Dataset of relative seismic velocity variations (dv/v) of R66E3 Raspberry Shake and groundwater level variations of BSS002NNZL borehole from 2022/04/28 to 2025/02/04

Dataset of relative seismic velocity variations (dv/v) of R66E3 Raspberry Shake and groundwater level variations of BSS002NNZL borehole from 2022/04/28 to 2025/02/04.

A Raspberry Shake RS3D, a three-components geophone (station R66E3 and network code AM) with a natural frequency of 4.5 Hz (electronically extended to 0.5 Hz), is installed in the technical room located 8 m from the BSS002NNZL borehole (a groundwater monitoring borehole), in the town of La Trinité, Martinique. 

Seismic recordings for station R66E3 (network AM: https://doi.org/10.7914/SN/AM) are collected from the Raspberry Shake data center (https://data.raspberryshake.org/fdsnws/). The raw continuous seismic recordings and relative velocity variations are processed by using MATLAB (https://mathworks.com).

This dataset contains the resulting 2-3 Hz frequency range relative velocity variations data. 

The dataset also contains daily mean groundwater level data (in altitude and pressure) of BSS002NNZL borehole. The borehole is equipped with a PARATRONIC SNP pressure sensor with data recording every minutes. The probe resolution is ±1 mm.

Rainfall and air temperature are available close to the site thanks to the French climatic network operated by Météo-France (meteo.data.gouv.fr). Daily rainfall (from Morne des Esses station) and daily air temperature data (from Spoutourne station) are also provided in the dataset.
