(a) The horizontal component of the acceleration time history (Acc) recorded at the ORIO and ORHO stations (from the earthquake of 24 December 2008). (b) Comparison between the simulated and recorded acceleration time history for the ORHO station. (c) The soil amplification curve based on the recorded time series of the earthquake (ORHO/ORIO) and the soil amplification curve at the ORHO station based on FEM (output–input), using weak motions recorded at the ORIO station as input. The soil profile includes a soft soil deposit of 81 m of Leda clay, underlain with 10 m of glacial till. The agreement between the peak amplification ratios was good, and the calculated fundamental frequency of 0.7 Hz (based on FEM) is close to the observed fundamental frequency of 0.8.

Abstract One of the main challenges facing geological storage is to identify cost-effective methodological workflows for characterizing and monitoring geological storage sites. In the framework of the ALGECO2 project, led by the IGME (Geological and Mining Institute, Spain), a preliminary study of the Lopín site in the NE of Spain indicated conditions were promising for geological storage of CO 2 . However, the poor quality of the legacy seismic reflection data precluded thorough characterization. Within the H2020 PilotSTRATEGY project, one of the possible selected target reservoirs was the Lopín structure. In order to characterize its geometry and physical properties as required to properly evaluate its storage potential, IGME applied a new emerging methodology that integrates reinterpreted reflection seismic data with newly acquired and interpreted gravity, passive seismic and petrophysical data. This methodology was successfully applied along one seismic profile. In this paper, we present the results of this integration as the first step towards characterizing the site and evaluating its suitability for storage.
