<span>In this work we implemented STA/LTA trigger algorithm, which is widely used in seismic detection, using Hadoop MapReduce. This<br />implementation allows to find out how effective it type of tasks as well accelerate the detection process by reducing processing time. We tested our implementation on a seismological dataset 14 broadband stations and compare with traditional one. The results show that MapReduce decreased time 34% compared implementation.</span>
