2. Critical infrastructure risks
3. Environmental risks
Critical infrastructure are systems whose incapacity or destruction would have a debilitating impact on the defense or economic security of nation. They include communications, electrical power systems, gas and oil, highways, pipelines. These kinds of services are essential and provide real value to the public. So, high among the concerns in protecting these systems from harm is ensuring the continuity of service.
(2) Causes of damages
Critical infrastructure systems usually get damage by two factors: natural and human-made. In the natural realm, earthquake like San Francisco in 1906 and Kobe in 1995 cause serious damages to infrastructure. And also extreme winds, flood, snow, tsunamis, wildfires pose risk. Analyse the past events, improved prediction and forecasting system, and better construction have enhanced the ability of infrastructure systems to withstand all types of hazard. But crippling failures of these systems still occur.
(3) Impact of critical infrastructure system failures
However, critical infrastructure systems become increasingly complex and interdependent. So hazard mitigation must also be concerned with the secondary and tertiary failure effects. And the more systems are become complex, we need to recognize the significance of the impact of complex infrastructure system failur
