Science Alert  July 1, 2022 The initial explosion and subsequent plume triggered atmospheric waves which propagated around the world multiple times. An international team of researchers (UK, USA – industry, University of Massachusetts Lowell, Virginia Tech, University of Colorado Boulder, NASA Goddard Space Flight Center, Catholic University of America, Germany, Australia, France) show the details of this response, using a comprehensive set of satellite and ground-based observations to quantify it from surface to ionosphere. A broad spectrum of waves was triggered by the initial explosion, including Lamb waves propagating at phase speeds of 318.2±6 ms-1 at surface level and between […]
