### A-DInSAR at Local Scale
In addition, the majority of the landslide events were produced along the cliffs located between the town of Salinas and El Cuerno beach. Here, the slopes can exceed 60\({}^{\circ}\) in inclination. Their orientations are predominantly towards the N and E (0-135\({}^{\circ}\)). Figure 7 shows the LOS mean velocity maps obtained by PSIG and GEP in the Salinas Area. According to PSIG measurements (Figure 7a, Table 4), the VLOS rates obtained range between \(-\)10.2 and 5.3 mm year\({}^{-1}\). The total number of PS detected was 3417 (885.2 PS km\({}^{-2}\)). They were distributed between the urban, rock cliff, and outcrop reflectors. With respect to the accumulated displacement measured, a minimum and maximum of accumulation of -27.6 and 23.5 mm were detected. As to LOS rates measured, the stable PS represents 98.3% (3360 PS). In the case of negative PS (from \(-\)10.9 to \(-\)2.5 mm year\({}^{-1}\)), there are only 11 PS (0.3%). The positive PS with velocity rates of 2.5-4.6 mm year\({}^{-1}\) (46 PS, 1.4%) stands out compared to those with negative deformation velocity, of which there were only 11 PS (0.3%). Moreover, all detected active PS were isolated and surrounded by stable PS. This makes it difficult to identify areas with deformation because the entire area can be considered as a sector without movement. In the case of the LOS mean velocity map of GEP (Figure 7b, Table 4), the VLOS were between \(-\)7.4 to 9.8 mm year\({}^{-1}\). The total number of PS was 459 (118.9 PS km\({}^{-2}\)). The accumulated displacements ranged from \(-\)17.1 to 18.9 mm. An important fact was the predominance of positive velocities (2.5 to 9.8 mm year\({}^{-1}\), 167 PS, 36.4%). There were only 8 PS with negative velocities of \(-\)2.5 to \(-\)7.4 mm year\({}^{-1}\) (1.7%). Stable PS represent 61.9 % of the total (284 PS). Besides, in both LOS mean velocity maps there was a massive lack of PS in the central area, due to the fact that there was a wooded area. It can be appreciated that the A-DInSAR approaches have not detected ground movement in the problematic slope instability zone (Figure 7). In the case of PSIG, the few PS detected on these slopes show a LOS mean velocity of 1.2 mm year\({}^{-1}\). Thus, we have chosen some deformation areas detected with GEP and have analyzed them with respect to PSIG and geospatial data in order to distinguish the movements linked to ground deformations from noise or other artifacts. Different time series were presented (Figure 7c) and were described below. The time series shown have been selected according to: (i) GEP deformations detected and (ii) the most representative deformations. Each deformation time series shows only one target, with the PS number, the mean VLOS (mm year\({}^{-1}\)) and the accumulated deformation (mm). TSI: The TS measured by PSIG (TS-Ia, Figure 7c) do not present a deformation trend and their pattern is chaotic. The accumulated displacement is 4.2 mm. On the other hand, the GEP TS (TS-Ib, Figure 7c) presents a certain tendency of increasing deformation between January 2018 and May 2019. In this trend, the deformation achieves a displacement of 4 mm. However, there are some jumps in April and June 2018, and between May 2019 and February 2020 that make it difficult to read the TS. The accumulated deformation reaches a displacement of 2.4 mm. GEP TS presents a LOS mean velocity of 2.1 mm year\({}^{-1}\). TSII: situated in the Northeast of the Salinas area, in the town of Salinas itself. According to PSIG, the LOS velocity observed here is 2.8 mm year\({}^{-1}\). On the other hand, 2.7 mm year\({}^{-1}\) was measured by means of GEP. In the case of the PSIG, the TS (TS-Ila, Figure 7c) presented a period of increasing deformation between January 2018 and October 2018. The displacement measured was 4 mm. Afterward, there was a stabilization stage,
