Reflection of Earthquake Source Process in the Ionosphere could pave way for deciphering earthquake precursors using space-based observations

New Delhi, November 24, 2023. Earthquake processes, even relatively smaller ones, have their reflection in the ionosphere, as they influence the amplitudes and periods of coseismic ionospheric perturbations (CIP) along with factors such as geomagnetism and line-of-sights geometry, according to a novel study. The finding can help observing earthquake source processes from the space which may pave the way for deciphering earthquake precursors using space-based observations. Coseismic vertical crustal movements excite acoustic waves (AWs) in the atmosphere. The waves propagate upward, reach the ionosphere, causing disturbances in numbers of electrons along the line-of-sights connecting ground Global Navigation Satellite System (GNSS) receivers and satellites. These disturbances are call...
