Earthquake patterns based on diurnal and semidiurnal electromagnetic emissions related to earthquakes/volcanoes observed with 24 h periodicity

Electromagnetic (EM) emissions related to earthquakes and volcanoes were observed in a very wide frequency band from VLF to microwave. These were found to be diurnal and semidiurnal type occurring only during certain hours of the day. It was also found in these examples that the occurrences of earthquakes/eruption of volcanoes were simultaneous with the timings of these EM emissions. From this study, it can be concluded that the semidiurnal stresses on the earth and on the moon are solely caused by the position of the Sun. The causes of diurnal stresses are not precisely known. In order to study the variation of the stresses developed over a longer period of time, the earthquakes for various regions of the globe were mapped for number of years on 24 h basis. The histogram of earthquakes thus generated on 24 h basis (HE24H) provided various patterns. It was observed that most earthquakes were aligned to some curvature representing some kind of stress fronts of different strengths and lasting up to over 100 years. They were also found in different shapes and sizes. The study of HE24H also supports the hypothesis that the occurrence of earthquakes is synchronous to the earth's rotation.
