For some reason Dutchsinse took his video down (the one that I embedded)…..so I did my own homework. The Tonga Trench looks very active. remember that Hunga Tonga blew up a year ago. The Karmadec Islands got hit (again) but the quakes were shallow. New Zealand has been experiencing a lot of quakes. The plate boundary travels between the islands.
