前駆電磁波観測による一地震予知法

Recently it is often announced that an abnormality of electromagnetic wave is observed before an earthquake. Especially, a time series of it in Hanshin-Awaji Great Earthquake tells us the possibility of an earthquake prediction. We get the observation results in Niigata-Chuetsu Earthquake (October 23,2004; M6.8) and Sanriku oiling Earthquake (November 15,2005; M6.9). The relation between the frequency of abnormal electromagnetic wave and the outbreak time on both logarithms graph are expressed as the experimental equations, as well as the case of Hanshin-Awaji Great Earthquake. These equations are effective to foresee an outbreak time of earthquake and its magnitude. On the other hand, another method of the earthquake prediction is also introduced according the consideration for the distribution of observation points on the above graph.
