Standard spectral ratios (SSR) on earthquake recordings of stations of the 6N network during the activities of the EMERSITO INGV emergency group in Ancona (Italy) following the 2022 MW 5.5 Costa Marchigiana-Pesarese earthquake

These files contain the results of the standard spectral ratios on the earthquakes (SSR) recorded by stations of the temporary network 6N, installed by the INGV EMERSITO emergency group at Ancona (Central Italy, Marche Region) for about 4 months after the start of a seismic sequence in the Adriatic Sea in 2022. The mainshock of the sequence occured the 9th of November 2022 and its moment magnitude was 5.5. Eleven stations, equipped with velocimeters and accelerometers, were deployed at Ancona, at about 45-50km from the epicenters of the sequence. They recorded both ambient noise and aftershocks of the sequence; the complete dataset can be accessed under the European Integrated Data Archive (EIDA) using the link: 10.13127/sd/qctgd6c-3a.

The files are formatted as four column separated by commas; the first column is the frequency in Hz, the second the average SSR, the third is the average SSR minus one standard deviation, the fourth is the average SSR plus one standard deviation. The first row is the header.

The stations are named as: CMA05, CMA06, CMA07, CMA08, CMA09, CMA10, CMA11, CMA12, CMA13, CMA14 and CMA15.

Station CMA15 has been used as reference site for SSR calculation.

These HVNSR are presented as figures inserted in the station sheets that is going to be published in a summary paper in Earth System Science Data (ESSD) journal with the doi: 10.5194/essd-2024-162.
