Book Review: Teruaki Yoshida, "Can We Find Earthquake Precursors? - Multiple Perspective Observation with Radio Waves" (Published: Mar. 2016), Toru Nakagawa, Posted on Amazon site, Jan. 4, 2024) 
(in "TRIZ Home Page in Japan", an. 6, 2024)
Excellent research practice, detailed and clear presentation of real observation data, and impressive educational practices. -- However, other more direct observation methods are beginning to shed light on earthquake precursors.
The research aim of this book can be summarized as: "Using the fact that FM broadcast radio waves from out-of-sight are sometimes reflected by the ionosphere and reach us, we want to observe the effects of earthquakes on the ionosphere, find characteristic precursor phenomena, and create a method for short-term/imminent prediction of earthquakes."
After his intensive research from 1995 to 2012, the author concluded: "With the arrival of seismic tremors, broadband electromagnetic noise was often observed . However, no precursor phenomena related to the earthquake, such as ionospheric disturbances, could be detected."
-- I mention three new observation methods which have detected highly-possible EQ precursor phenomena.
