Abstract
This paper was briefed about difficulty in seismic refraction during data acquisition on peat soils. Seismic refraction is commonly used for subsurface characterization. This method can determine the subsoil profile by differentiate its soil velocity. Peat is known with high compressibility and more 75 % of organic content that give challenges is seismic refraction. Challenges of seismic refraction such as attenuation of seismic wave, poor signal to noise ratio (S/N) and seismic source energy explained in this paper. This problem is common for geophysicist but technical purposes for engineering community is good to have better data acquisition. The purpose of this paper is to shown proper data acquisition for seismic refraction on peat soil. The raw data of seismic wave taken from seismograph for takeout spacing of 1, 3 and 5 m are shown in results and discussion for comparison of seismic data quality.
