OMG look at the ground! This is during the M7.8 earthquake that hit the Philippines a couple of days ago 👀👀

明日(6月12日)は、1978年に宮城県を中心に大きな被害のあった #宮城県沖地震 が発生した日です。死者28名のうち18名がブロック塀などの倒壊によるものでした。外出時には、ブロック塀、看板、ガラスなど身近な危険がないか確認してみてください。

@kmn_terr Well, with peak slip concentrated updip from the hypocenter, I'd assume depth was the limiting factor in tsunami generation? I'd expect this type of rupture geometry to encourage larger tsunami generation, but I guess that is conditional on depth.

@SonoranAstro finally found one so as you requested

The Ladybugs here in Tohoku are like the ones in the US but inverted colors. Black with red spots as opposed to red with black spots.

[Grace Cohen 🌪️ @GraceCWeather]

@patton_cascadia I personally like the term in the volcanic sense but less so in the seismic sense

[Grace Cohen 🌪️ @GraceCWeather]

I kinda forgot this was in the code lol

@ghost42_00 @Gabe529Wx @webberweather Exactly. Not possible to predict.

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx @webberweather Yes, this year is fcst to be significant ENSO wise, however there is no correlation between ENSO and earthquakes, and there is no way to forecast earthquakes. A M8-9 class quake is possible this year just as it is possible any other year.

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx @webberweather 5 largest quakes on record ENSO
1. 5/22/1960 Chile 9.4-9.5: 0.1
2. 3/27/1964 Alaska 9.2-9.3: 0
2. 12/26/2004 Indonesia 9.2-9.3: 0.6
4. 3/11/2011 Japan 9.0-9.1: -0.9
5. 11/4/1952 Kamchatka 8.8-9.0: -0.7

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx @webberweather Correction - +2.7

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx It has no connection. Additionally, the current ENSO is in the weak nino to neutral phase.

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx Major earthquakes occur during el nino, la nina, and neutral phases. ENSO is a measure of SST anomalies while the vast majority of these major earthquakes are due to plate boundaries which occur kilometers under the sfc of the earth.

[Grace Cohen 🌪️ @GraceCWeather]

@ghost42_00 @Gabe529Wx They aren't related

フィリピンでのMw8.2の地震の津波シミュレーションを行った。ISGSの速報モーメントテンソルで初期波源を計算。地形はGebcoを用いてメッシュを間引いた。海溝軸の深いところに沿って津波が速く伝わっている。日本近海で局所的に大きくなるところもありそうだが、現在の解像度では確認できない。
