Hurricane Irma has become so strong it's showing up on seismometers used to measure earthquakes
Irma颶風增強到可被地震儀紀錄

Stephen Hicks, a seismologist at the National Oceanography Centre Southampton, said seismometer recordings on Guadeloupe, an island group in the southern Caribbean Sea, show the now-Category 5 storm approaching the Lesser Antilles, another Caribbean island group.ꀊ一位NOCS的研究員提到，在南加勒比海群島上的地震儀，記錄下了CAT 5 暴風的逼近

“Seismometer recordings from the past 48 hours on Guadeloupe show Cat. 5 #Hurricane #Irma driving closer toward the Lesser Antilles,” Dr Hicks tweeted.ꀊ原Twitter的文字內容

In a later tweet, Dr Hicks clarified that background noise – for example, wind causing trees to move and crashing ocean waves – was causing seismographs to pick up Irma.ꀊ在後來的貼文中這位研究員提到，由於樹木的搖動以及海浪拍打造成的背景雜訊，才使得地震儀捕捉到Irma



太平洋上的颱風應該也有同樣效果吧？還是我們這區島鏈面積都太大，沒辦法產生相應的震波？
