Vertical displacements at Guayanilla Bay (epicentral region of the Jan. 7, 2020 event) inferred from InSAR analysis using the Sentinel-1 satellite (Fielding, pers. comm). Focal mechanism (beachball diagram) for Jan. 7, 2020 magnitude-6.4 event, and was used to predict static offsets at campaign GPS stations (white arrows) provided by D. Mencin et al. (2020).
