Solar Activity is One of Triggers of Earthquakes with Magnitudes Less Than 6

摘要

Possible triggers of earthquakes such as tidal stress, rainfall, the building of artificial water reservoirs, mining, and extraction of fossil fuels have been discussed in the literature. Furthermore, solar activity has been also speculated to be a trigger of earthquakes. In this article, we tackle this problem by data analysis based on machine learning, wherein we used physical measurements of solar activity and related variables for predicting frequencies of earthquakes on the entire earth. From the analysis of actual data, we conclude that solar activity is one of the triggers of earthquakes with magnitudes from 3.0 to 5.9. In addition, we show that the Earth's electric field is the most effective variable related to earthquakes.
