Days before the strike: precursory waveform decoherence preceding major strike-slip earthquakes. Stretching results

This dataset contains the stretching results of cross-correlation functions using station pairs for Ridgecrest, CA, Turkiye (EAFZ), and Aegean Sea (NAT). The dataset is compressed in a tar.xz. To decompress, use tar -xvJf filename.tar.xz. Download and decompress the cross-correlations dataset named WF_DEC_DATA.tar.xz.

Description of the data and file structure

The dataset is organized by study area as follows: ZONE (Aegean, Ridgecrest, Turkey) each zone contains a directory named "stretching" (stretching results).

Sub-directories "stretching" contain sub-directories named according to station pairs (e.g., XXX_YYY) storing *.npz files organized by stacks and frequency bands corresponding to results after applying the stretching technique. 

The directories pre_postZZ present in each main region directory (e.g., WF_DEC_DATA/RIDGECREST/stretching/CCC_TOW2/pre_postZZ), can be used to plot dv/v and waveform coherence variations before and after the mainshocks.
