Displacement and Subsidence on Mt. Mantap, North Korea

Caption

3-D displacements derived from radar imagery with arrows indicating horizontal, color indicating vertical motions spanning the explosion and about 1 week of additional deformation. Black outline derived from ALOS-2 coherence loss indicates the substantial surface disturbance and large displacement gradients caused by the explosion over an area of about 9 square kilometers. Thin gray lines are topographic contours at 100-meter intervals. Red square in the upper right inset shows the location of Mt. Mantap in North Korea. Red stars indicate the locations of previous nuclear bomb tests. Beach balls show locations and focal mechanisms of the Mw 5.24 and Mw 4.47 events on Sept. 3, 2017
