Research Theme

The three-dimensional ionospheric anomalies and disturbances induced by natural disasters

Abstract

Natural hazards are naturally occurring phenomena closely associated with seismic origins (e.g., earthquake and tsunami), meteorological and hydrological origins (e.g., typhoon, thunderstorm, and mudslide). In 1960s, the local ionospheric disturbance which locates in 60 - 1000 km above the Earth’s surface, caused by the 1964 M9.2 Alaskan earthquake opened an promising possibility for disaster prediction and real-time monitoring based on the space-based observation.

Our research focus on visualizing and analyzing the three-dimensional (3-D) ionospheric disturbed structures caused by seismic and meteorological activities. The 3-D evolution of ionospheric electron density perturbations before, during, and after various disaster events will be systematically investigated using the Global Navigation Satellite System and the computerized ionospheric tomography technique. We devote ourselves to exploring the pre-earthquake ionospheric anomalies, the space-based monitoring for seismic and meteorological activities and to improving the real-time warning system. The lithosphere-atmosphere-ionosphere coupling mechanism will be reexamined and further optimized based on the 3-D visualized results in the future.
