Figure 1

Seismicity map around the Tonga subduction zone, where the Pacific Plate subducts from the Tonga Trench. The coloured points show earthquakes during 2002–2017, the magnitudes of which are ≥ 4.5 as per the Advanced National Seismic System (ANSS) Comprehensive Earthquake Catalog (ComCat). Colour indicates focal depth. The beach-ball symbols and the red labels indicate the global Centroid Moment Tensor (CMT) solutions for large earthquakes, with magnitudes ≥ 7.4. The brown squares and labels indicate the Global Navigation Satellite System (GNSS) stations and their names.
