Popis:	As the most destructive natural disaster, earthquake may cause catastrophic demolition which leads to devastating outcomes. Earthquake’s hypocenter is a point associated with spatial footprint, occurrence time, and magnitude. Open source point process modeling is adopted to detect the possible interactions among earthquakes with spatial features, temporal characteristics and effect of the other covariates. Integration of geologic variables in the point process models is suggested for the investigation of the magnitude 6.1 earthquake and the aftershocks occurred on Jun 30, 1975 in Yellowstone National Park. A Multitype Strauss Process Model is utilized, and it successfully captures the spatial pattern of epicenters under the effect of interaction radii among different types of earthquakes. In addition, the distance to faults and earthquake focal depths are implemented as the geologic variables in explaining the seismic pattern.
