地震作为破坏性最强的自然灾害，可能造成破坏性的破坏，造成毁灭性的后果。地震的震源是一个与空间足迹、发生时间和震级相关的点。采用开放源点过程模拟方法，结合地震的空间特征、时间特征以及其他协变量的影响，对地震之间可能存在的相互作用进行探测。本文提出用点过程模型中地质变量的积分来研究1975年6月30日黄石国家公园发生的6.1级地震及其余震。利用多类型施特劳斯过程模型，成功地捕捉到了不同类型地震相互作用半径影响下的震中空间分布。此外，在解释地震图象时，将距断层的距离和震源深度作为地质变量。
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.
