A fiber-optic sensor based on singlemode-multimode-singlemode (SMS) fiber structure was proposed and demonstrated for measuring both amplitude and frequency of seismic wave signal. This sensor system consisted of an amplified spontaneous emission (ASE), SMS fiber probe and photodiode detector. A seismic wave generator was used as a seismograph stimulator. The SMS fiber probe was attached onto a loudspeaker to gather an acoustic pressure which was modulated by a seismograph signal from the audio generator. The proposed seismic wave sensor has the capability to measure the seismograph signal operating within a frequency range from 2.0-2.6 Hz with a linearity of more than 98%. This sensor is advantageous due to its simplicity of the design and low fabrication cost while exhibiting good sensitivity and dynamic range. It is also suitable to be applied in real field to detect volcano eruption.
