Abstract On 24 January 2020 (UTC), a destructive Mw 6.7 earthquake struck the east Anatolian fault of eastern Turkey after a series of foreshocks, causing many casualties and significant property damage. In this study, the rupture process of this earthquake is investigated with teleseismic broadband body-wave and surface-wave records. Results indicate that this earthquake is a left-lateral strike-slip event, and the rupture extends mainly to south. The main slip patch spreads ∼30  km along strike in the shallow above 14 km with a peak slip of ∼1.2  m, and the total seismic moment is 1.69×1019  N·m. The east–west component of horizontal surface displacement predicted with our slip model ranges from ∼0.4 to −0.3  m. The predicted displacements are consistent with the observed ones obtained from satellite images. We relocate 459 foreshocks and early aftershocks to explore the relationship between foreshock and aftershock sequences and coseismic slip. It is noted that there is an anticorrelation relationship between the distributions of early aftershocks and the coseismic slip. The strain energy in the large slip patch may have been sufficiently released by the mainshock; therefore, fewer early aftershocks occurred in that patch. Although we note a similar pattern between the relocated foreshock and coseismic slip, and a migration of foreshock, our dataset may not well resolve the correlation and migration due to the incomplete relocation foreshock catalog. Based on the slip model, we calculate the coulomb stress changes on the surrounding faults caused by the mainshock. The results reveal that the mainshock promoted stress accumulation on the northern and southern ends of the Elazig–Matalya segment and may reactivate the locked fault segment, leading to a high seismic risk in these regions. Although this earthquake does not significantly increase the coulomb stress change, the seismic risk of the Matalya–Kahraman Maras–Antakya segment should draw attention.

We apply a single-step, finite-fault waveform inversion procedure to derive a coseismic slip model for the large MW 7.3 Papanoa, Mexico earthquake of 18 April 2014 using broadband teleseismic body waves. Inversion of the P and SH ground-displacement waveforms yields a rupture model characterized by two principal sources of slip in the northwest portion of the Guerrero coast. The region is also the site of several M > 7 earthquakes in 1943, 1979 and 1985. A comparison of the 2014 slip model with ruptures observed for the 1979 and 1985 earthquakes suggests that the zones of high slip do not spatially coincide, despite similarities in the size and location of their aftershock areas. The zones of high coseismic slip are interpreted to represent asperity areas along the Cocos- North America plate boundary, and their limited spatial overlap from one event to another indicates that the rupture characteristics of recurring M > 7 thrust earthquakes in this portion of western Guerrero have not repeated in the last 70 years. The abutting nature of the asperities suggests that future large M > 7 earthquakes are likely to involve interplate patches between areas where large coseismic failure has been recently observed. Also, the observed asperities and their intervening regions may define locations where seismic failure may occur in future megathrust events. The results have important implications for the potential and recurrence of large M > 7 subduction earthquakes and the estimation of the strong ground motions expected from these events.
