We present a calibration framework for a Microwave Frequency Fiber Interferometer (MFFI) aimed at estimating earthquake distance and magnitude, with the long-term goal of enabling early warning capabilities. This marks the first demonstration of calibrated MFFI sensing for quantitative seismic parameter retrieval
