**Abstract**

The most destructive and unpredictable disasters around the world are determined earthquakes. Various consequences are reported as possible negative effects and therewithal health-related of them. The identification and classification of the different types of health risk factors is an initial goal in an uncomplicated earthquake setting and a fundamental tool to a good understanding and effective organization of the health care system (HCS) in case of complicated medical situation. The health care system works at high tension with considerable difficulties due to the calamity of a large magnitude outbreak of a traumatic defeat such as an earthquake. In conditions of the worst-case earthquake scenario with the subsequent provoked multi-secondary disasters and with multi-secondary risk factors possibilities to take accurate solutions is a real challenge for the health risk manager. They are available critically low resource constraints. Two main critical points are formed. On the one hand the description of a structure of mass victim and achievement high quality medical triage in complicated setting due to earthquakes is a conceptual medical stage of health risk management. On the other hand it is a main step of medical provision of the population and a step of risk reduction strategy.
