All-sky imaging of transglobal thermospheric gravity waves generated by the March 2011 Tohoku Earthquake

摘要

abstract_textpWe report on imaging measurements of thermospheric gravity wave signatures in 630 nm and 557.7 nm nightglow that suggest an association with the M = 9 Tohoku (Japan) earthquake on 11 March 2011. The propagating waves were recorded in all-sky images at the El Leoncito Observatory, Argentina (31.8 degrees S, 69.3 degrees W), which is located 17,080 km from the earthquake epicenter, almost at the global antipodal point./p/abstract_text
