Ah, because it’s an island arc formed by a subduction zone? Duh...

Correct. The Indonesian Archipelago is the same way, and so is off the west coast of North America from Eureka, CA all the way to the north end of Vancouver Island.

The west coast has far less compressional force on it, essentially just the east edge of the spreading centers of the Juan de fuca, Explorer and Gorda plates and the mostly subducted Nazca, all producing the fractional melting facilitating the cascade volcanoes. Of course it gets big earthquakes, but geologically speaking it’s the slacker side of the ring of fire.
