Fig. 3: Vertical cross-sections of Vs and ξs perturbations across the transects in Fig. 2a.
From: Low-velocity anomaly in the Coral Sea associated with subducting slabs and the Woodlark rift
a Vs cross-section along transect Aa. Black dots represent events with magnitudes from 4.5 to 8 during 2004–2021 from the GCMT catalog49. b Vs cross-section along transect B-b. Dashed lines in the sections B-b and D-d indicate depths of 80, 160, 270, and 410 km from top to bottom. c ξs cross-section along transect A-a. A red dotted circle highlights the region with a negative radial anisotropic anomaly linked to the Coral Sea plume upwelling. d ξs cross-section along transect B-b. e Vs cross-section along transect C-c. The yellow line indicates the geometry of the subducting Solomon Sea slab from the Slab2 model58. f Vs cross-section along transect D-d. g ξs cross-section along transect C-c. The gray line represents the geometry of the subducting slab. h ξs cross-section along transect D-d. i A vertical cross-section of SEMUCB-WM110 along 154°E displays a clear vertical low-velocity anomaly extending from the core-mantle boundary beneath the Coral Sea, indicated by a red rectangle.
