The principles of disaster management Cycle means undertaking all activities at different time like Reducing risk to potential hazards before disaster occur with the help of development both short and long term strategies Make sure the appropriate response and assistance to the affect areas during and immediately after disaster Achieve quick and sustained recovery and rehabilitation after the disaster took place.

Communication facilities for disaster management include Digital Cyclone Warning Dissemination System (DCWDS) it is used pre hazard information. The WLL – VSAT in used for audio communication facility. The MSS Type C reporting uses for sending message through satellite. For online and video facility AES-SNG system in very helpful.

In order to understand the principles of disaster mitigation it is important to clearly understand the phases of disaster management cycle like mitigation, preparedness, response, relief & recovery and disaster management.

Disaster Mitigation

Mitigation is the use of strategies to reduce risks prior to, during and post disaster. It is related to short term and long term measures for example, preventing or reducing risk properly or lives by improving the inherent capacities of people and strengths of habitants, infrastructure and critical facilities.
