Based on the catalogue data from Fujian digital seismic network, a total of 3 720 earthquakes that occurred in Fujian from 2010 to 2023 are selected to study the local magnitude (ML) deviations. The magnitude residual method is used to obtain a new calibration function (R3(Δ)), station correction values (Sj) and medium propagation direction correction values (Sθ) which are applicable to Fujian, enhancing the accuracy of local magnitude measurement. The results indicate that standard deviation of magnitude deviations decreases from 0.29 to 0.19 after correction. In order to improve the accuracy of earthquake warning magnitude measurement, we apply the first station's magnitude, resulting in the standard deviation of magnitude deviations decreases from 0.31 to 0.25. It is evident that the new calibration function, station correction values and medium propagation direction correction values exhibit strong practicality in Fujian.
