Geodetic polygons for an Alaska-Aleutian subduction zone interface earthquake recurrence model

This dataset represents polygons used to approximate areas of geodetic coupling for use in the 2023 update of the USGS National Seismic Hazard Model for Alaska.本数据集收录用于近似大地测量耦合（geodetic coupling）区域的多边形要素，服务于美国地质调查局（USGS）2023年对阿拉斯加地区国家地震灾害模型的更新工作。
