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. An 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 seconds to tens of seconds warning prior to ground shaking during an earthquake. Earthquake Alarms Systems is a methodology designed to provide warnings in earthquake prone regions around the world [2] . The warning messages provided by such systems can be used to reduce the damage, costs and casualties in an earthquake. Earthquake mitigation system is truly important in order to prevent tremendous destruction in an area, especially in the civil residence [3] , [4]. Even a few seconds can allow time to take protective action such as taking cover in safe locations, stopping elevators and opening doors at the nearest floor, or automatically stopping critical processes to mitigate damages or to enhance public safety [5] . For the countries, which are located in the ring of earthquake prone areas, the fast information is required to be known for faster action of rescuing and medical helps. The condition of surrounding near the center of earthquake must be transmitted immediately in the real time in order to act responsively to the location [6], [7] . One of the problems is, the distance between prone earthquakes areas to the office of earthquake-observation is quite far and however, the lead-time for earthquake is much smaller. The communication through wired network is also not feasible in such scenario. By using camera in some points of locations, we propose a solution to directly transmit the condition of places near the center of earthquake wirelessly through GPRS or 3G network. The basic approach of our proposed system is that a sensor senses an area which is already being placed in an earthquake prone area; moreover, a camera records the video of the surrounding environment. The system immediately transmits the sensing information to the desired location using 3G communication. The rest of the paper is organized as follows. In Section II, we explain our proposed algorithm along with the system design. Sections III is devoted to the experiment set up.
In our previous work REF , we demonstrated an earthquake detection system with the integration of wireless network to transmit the data and video of the earthquake location as a crowdsourcing IoT data model for disaster management.
