Strong Motion Database – SIBER-RISK
SIBER-RISK (called by the initials of SImulation Based Earthquake Risk and Resilience of Interdependent Systems and NetworKs) is a project led by professor Juan Carlos de la Llera and co-investigators Paula Aguirre and Gabriel Candia, and funded by Fondecyt grant #1170836. The project started in April 2017 and it aims to investigate, develop, and implement a conceptual framework to evaluate earthquake vulnerability, risk and resilience of geographically Distributed Network Systems (DNS).

During the development of the project, the idea to create an extensive and well defined strong motion database of Chilean earthquakes arised. Used in different tasks, this database has proven to be incredibly useful for researchers and students in their projects.

In order to reach more people, we finally have published it online, entirely free. We only ask you to follow our licensing terms. Finally, we do not take any responsibility in any result or analysis made from this database.

Flat file

In this database you can find more than 1800 events and 7600 records. The following parameters are tabulated for each record: start time of the record, magnitude, hypocenter location, type of event (crustal, interface or intraslab), depth, station name, station location, hypocentral distance, epicentral distance, rupture distance, Joyner-Boore distance, Vs30 (if available), and azimut (if available). The table can be accesed here: flatFile.xlsx. Also, spectral accelerations with damping ratios of 0.02 and 0.05 are available for all records here: SpectralValues.xlsx.
