Recent results and analysis of theoretical possibilities

(1998-2002)

Related mainly to Frontier-RIKEN and Frontier-NASDA

projects in Japan (1996-2001). Some results were published in

the books:

Atmospheric and Ionospheric Phenomena Associated

with Earthquakes, edit. by M. Hayakawa, 1999;

Seismo-Electromagnetics (Lithosphere-Atmosphere-Ionosphere

Coupling), M. Hayakawa and O. Molchanov,edits. 2002

Main conclusions:

-ULF and AE emissions appears several hours around date of

large EQs, probable due to water motion near the ground surface

• Precursory changes in ULF impedance ratio appears several

days before large EQs, but their origin unclear

• There are reliable precursory changes in VLF sounding data related to

perturbations near atmosphere-ionosphere boundary several days around

large EQ date

• LIACS was found from reliable statistics of the satellite data, but the coupling

is weak and its mechanisms not well-understood
