Implementation of Escarpment Alarm System Using Terrestrial Reference System

Abstract

Abstract-An earthquake warning system is a system of accelerometers, communication, computers, and alarms that is devised for regional notification of an earthquake while it is in progress. earthquake mitigation system is truly important in order to prevent tremendous destruction in an area, especially in the civil residence. therefore, with the aim of building a substantial escarpment alarm system and mitigating its disastrous effect, in this paper, we propose an earthquake detection system with the integration of wireless network to transmit the data and video of the earthquake location. the Arduino module is used as a part of camera. the raspberry pi is connected to the earthquake detection sensor which is a product of Korean technology company, GMG ltd (geotechnical monitoring group). the GPS data of the earthquake location and the video is transmitted in the real time using HTTP and FTP protocol. the proposed algorithm has been implemented in the real prototype. the experiment results show that the sensor transmit the data of an earthquake prone area to the server and cellular mobile. I. INTRODUCTIONAn earthquake is caused by the release of stored elastic strain energy during rapid sliding along a fault. The sliding will start at some location and progress away from this hypocenter in each direction along the fault surface. The speed of the progression of this fault tear is slower than and distinct from the speed of the resultant pressure and shear waves, with the pressure wave traveling faster than the shear wave. The pressure wave will generate an abrupt shock while the shear waves can generate a periodic motion (at about one cycle per second) that is the most destructive in its effect upon structures, particularly buildings that have a similar resonant period, typically buildings around eight floors in height. These waves will be strongest at the ends of the slippage, and may project destructive waves well beyond the fault failure. The intensity of such remote effects are highly dependent upon local soils conditions within the region and these effects are considered in constructing a computer model of the region that determines appropriate responses to specific events [1]. In its most generic sense, the word earthquake is used to describe any seismic event whether a natural phenomenon or an event caused by humans-that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments. An earthquake's point of initial rupture is called its focus or hypocenter. The term epicenter refers to the point at ground level directly above the hypocenter.Although no one can reliably predict earthquakes, today's technology is now advanced enough to be used to rapidly detect seismic waves as an earthquake begins to happen, calculate the maximum expected shaking, and send alerts to surrounding areas before damaging shaking arrives; this is called Earthquake Early Warning. Earthquake early warning can provide a few secon...
