Extended Data Fig. 3: The arrival of shock front at TK:4614.
From: Near-field evidence for early supershear rupture of the Mw 7.8 Kahramanmaraş earthquake in Turkey
(a) A to-scale schematic of the location of the TK:4614 station relative to station TK:NAR and the epicenter. Green triangles indicate the location of the stations. The epicenter is marked by a yellow star. The red front indicates the shear wave propagation front while the straight black lines represent the shock fronts (Mach lines) associated with supershear speeds. Station TK:4614 is located further away from the Narli fault relative to TK:NAR or TK:4615 rendering theoretical estimates of local rupture speed using ground motion record complex. (b) The strong ground motion at stationS TK:NAR and TK:4614 shows the phase arrival times between the two stations. (c) The strong ground motion (FN and FP) at TK:4614 shows a clear separation between the arrival of the initial peak of the FP and FN components.
