Shear Wave Velocity Measurements Along the East Anatolian and Narli Faults, in NSF RAPID: 2023 Türkiye Earthquake Sequence

This dataset contains the raw unprocessed active and passive surface wave and horizontal to vertical spectral ratio (HVSR) data collected in 23 sites located along the East Anatolian and Narli faults in Kahramanmaras and Hatay provinces, Türkiye. Surface wave and HVSR data were recorded at all the sites. In this project, each testing site folder contains the unprocessed surface wave data and the metadata file. The active surface wave data was recorded at each site using a linear array of 24, 4.5 Hz geophones with 2 m receiver spacing. Vertical geophones were used to record Rayleigh waves. A central array source was used solely for P-wave refraction, whereas multiple source offsets of 2, 5, 10, 20, and 30 m were used for both the multichannel analysis surface wave (MASW) data and P-wave. The passive microtremor array measurements (MAM) data were recorded using L-shaped arrays. The HVSR measurements utilized six three-component Trillium Compact, 20-second broadband seismometers. The L-array MAM measurements were carried out using 24, 4.5 Hz vertical geophones. An equal receiver spacing of 5 m was used. L-array dimensions ranged from 55 m x 60 m to 35 m x 80 m. The data was used to develop shear wave velocity profiles at each site. The details of the recorded data are provided in the metadata files for each site.
