Fig. 1: The location of triggered tremor, triggered earthquake, and strong-motion stations, and the ground-motion excited by the 2023 Turkish mainshocks in the Jordan and Jezre’el valleys.
From: Tremor along the Dead Sea Transform remotely triggered by the 2023 MW7.6 Kahramanmaraş earthquake
Inset map show the Eastern Mediterranean region with the the MW7.8 and the MW7.6 locations indicated by stars. The rectangle indicates the location of the study area, and dashed lines are for political borders. a Yellow triangles, star, and diamond indicate the location of the TRUAA strong-motion (SM) stations, triggered tremor, and triggered earthquake, respectively. Purple lines are for mapped faults59. Digital elevation model provided by the Advanced Land Observing Sattelite mission60. DSF: Dead Sea Fault; CFF: Carmel-Fari'a Fault; MS: Mediterranean Sea; SG: Sea of Galilee; JE: Jenin; KS: Kirbhet Samara; JEV: Jezre'el Valley. b, c The surface-wave induced ground motions in the Jordan and Jezre'el valleys. The difference in percent between the PGVs of the MW7.6 and the MW7.8 mainshocks is denoted by ΔPGV and equal to \(100\times (PG{V}^{{M}_{W}7.6}-PG{V}^{{M}_{W}7.8})/PG{V}^{{M}_{W}7.8}\) is shown by the black dashed curve. The root-mean-square of the dynamic velocity gradients due to the MW7.8 and the MW7.6 are shown by the red and dashed red lines, respectively. The axes convention is shown in the legend in panel (a), with the radial and transverse directions denoted x and y, respectively. The location of the triggered tremor projected onto profile A–A' is indicated by the yellow star in panel (b), and the location of the triggered earthquake projected onto profile B–B' is indicated by the yellow diamond in panel (c). b The 64 to 32 s transverse ground velocity gradient, denoted by \({\dot{u}}_{y,x}\), as a function of position along profile A–A'. c The 32 to 16 s radial ground velocity gradient, denoted by \({\dot{u}}_{x,y}\), as a function of position along profile B–B'.
