Abstract This study explores the relationship between planetary positions and earthquake activity using statistical analysis of data from the National Geophysical Data Center / World Data Service (NGDC/WDS) Global Significant Earthquake Database, specifically focusing on NOAA global R5 + earthquake data from 1900 to 2023. The analysis examines correlations between the mean number of earthquakes per day over two-year intervals and the mean heliocentric acceleration of selected planets during the same periods. Results for Jupiter, Saturn, Uranus, and Neptune suggest interesting correlations between planetary acceleration and the mean daily number of earthquakes. Due to sample size constraints, this analysis could not be applied to the inner planets Mercury, Venus, Earth, and Mars. Additionally, the statistical bias resulting from uneven time and earthquake data density prevents a similar analysis for Pluto. Nevertheless, the findings for the four outer planets are intriguing and provide compelling evidence of a possible influence of planetary positions on earthquake activity. * Corresponding Author e-mail aasimazooz1@yahoo.com
