Query: Epicenter localization using forward-transmission laser interferometry   Widely distributed optical fibers, together with phase-sensitive laser
interferometry, can expand seismic detection methods and have great potential
for epicenter localization. In this letter, we propose an integral response
method based on a forward transmission scheme. It uses spectrum analysis and
parameter fitting to localize the epicenter. With the given shape of the fiber
link, the integral phase changes of light propagating in the forward and
reverse directions can be used to determine the direction, depth, distance of
the epicenter, and seismic wave speed. For the noisy case with SNR=20 dB, the
maximum localization error for the orientation angle is ~0.004{\deg}, the
maximum error of the P-wave speed is ~0.45 m/s, the maximum localization error
for the epicenter depth is ~1000 m, and the maximum localization error for the
epicenter distance is ~2200 m.
