The iSTEP (integrated Study and Test for Earthquake Precursors) project goal is to study characteristics of seismo-ionospheric precursors in the total electron content and develop lithosphere-atmosphere-ionosphere (LAI) coupling models finding possible causal mechanisms for the large earthquake prediction and forecast of the globe. The project consists of a main project and three sub-projects (Sub-project I: Seismo-ionospheric/atmospheric precursors, Sub-project II: Seismo-lithospheric precursors, Sub-project III: Statistics for earthquake hazard). The Main project operates the integrated ground-based seismo-electromagnetic observation system in Taiwan and develop physical models to find possible mechanisms. The integrated observation system including seven networks of magnetometers, infrasonic wave systems, atmospheric electric field mills, Doppler sounding systems, ionosondes, GPS receivers, and all sky cameras. The observation system is used to monitor earthquake precursors in the lithosphere, the atmosphere, and the ionosphere, and to find the LAI coupling in Taiwan. Currently, it is the most comprehensive ground based system, which acts a reference for the earthquake precursor studies of the world. Meanwhile, Main project will utilize existing ionospheric physics models, such as TIEGCM, SAMI3, etc. to reproduce seismo-ionospheric precursors (SIPs) and seismo-atmospheric precursors (SAPs) observed by Sub-project I and seismo-lithospheric precursors (SLPs) by Sub-project II finding possible causal mechanisms and searching the LAI link. The observed and simulated precursors in the lithosphere, atmosphere, and ionosphere of a certain event will be further compared with its associated statistical results of Sub-project III to assess the hazard.
