This article presents a correlation model for pseudo acceleration, peak ground acceleration, and peak ground velocity residuals using a database of Mexican subduction interface earthquakes at rock sites (NEHRP class B). A mixed-effect regression model, a ground motion model and 40 event recordings (418 records) with moment magnitude between 5 and 8 were used to develop a magnitude independent correlation model. This region-specific model yields consistently higher correlation values compared to similar studies developed for shallow crustal regions and other subduction zones worldwide, particularly for pseudo acceleration values at distant periods. These results support the idea of using a region-specific and mechanism-specific correlation model for Mexico’s subduction zone.
