68% of events here are shallow (under 70 km), 28% intermediate (70–300 km) and 4% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.
By band, the catalogue holds 13 in the magnitude 4 range, 9 in the magnitude 5 range, 3 in the magnitude 6 range.
