硫黄島沖合で海水変色 海底噴火か
4月29日 21時41分

29日午後、小笠原諸島の南にある硫黄島の沖合で海水が変色しているのが確認され、気象庁は「海底噴火が発生した可能性がある」として、周辺の海域などでは火山活動に警戒するよう呼びかけています。

気象庁によりますと、29日午後3時40分ごろ、硫黄島の北東1.5キロの沖合で、海水が青く変色しているのを海上自衛隊が上空から確認しました。
このため気象庁は、29日午後7時すぎ、「硫黄島の北東沖で海底噴火が発生した可能性がある」と発表し、周辺海域を航行する船舶などに今後の火山活動に警戒するよう呼びかけています。
硫黄島は小笠原諸島の父島の南230キロ余りにあって、6年前の平成18年以降、島全体が膨らむ傾向の地殻変動が観測され、先月には島の西部にある火口でごく小規模な水蒸気爆発が発生しました。さらに27日以降、島内で小規模な地震活動が活発化して、これまでより大きな地殻変動が観測され、29日午前4時半ごろからは一時火山性の微動も観測されていました。
硫黄島には現在、海上自衛隊と航空自衛隊の基地がありますが、一般の住民は住んでいません。

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
