These exposed data indicate that the city of Chone is located on deposits of alluvial plain sediments and old strata of colluvial deposits, causing them to have unfavorable conditions in terms of soil behavior [30]. Table 3 lists the description by stratum of the Unified Soil Classification System (USCS), the geological units, shear rates and geological ages with their respective thicknesses. The surface strata identified between 1 and 8 m deep have shear rates that vary between 100 and 150 m/s belonging to the Holocene. With respect to the stiff colluvium alluvium deposits, there are soft to medium compact strata with a Vs ranging from 150 to 400 m/s between depths of 8 and 22 m. The deepest strata of ancient alluvial-colluvial deposits are sedimentary deposits with compactness that varies with depth from soft to firm between 15 and 18 m with Vs ranging from 180 to 300 m/s and soils with firm compactness that are located at greater depths at 25 m presenting Vs greater than 500 m/s. This analysis was realized in order to first classify the geological units describing which soils are liquefiable where they are considered probably liquefiable when the liquid limit (LL) is less than 37% and the plasticity index (PI) is less than 12% [56]. These would correspond to the soils of the city of Chone at depths between 8 and 14 m deep. Any loose soils with PI < 12 and wc/LL > 0.85 are the most susceptible to liquefaction, while loose soils between 12 < PI < 20 and wc/LL > 0.8 are more resistant to liquefaction but still these are susceptible to cyclic mobility [57]. Figure 7 illustrates the susceptibility results of liquefiable soils based on the criteria proposed by [PERSON] et al. [56], where the perforations are indicated with their respective LL and PI, evidencing that non-liquefiable soils present higher LL values, from 37% to 82%. These soils present Holocene strata up to 15 m deep with soft to medium compactness and with a degree of saturation (Sr) close to 100%. All these characteristics make them potentially liquefiable soils that belong to alluvial deposits. For the Pleistocene strata that correspond to depths of 15 to 25 m with moderately dense compactness, belonging to alluvial-colluvial deposits, they indicate (Sr) between 77% and 86%. Table 4 illustrates the geotechnical results according to their geological units of the tests performed as Fc, Sr, LL, PI, and N\({}_{\text{ISPT60}}\) corresponding to the city of Chone. It is indicated that the laboratory tests performed on saturated sands for the liquefaction phenomenon are determined by three main factors. First, the higher the void ratio in the soil, the more easily liquefaction will occur. Second, the lower the confining pressure, the more readily liquefaction will occur. Finally, the higher the cyclic stress, the lower the number of cycles required to induce liquefaction [58]. The content of low plasticity fines does not necessarily provide a higher resistance to liquefaction, and with respect to the grading effect of sands, it is concluded that the triaxial cyclic strength of a well-graded specimen decreases to a lower limit value when adding low plasticity fines up to about 20% [59]. According to the geotechnical results, the strata intercalated between sands and silts that present these soils of the city of Chone vary the
