## 3 Methodology  
This study compiled knowledge of the tectonic structures from the Granada Basin to the Campo the Dalias to frame this sector within the current evolution of the Betic Cordillera (Figure 2). The former was addressed through the integration of existing and new geological, seismological, and geodetical data. The geological data included the geometry of structures, kinematic data, and pale-ostress determinations from the latest faults. The main active fault data were taken from the Quaternary Active Fault Database of Iberia (Figure 2 and Table 1) which considers the fault described as active in indexed publications [40; 47]. To determine the latest paleostresses, we summarized all data on brittle structures with evidence of recent activity. Orientation data from striated microfaults (Figures 2 and 3 and Tables 2 and S1) provided information about the stress ellipsoid that was active in the region [114]. These data were taken from [PERSON] [41], [PERSON] et al. [42; 43], [PERSON] [44; 45], and [PERSON] [46] and were calculated using the methods of [PERSON] et al. [115] and [PERSON] and Gonzalez-Lodeiro [116]. Figure 3: Rose diagrams of minimum horizontal stress axis (\(\sigma_{\rm hmin}\)) in each sector and type of faulting [41; 42; 43; 44; 45; 46]. Grey: all data together; green: normal faulting; blue: strike-slip faulting; red: reverse faulting. The minimum horizontal stress axes correspond to a \(\sigma_{3}\) in normal and strike-slip faulting, and to a \(\sigma_{2}\) in reverse faulting. In the case of \(\sigma_{1}\) vertical and prolate stress ellipsoid, both \(\sigma_{2}\) and \(\sigma_{3}\) are considered as \(\sigma_{\rm hmin}\). In the case of \(\sigma_{3}\) vertical and oblate ellipsoid, no axis is considered as \(\sigma_{\rm hmin}\). The seismological data consisted of recent seismicity, earthquake focal mechanisms, and stress tensors obtained from earthquake focal mechanism solutions (Figure 4). Seismicity was obtained from the seismic catalogue of the Spanish Instituto Geografico Nacional (IGN), which provides information about the zones with the most active brittle deformation [33]. Focal mechanisms report on active structures at depth and are used to determine present-day stresses [117; 118]. The M \(>\) 4.5 earthquake focal mechanism solutions are depicted in Figure 4. The reduced stress tensors (Table 3) calculated for the eastern Granada Basin [104; 119] using the Win-Tensor(tm) code developed by [PERSON] [120] and [PERSON] [121] were also considered. Moreover, the reduced stress tensors of the intermediate seismicity [88] were calculated using FSA software [122; 123]. We also considered the results of the right dihedra diagrams [117] from the 1988 Agron series in the central Granada Basin [43], the westernmost Granada Basin [44], the Campo de Dalias-Northern Alboran Sea [38], and intermediate seismicity [88]. \begin{table}

Reduced stress tensors [88; 104; 119], right dihedra diagrams [38; 43; 44; 88], and earthquake focal mechanism with M \(>\) 4.5 are shown [124; 125; 126; 127; 128]. R indicates the axial ratio defined by R = (\(\sigma_{2}-\sigma_{3}\))/(\(\sigma_{1}-\sigma_{3}\)).
