Title

Using Indonesia to Find Relationships between Earthquakes, Volcanoes, and the Change in Earth's Angular Acceleration

Abstract

Using a correlational statistical analysis we looked for possible temporal relationships between earthquakes and volcanic events in one of the most active tectonic regions known. A record of more than 10,000 earthquakes and 500 volcanic eruptions was used for these analysis. This data was analyzed using SAS and Excel Software.  Comparing volcanic eruption frequency in Indonesia to a change in the equatorial length of day shows a significance probability of 0.067. Numbers greater than .1 are inconsequential, and numbers less than .05 are significant. Earthquakes are less promising when compared to a change in the equatorial length of day with a significance probability of more than 0.126.
