Mw 7.0 or greater earthquakes that occurred along the Indo-Australia and Pacific Plate boundary since 1950 for the Solomon Islands region. The moment tensors with stars indicate the events in this study (Mw 7.6, and Mw 7.4). The blue beachballs indicate the focal mechanisms of single earthquake events and the red beachballs indicate earthquake doublets or multiplets. The light blue arrows indicate the Indo-Australia and Pacific Plate rates relative to the plate boundaries which are indicated by the thick black lines. Focal mechanisms are from the Global CMT Catalog data, Ekström et al. 2012)
