The influence of geomagnetic storms on global main shock earthquake occurrence: A study of solar wind parameters and seismic activity
Year: 2025
Type: article
Abstract: This study investigates the relationship between geomagnetic activity and earthquake occurrences, focusing on 17 earthquake main shock events influenced by geomagnetic storms. The analysis reveals complex patterns in earthquake behaviour that are shaped by a combination of factors, including tectonic activity, regional geological conditions, and geomagnetic disturbances. The findings indicate that while larger earthquakes tend to be associated with regions of moderate tectonic activity, the frequency and magnitude of earthquakes are not solely determined by the Tectonic Index. Additionally, variations in time delays between earthquake events suggest that regions with shorter delays experience more frequent seismic activity, whereas areas with longer delays may witness less frequent but larger events. The study gives a potential earthquake magnitude equations related to solar wind pressure and Electric field parameters.
