• Resumen

  • Aiming at recognizing the prints in the most recent sedimentary record due to earthquakes, able to develop liquefaction and fluidization in sediments (magnitude equal to or more than 5), we have studied eight boreholes, each about 40 m long, located in the Low Segura basin (Alicante, Spain). We have recognized disturbances due to the own boring activity, as well as others due to bioturbation, thixotropy in clayey levels and to what, in our opinion, is the effect of seismic shocks (microfaults, distorted lamination and fluid scape structures)
