Combining Swarm Langmuir probe observations, LEO-POD-based and ground-based GNSS receivers and ionosondes for prompt detection of ionospheric earthquake and tsunami signatures: case study of 2015 Chile-Illapel event

Abstract: The study investigates ionospheric electric field responses to the earthquake (EQ) of magnitude 8.3, and to the related seismic activity and tsunami triggered by the mainshock in Chile-Illapel region, at 22:54 UTC, in the evening of 16.09.2015. The work is a wider review of available ground and satellite data and techniques available in detection of seismically induced traveling ionospheric disturbances (TID) and irregularities of smaller scale. The data used in the experiment includes several types of ground … Show more

“…We propose in this work a methodology that potentially detects earthquake and tsunami related signatures in the topside ionosphere, mainly based on the POD data from GNSS receivers on board LEO satellites: This method is called the PIES approach (POD-GNSS LEO Detrended Ionospheric Electron Content Significant Deviations technique). PIES extends the applicability and scope of our previous multi-technique study of Chile-Illapel 2015 Mw8.3 event [39] to other events. The method includes three steps: the acquisition of significant characteristics, the identification and issuance of warnings, and the external validation.…”

“…It is possible that the processing of LEO data requires a spectral approach more than time series from a ground station do, as the disturbed signal is less pronounced in transient LEO observations. Fortunately, the frequency domain has been analyzed more frequently in LEO data in recent years [35,[51][52][53][54]. These studies are encouraging us to take a further step and try a spectral classification of specific patterns that refer to different Ne and TEC signal disturbances.…”

“…Mogi (1969) studied the seismic activities around the focal area before the strong earthquake in Japan, and proposed for the first time that the frequency of earthquakes might increase or decrease significantly. Many subsequent studies have shown that there are frequent anomalous seismic signs around the focal points before most strong earthquakes, such as the 1988 Armenia Spitak Ms7.0 earthquake (Wyss and Habermann, 1998), 1992 US Landers Ms 7.3 earthquake (Wiemer and Wyss, 1994), 2011 Japan Ms 9.0 earthquake (Katsumata, 2011), 2014 Chile Iquique M W 8.1 earthquake (Aden-Antoniow et al, 2020) and the 2015 Chile Illapel M W 8.3 earthquake (Jarmolowski et al, 2021). Therefore, it is of great significance to study the abnormal variation characteristics of earthquake frequency for the development of earthquake prediction.…”
