In this study, we present a local magnitude (M _L) relation for the earthquakes recorded from the Texas Seismological Network (TexNet) between the dates of 1 January 2017 and 31 July 2019. Using a comprehensive seismic dataset from earthquakes in Texas, we propose a distance correction term − log A ₀, which is consistent with the original definition of the Richter magnitude. The proposed distance correction calculation for the TexNet events accounts for the attenuation characteristics of the direct and refracted waves over different distance ranges. Regression analysis of Wood-Anderson amplitudes results in the following trilinear function, which represents the attenuation attributes of the events under investigation: (equcation prensent) in which R _hyp is the hypocentral distance (km). The derived distance correction relationship results in an accurate M _L relationship for Texas that is unbiased over a 200 km distance range. Compared with other M _L relations, the proposed relation in this study gives lower M _L values over all distances than those calculated by Richter (1958), Hutton and Boore (1987), Babaie Mahani and Kao (2019), and Quinones et al. (2019) by an average of 0.01, 0.12, 0.16, and 0.15 units, respectively; this study's proposed relation gives higher M _L values over all distances than those calculated by Scales et al. (2017), Yenier (2017), and Greig et al. (2018) by an average of 0.28, 0.01, and 0.08 units, respectively.
