Research

Research Topics, Overview of the research

• Research Topics

  Variety of phenomena, including electromagnetic ones, that occur in association with or prior to earthquakes

• Overview of the research

  Various kind of anomalies, including electromagnetic phenomena, has been reported to occur in association with earthquakes. However, reliability of such reports has not been sufficiently examined; consequently, their theoretical background has not been established. I am trying to (1) distinguish actual anomalies from apparent anomalies, and to (2) build up candidates theories explaining the actual anomalies related to earthquakes.
