Task 1 (WG-T1): Empirical flatfile generation

(Rodolfo Puglia, Chiara Felicetta, Emiliano Russo, Giovanni Lanzano)

The main issue of the task is the compilation of a qualified dataset of recorded waveforms. The accelerometric dataset is mainly based on European Strong Motion Database and on ITalian ACcelerometric Archive. It has been integrated by velocimetric data, because, in the study area, the strong-motion data are lacking and, on the other side, velocimetric networks are denser.

Data collection includes the reviewing and processing of earthquake recordings from stations on various site conditions (rock and soil) and the compilation of available metadata into a flatfile (magnitude, distance, site conditions, etc.). The ground motions have been adjusted to the reference rock conditions using scale factors (cf. Moscatelli et al. 2014). The metadata have been updated and completed as much as possible, in order to implement complex functional forms for GMPEs testing and calibration.

Flat-file (named "HYPST_emp_db.zip") is available as "Supplemental Materials" in "Products" section.
