Abstract— Seismology is the scientific study of earthquakes & the propagation of seismic waves through the earth. The big advances in seismology are done from around 1900 and onwards. This advancement helps in making more sensitive seismographs so that earthquakes could be properly located. In the last ten years, recording devices completely replaced their old analog system by digital systems. The latter systems are costly, large in size, require specialized maintenance and are incompatible with computer data processing and analysis. In this paper, a recent development in seismic data acquisition has been focused. A cost-effective, small size seismic data acquisition system is proposed based on ARM. The system consists of an Accelerometer sensor for sensing seismic signal and an Alarm to inform about arrival of the earthquake. Index Terms — Seismic Data Acquisition, Earthquake, Accelerometer, ARM, ADC I. INTRODUCTION An earthquake is a natural disaster which can cause damage and loss of lives. It is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Degree of the damage caused by an earthquake depends upon the distance between the affected area and the epicenter, and also upon the magnitude which indicates how much energy is released from the origin to the Earth’s crust [1]. Analysis of seismic signals is done by seismometers at monitoring stations. Seismometers are sensors that sense and…show more content…
CONCLUSION This paper highlights different aspects regarding seismic data acquisition system. According to the survey the data acquisition systems already available are costly, large in size and are restricted to modification or upgrade. Also, these systems require specialized maintenance and are incompatible with computer data processing and analysis. The proposed system is low cost, small size seismic data acquisition system which is compatible with computer and can analyze seismic signals for prediction of the
