Fig. 2: Space-time tracking of the rupture front.
Location of the radiating point of the fault at every second (squares) with color-codes radiation time. Horizontal error bars show the uncertainty associated to the position of the radiating points and are mostly an effect of the 10-s time window adopted to compute the polarization vector, as described in the “Methods” section. The error bars displaying this uncertainty are rotated from along the fault for better readability. Black dots mark the modeled fault planes (as reported in ref. 6) projected over the surface. Blue shaded dots show the epicenters of the aftershocks of the first 10 days (size is scaled by magnitude and light blue points mean shallower events). Black crosses mark the edges of the Gölbaşi basin, while violet crosses display the along-strike limits of the segment of the Pazarcık fault capable of generating seismic sequences and earthquakes with a magnitude larger than 2.54. The numbers in red show the distances in km measured along the strike direction (sketched as a red arrow) from the epicenter of some radiating points. The star marks the epicenter position. The red circle close to the epicenter shows the position of the minimum of the error function (measured as the difference between theoretical azimuths and measured polarization azimuth averaged over the stations) fixing potential radiating points on a planar grid with 0.1°-step both on latitude and longitude. This point is plotted as a black diamond in the Supplementary Fig. 13.
