Investigating two Potential Events of Intraplate Induced Earthquakes
Abstract
In this work the characteristics of two recent intraplate seismic events apparently induced by human activities are investigated. These events include a M=5.2 earthquake potentially induced by mining activities in Arizona, and a swarm of earthquakes in Northeastern Mexico potentially induced by fluid injection. For each region, we will investigate the physical and statistical characteristics of the swarms. For the case in Arizona, a numerical geodynamic model is developed to investigate whether mining activities caused stress changes large enough to trigger the M=5.2 event. The parameters obtained from this study are expected to provide information about the processes (tectonic or anthropogenic) responsible for intraplate earthquake triggering or induced seismicity.
