Mega earthquake in Japan

NHK 31 Jan 2025 A Japanese government panel says an anticipated megaquake in the Nankai Trough along Japan's Pacific Coast could kill up to 298,000 people -- down slightly from an estimate made more than a decade ago. There is said to be a roughly 80 percent chance that a magnitude 8 to 9 quake will occur along the trough within the next 30 years. Nagoya University Professor Emeritus Fukuwa Nobuo submitted the panel's report to Disaster Management Minister Sakai Manabu. Sakai expressed his belief that damage can be reduced if measures are implemented and action is taken based on plans. He said the government will do what it can to promote the measures. The report says the quake's maximum magnitude will be on the range of nine. Seismic intensity is expected to be at least lower 6 on Japan's scale of zero to 7 in 24 prefectures, and 7 in 10 other prefectures. The panel estimates tsunami at least 10 meters high could reach Tokyo and 12 other prefectures between the Kanto...

Geologyhub YouTube   長週期震波   Ncree   FTVnews 美國地質調查局專家耶克:「這次緬甸地震特別嚴重,是因為震央靠近人口密集區,一道淺層斷層引發強烈震動,震央又離住宅區很近。」 美國專家點出,震源深度淺會引起地表強烈震動,加成破壞力。更別提這次主震的強度本來就大,震央還恰巧落在緬甸人口密集區。日本學者補充,斷層快速滑移產生的長週期震波,也會進一步拉大受災範圍。 緬甸強震/中泰越災情也慘重 專家:長周期震波加劇災情 東京大學地震研究所教授 酒井慎一 :「(震源)淺的地震加上長周期震波,常會影響到更遠的地區,就算距離(震央)較遠,大樓之類的高層建築,也可能受到劇烈搖晃危害。」 長週期震波只要朝同一個方向傳遞,就會加快擺動速度,對高樓大廈等大型建物產生強大脈衝。以這次發生地震的緬甸中部「實皆斷層」為例,儘管震央距離泰國曼谷近1000公里遠,但因斷層是往南破裂,位於南方的曼谷震感本來就會特別強烈。加上曼谷是個盆地,地質鬆軟,加劇「場址效應」。 東京科學大學教授田村修次:「曼谷是鬆軟堆積的地層,這樣鬆軟的地層容易使地震波增強,耐震性低的(高層建築)就可能倒塌。」 Deep low frequency effect   場址效應   wiki 無樑版設計   kknews   patent   Fb Curiosity channel fb

內地啤酒被驗出嘔吐毒素 未知會否令人類患癌

  在大家最關注的安全測試當中,消委會測試8種常見於啤酒的霉菌毒素,結果顯示1款樣本「哈尔滨」麥道 檢出脱氧雪腐鐮刀菌烯醇(Deoxynivalenol,DON),檢出量為每公斤26微克,其餘樣本未有檢出霉菌毒素。脱氧雪腐鐮刀菌烯醇(DON)又稱為嘔吐毒素(vomitoxin),主要由禾穀鐮刀菌及黃色鐮刀菌產生,這些產生DON的霉菌可在土壤中找到,是穀物(尤其是小麥及玉米)的致病菌。DON最令人關注的是安全問題,有可能令人在攝入後30分鐘內出現噁心、嘔吐、腹瀉、腹痛,甚至發燒等徵狀,與其他胃腸道疾病的徵狀相若,不易分辦。國際癌症研究機構(IARC)把某些鐮刀菌衍生的毒素(包括DON)列為第3組物質,即未知會否令人類患癌。 根据深圳海关食品检验检疫技术中心在中国电子口岸数据中心深圳分中心微信公众号2023年7月的发文,DON是一种常见的真菌毒素,大多在低温、潮湿和收割季节,在谷物庄稼中慢慢生长,一般在大麦、小麦、玉米、燕麦中浓度较高,在黑麦、高粱、大米中浓度较低。 哈爾濱麥道啤酒樣本中DON的檢測含量遠低於中國國家標準(谷物及其製品)(1000μg/kg,即1ppm),也遠低於國際權威食品安全機構的相關上限標準(低於<1ppm, 即1000up/kg) 。所有產品在上市前均經過嚴格測試。
