Hurricane Irma has become so strong it's showing up on seismometers used to measure earthquakes
Irma飓风增强到可被地震仪纪录
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的研究员提到,在南加勒比海群岛上的地震仪,记录下了CAT 5 暴风的逼近
“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的文字内容
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在后来的贴文中这位研究员提到,由于树木的摇动以及海浪拍打造成的背景噪声,才使得地震仪捕捉到Irma
太平洋上的台风应该也有同样效果吧?还是我们这区岛链面积都太大,没办法产生相应的震波?
