The Lau Ridge?

I’m not sure … w/out doing any research, the Lau Basin would be the back-arc basin, so the Lau Ridge is the western boundary of that … but the origin of the ridge itself I’m not sure. One possibility is that it’s the older, now-abandoned arc for the system.

I had been more or less assuming that the trench ESE of the volcano was the subduction source of that volcanism, but hadn’t seen it confirmed anywhere. What is the parallel linear feature to the west? And that video is outstanding! Thanks.
