowing. Many images to come but here’s a teaser (shot outside 5km danger zone.) #volcano #Indonesia pic.twitter.com/n1SHcuXqIp

Suggests that magma might have been close to the surface on the flank of the cone. Consistent w/ testimony of fishermen near #AnakKrakatau on Dec 22 (posted by @OysteinLAnderse) who reported a flank/lateral #eruption before the collapse and tsunami. @vulkanologi_mbg

Possibly significant @planetlabs obs of pre-collapse #AnakKrakatau from Sept-Oct 2018.

あそこはヤバすぎる。両岸の村落には新しい移住地を用意して、海洋警察と海軍以外の常駐は認めない方がいいんじゃないかな?

22:30 UTC 観測のSentinel-1 画像を見ると、山頂は崩れつつもまだ海面上に見えていて、西側は海没している。南側はよく見えないけどまだ残ってるように見える。 https://twitter.com/flyingwktk/status/1076822530768424960

原発のことでとんでもない醜態を晒していた人達と同一人物とは思えない聡明さ。だから学者は本業以外に首を突っ込むなと。本業の立派な功績までぶち壊しになる

まとめ内で触れられてるけど、鹿児島県民としては桜島の山体崩壊が怖い。大正噴火の様に溶岩で対岸とつながったこともあるし。

紹介されてる山体崩壊を予測していた Giachetti et al. (2012) の論文はオープンアクセスになったみたい。 http://sp.lyellcollection.org/content/361/1/79 https://twitter.com/geolsoc/status/1076938367890268160
