The advent of the latest technology has helped us the widespread disaster monitoring at precise location. The GPS, GSM and Wireless sensor network are available at affordable price and it makes them to be used extensively for some of the disasters which were not possible to monitor in a standalone manner in a real time and locate its precise location at far distance and allowing the authorities to mobilize the man, machine resources without wasting the precious time and resources, making this type of system a vital instrument. There are systems in the world but still a indigenous system is needs to be developed by taking in to considerations our problems, because there is vast difference exists between worlds and Indian environmental parameters such as temperature, humidity, rain and geographical structure. Real-time monitoring of environmental disasters is one of the prime necessities of the world. Different technologies have been developed for this purpose. Wireless sensor networks (WSN) is one of the major technology that can be used for real-time monitoring. WSN has the capability of large scale deployment, low maintenance, scalability, adaptability for different scenarios etc. for real-time monitoring. This paper discusses the design and deployment of a disaster assessment and implementation of system using wireless sensor network. This huge damage and casualties can be avoided by such system deployment and maintaining the constant eye over change in the parameters of the location constantly.This fulfills a very important need for any real time monitoring, especially in hazardous or remote scenarios. GPS is being increasingly used also for automated continuous monitoring of landslides and avalanches. For such GPS-based deformation monitoring systems, the accuracy, availability, reliability and integrity of the positioning solutions heavily depend on the number and geometric distribution is being tracked. It is composed of a series of sensors, of easy and rapid installation, which can be positioned directly upon the geogbody, or in the immediate surroundings, to provide conraphical location continuous data on the activity. The SMS technology also enables the user to dialogue with the system, to obtain information on the monitoring operations, either by means of SMS messages. They cause considerable damage to highways, railways, waterways and pipelines. They commonly occur with other major natural disasters such as earthquakes), volcanic activity, and floods caused by heavy rainfall. In many cases, expanded development and human activities, such as modified weather condition and deforestation, can increase the incidence of landslide,flood,hurricane,avalanches,storm disasters. Problem Definition: Here we have used the Zigbee, GSM and GPS modules as earlier we have used GSM and Zigbee. As by using GPS we can have the accurate location of the place As we obtain the information at the receiver side by gsm and pc at receiver station or by SMS we can alert the people and save lives and propertyHere we are proposing a system which is integrated to combine as to
