             abstract = "The ionosphere hosts co-seismic ionospheric disturbances (CID or 
                         ionoquakes) during earthquakes due to Seismo-Atmosphere-Ionosphere 
                         (SAI) coupling. This phenomenon involves seismic vibrations at the 
                         Earth's surface triggering coupled energetics into the atmosphere 
                         and ionosphere in the form of various atmospheric/plasma waves.

                         (TEC) measurements from Global Navigation Satellite System (GNSS) 
                         receivers, and magnetometers have revealed ionoquakes as potential 
                         candidates for monitoring earthquake energetics in space. The 
                         continuous coverage provided by GNSS networks around the globe has 
                         made it possible to monitor disturbances in TEC around seismic 
                         faults with high spatial/temporal resolutions and to detect 
                         ionoquakes unambiguously. However, one of the unresolved issues in 
                         ionospheric seismology is the early detection of near-field 
                         ionoquakes, in less than 8 minutes from the earthquake onset. In 
                         this study, we demonstrate that large earthquakes can generate 
                         ionoquakes that are detectable as early as 400 seconds after the 
                         earthquake onset and 250-430 seconds after the peak vertical 
                         ground velocity, based on GNSS-TEC data and using the 
                         SAI-analytical (SAI-ANA) simulation code. The SAI-ANA code was 
                         recently developed to simulate the SAI coupling, starting from the 
                         analytical solution of the equations used by Kherani et al. (2016) 
                         to model atmospheric gravity waves (AGWs) and their interaction 
                         with the ionosphere. This study is the first to reveal the rapid 
                         arrival of gravity waves at ionospheric heights and the 
                         development of ionoquakes in less than 7 minutes from the start of 
                         the earthquake. Additionally, it is the first simulation to 
                         capture the occurrence of rapid ionoquakes within a simulation 
                         time of 2-3 minutes, significantly faster than their development 
                         and detection within 8 minutes.",
