Description
This dataset contains seven ambient vibration measurements acquired using two-dimensional arrays of triaxial geophones, as described in Montalva et al. (Under Review). This original dataset corresponds to an earthquake reconnaissance and data collection following the Mw 6.4 Copiapó earthquake on June 6, 2025.
The compressed files are organized as follows: each directory represents a site studied (VS%number), and each folder contains three *.dat files containing synchronized observations across the three components: EW, NS, Z. Each synchronized file includes four columns (for VS1, VS2, VS3, VS4, VS6) and five columns (for VS5, VS7), respectively, which represent the individual sensors in the array.
The location of each site and its corresponding measurements in each array are located in the VS_coords directory.
Funding: EASER (Evolution Assessment of Seismic Risk) project ACT240044 funded by the National Agency for Research and Development (ANID-Chile).
