Sentinel-1 InSAR time series analysis of Le Teil earthquake

LOS displacement maps extracted from a one-year time series analysis of Sentinel-1 data (between early January 2019 and late January 2020), processed using NSBAS software (Doin et al., 2011). The following maps results of the temporal decomposition (pixel by pixel) of the time series output.

TS_fit_cos.tif: coseismic step extracted from the time series (cm)

TS_fit_cos_sig.tif: associated misfit (cm)

TS_fit_lin.tif: linear velocity extracted from the time series (cm/yr)

TS_fit_lin_sig.tif: associated misfit (cm/yr)

TS_fit_res.tif: residual displacement after the removal of the coseismic step and the linear velocity from the time series (cm)

TS_RMS.tif: Root Mean Square network misclosure associated with the time series inversion (rad) (Lopez-Quiroz et al., 2009)
