| Research Abstract |
A concept of lithosphere-atmosphere-ionosphere(LAI) coupling related to an earthquake has arisen to understand the physical mechanism of pre-seismic ionospheric and atmospheric anomalies[ Kamogawa, Eos, 2006]. In this study, the following results concerning LAI coupling phenomena. Significant total electron contents(TEC) variation in the ionosphere was not also observed during 2011 Fukushima Nuclear power plant accident.[ Kakinami & Kamogawa et al., ASR, 2011]. We discovered another co-seismic ionospheric phenomenon which is that a giant tsunami after the subduction earthquake produces an ionospheric hole, termed a"tsunamigenic ionospheric hole". It is widely a sudden depletion of ionospheric total electron content(TEC) in the hundred kilometer scale and lasts for a few tens of minutes[ Kakinami & Kamogawa et al., GRL, 2012].
