Over the last few decades, a numbers of countries have set up disaster management information systems according to their own specific needs. Disasters are unpredictable and occur suddenly like earthquake, floods, drought and cyclone etc. Communication facilities for disaster management system is most important act as it convey at the right time communication in disaster,it may handle disaster and helping to decrease it.
Two type of information needs in disaster management
Pre disaster information: Question arise that how to get pre disaster information? It is getting from the research and analysis department of the geography in the country.
Post disaster information: After the disaster, our first job is to find out where and where it was occurs. What is the next step to help people?
Now a days Satellite communication play a major role in disaster management communication. Communication facilities can be set up for rescue and relief operation purposes. That type of early warning system developed at the different area’s by itself.
Here are the disaster communication facilities:
DCWDS Digital Cyclone Warning Dissemination System set at Delhi and other coast area. It is for the pre disaster information.
The WLL - VSAT system is in terms of handsets which can be easily taken inside of the affected areas and sends information by direct audio communication.
The MSS Type C reporting terminal developed for the sending short messages directly through satellite in remote area.
AES-SNG is a system which can send video pictures of the affected area for online review from the control center.
Tele medicine: It is one more step for the disaster management communication. In this system, on line help can be provided from the hospital and super specialty doctors. Only connect up link to laptop or PC and get the online information about cure.
Can you have some information about communication facilities for disaster management?
Satellite communication can be used for early warning besides creating awareness and education in the disaster prone areas. One of the early warning systems developed at the center is the Digital Cyclone Warning Dissemination System (DCWDS). Such a system is being planned to be deployed at IMD, Delhi and other vulnerable areas on the coast. Communication facilities can be set up for rescue and relief operation purposes. The WLL - VSAT system has provision for handsets, which can be easily taken, inside the affected areas. Similarly, audio alarms can be sent out to selected areas using digital sound broadcast system. An interactive distance education system is available for imparting training to the staff with two-way data transmission and building up of a database at a central location. Such a system has provision for image transmission of affected areas besides facilities like video conferencing. The MSS Type C reporting terminal developed at the Centre is available for sending short messages directly through satellite. Likewise, the Sat-phones can be deployed for most effective audio communication from remote areas. In the case of the recent Bhuj Earthquake, the Center has demonstrated the setting up of a communication link between Bhuj and Gandhinagar by deploying the AES-SNG. Such a system can also send video pictures of the affected
site for online assessment/ instructions from the control center. Tele-medicine is another area wherein on line help can be provided from bigger hospitals and super specialty doctor/ s. A web camera connected to a laptop PC with uplink facility can be effectively used for tele-medicine consultation. In the response phase of a disaster, the remote sensing techniques can be used for an effective and accurate assessment of the affected area/ s. One of the earliest study in this direction was carried out by the Center was for the 1977 Andhra cyclone which caused a large-scale...
