Public Health Response (as of 21st May)
At least 5,498 children have been left alone in Sichuan Province's quake zone, either because they have been orphaned or their parents cannot be located
About 4,800 elderly people left alone due to death of their family or they have been separated from all their relatives
32 radioactive sources in affected area
Safely shut down of all nuclear facilities after the quake
No leakage of radioactive substance
Health system responsibility:
Proactive approach to health consequences of radioactive exposure
Collaborate with MEP to make ensure of no radioactive leakage
30 cm movement of China's largest earth-rock dam due to earthquake
400 damaged dams with possible threat to downstream people
26 hours lasting fire
Evacuation of 900 residents due to fears of tank cars explosion
Creating natural dams by moved down rocks into rivers
Formation of 21 lakes throughout the basin
Dangers due to earthquake-created dams:
Instability of the piles of rubble
Bursting the dam by another quake
Downstream floods by cascade of water
Evacuation of thousands of people from Beichuan

Disaster Risk Management
Strategic shift from managing a disastrous event to more preventive and proactive approaches!!
The conceptual framework of elements considered with the possibilities to minimize vulnerabilities and disaster risks throughout a society, to avoid (prevention) or to limit (mitigation and preparedness) the adverse impacts of hazards, within the broad context of sustainable development !
A potentially damaging physical event, phenomenon or human activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation.
What is the Hazard?
The conditions determined by physical, social, economic, and environmentalfactors or processes, which increase the susceptibility of a community to the impact of hazards.
Non-resistant house & school building
The probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environment damaged) resulting from interactions between natural or human-induced hazards & vulnerable conditions.
Risk = Hazards x Vulnerability
A serious disruption of the functioning of a community or a society causing widespread human, material, economic or environmental losses which exceed the ability of the affected community or society to cope using its own resources.
A disaster is a function of the risk process.
It results from the combination of hazards, conditions of vulnerability and insufficient capacity or measures to reduce the potential negative consequences of risk.
What is a Disaster?
Maybe Sichuan was not able to modify the hazard part of the earthquake risk model, and predict it precisely, BUT they could assess their vulnerability conditions and reduced them!
This has been the same experience in Bam & Kashmir, Yogyakarta !
Just-in-Time Education activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation.
Let’s teach the communities right now !
Risk awareness & Knowledge development including education, training, research and information are of the important fields of action for Disaster Risk Reduction!
Information …. activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation.

Please read carefully at:
So, an earthquake measuring 7.9 on the Richter scale is a big earthquake, but not necessarily equal to a disaster. It is just movement of the earth crust. Our vulnerability has changed it to a disaster!!
