The view is toward the SE. Black lines represent depth contours spaced 100 km apart, and blue lines are the intersection of the slab with the profiles given in Fig. 1a. The location of the deep-focus earthquake cluster mentioned in the text is marked in blue. The volcanoes of the Changbaishan volcanic field, marked by red triangles, are projected onto the 0 km depth surface. The 670 km depth surface, approximately marking the top of the lower mantle, is shown in purple. Red arrows mark potential paths of upwelling from the lower mantle through the slab gap created by the penetrating slab segment.
