From Fishnet Stockings to Falling Apples: Earthquake Interaction on the Scale of a Fault to the Planet

從「網襪」到「落下的蘋果」:從斷層尺度到全球尺度中的地震互動

Ross will use QuakeCaster, a demonstration apparatus he developed, to explore the fundamental riddle of earthquakes: Why quakes are sporadic when the forces that drive them are steady. QuakeCaster also provides a way to visualize how researchers are making progress in the difficult problem of earthquake forecasting. Using computer animations and slides to extend the demo into three dimensions, he will delve into the strange world of earthquake interaction and triggering. These illustrate how stress triggering can make sense out of earthquake sequences in California, Turkey, Taiwan, and Japan. Finally, Ross will argue that very rarely, megaquakes can trigger large aftershocks all over the globe.

Ross 將使用一項由他親自開發的演示裝置:QuakeCaster,來探索原始的地震謎題:“為何驅動地震的力量持續施加,但是地震僅偶而發生?”。QuakeCaster也提供了一種視覺方法,說明目前研究學者在地震預報這個困難問題方面的進展。Ross將使用電腦動畫與投影片將演示延伸至三維尺度,以探索地震互動與觸發中的奇妙世界,他演示了地震如何依序發生,並相互關聯,讓發生在加州、土耳其、臺灣與日本等各地的地震先後序列關係變得有意義。最後,Ross將會主張,巨大地震能夠在全球各地觸發大規模的餘震。
