Seismic signatures reveal fragmentation patterns of fireball meteoroids
Los Angeles CA (SPX) Jul 24, 2025 Seismic data can distinguish between intact and fragmented fireball meteoroids during atmospheric entry, according to a new study published in Seismological Research Letters. Researchers led by Iona Clemente of Curtin University analyzed seismic signals from several fireball events, including the 2020 return of Japan's Hayabusa2 sample capsule, to test this approach. The Hayabusa2 re-entry provided a rare opportunity to benchmark seismic signatures due to the known trajectory and timing of its des ... read more
