Quality assessment for site characterization at seismic stations

Abstract Many applications related to ground-motion studies and engineering seismology benefit from the opportunity easily download large dataset of earthquake recordings with different magnitudes. In such applications, it is important have a reliable seismic characterization stations introduce appropriate correction factors for including site amplification. Generally, networks in Europe describe properties station through geophysical or geological reports, but often ad-hoc field surveys are missing done using indirect proxy. It then necessary evaluate quality characterization, accounting available information, measurements procedure reliability applied methods obtain parameters.In this paper, we propose strategy be included metadata. The idea that good should larger ranking respect one poor incomplete information. proposed metric includes computation three indices, which take into account indicators, their number importance, together consistency defined scatter plots each single pair indicators. For purpose, consider seven indicators identified as most relevant companion paper (Cultrera et al. 2021): fundamental resonance frequency, shear-wave velocity profile, time-averaged over first 30 m, depth both seismological bedrock, surface geology soil class.
