Chilean liquefaction database = Base de datos chilena de licuación.

Abstract

This research describes a liquefaction database that contains a summary of 209 liquefaction, non-liquefaction and marginal case histories compiled from 2010 Mw 8.8 Maule, 2014 Mw 8.2 Iquique, 2015 Mw 8.3 Illapel, and 2016 Mw 7.6 Melinka seismic events, where the liquefaction phenomenon caused damage to buildings, bridges, roads, and drainage systems, generating millions in losses at the infrastructure level. The database structure is organized into three main tables defined as site information, geotechnical tests, and seismic parameters. The main tables include the location of the sites, surface evidence of liquefaction or the absence of them, geotechnical parameters from boreholes, geophysical and laboratory tests. In addition, seismic parameters of these seismic events are included as well as also ground motion intensity measures estimated for the sites. Intensity measures included are peak ground acceleration and velocity, pseudo-spectral horizontal acceleration and Housner intensity. The information in this database will allow a better characterization of the seismic demand and the geotechnical properties of the soil involved in the prediction of liquefaction triggering. The data associated with this article are available in DesignSafe (https: // XXXXX), where users can freely download and process data, to train or evaluate predictive liquefaction models.
