【注目|南海トラフ地震臨時情報発表後のM8クラスの地震発生確率を政府が修正】 政府は、過去の地震データの対象期間を広げるなどして、大地震後に同程度かさらに大きな地震が起きる確率を修正しました。 臨時情報の期間に発生しなかったとしても、臨時情報が発表されたら備えの再確認をしましょう。










Lund et al.(1998) report that high-resolution paleomagnetic records from western North Atlantic deep-sea sediments reveal that the Earth’s magnetic field experienced at least 14 local excursions since the last global polarity reversal 780,000 years ago, with these excursions coinciding with similar events identified globally, indicating they are not regional anomalies but instead represent a recurring and integral component of geomagnetic behavior between reversals. These authors reconstructed geomagnetic field behavior over the past 1.2 million years and identified excursions using criteria including true excursional directions, reproducibility across multiple cores and sites, and consistent placement within secular variation patterns, with stratigraphic analysis showing numerous Brunhes-aged excursions that can be correlated with previously identified events such as the Laschamp and Blake excursions, supporting the conclusion that such events are globally synchronous and far more common than previously recognized, “Most of the excursions occur in neighboring bundles of two or three, with intervening intervals of distinctive (large amplitude) secular variation, Altogether, the bundles tend to last 20-50,000 years, These bundles of closely spaced excursions may indicate a continuing excursional state or pattern in the core dynamo process which spans the duration of the bundles, Although each individual excursion probably contains only 1000 to 2000 years of true excursional directions, the bundle time intervals, including the intervening distinctive secular variation, may altogether represent more than 20% of Brunhes time.” Polarity transitions such as the Brunhes–Matuyama boundary were rapid, possibly occurring within ~1000 years and preceded and followed by clusters of excursions: “Our initial analysis of the onboard paleomagnetic results suggests that we may need to significantly alter our view of what constitutes typical geomagnetic field behavior between polarity reversals, Moreover, the results indicate that excursions appear to be intimately related to both normal and transitional geomagnetic field behavior.” Lund et al. (1998) Geomagnetic field excursions occurred often during the last million years agupubs.onlinelibrary.wiley.com/doi/epdf/10.10…


Thanks. To add to this, if people really want to dig into whether astro images are AI-generated or not, don't ask Grok, don't use AI detection software, load them into astronomy.net, and see if the stars line up with reality. AI is terrible at detecting AI.
