The October 2010 eruption of Mt Merapi (the most active volcano in the Indonesia that erupts at 5-years intervals) claimed 141 lives, injured 453 people and displaced at least 278,000 people. This geological event became a disaster as national and international agencies had to step in to assist the Yogyakarta Province and Sleman District Administrations in dealing with the devastation caused by the pyroclastic flows. Because of its cyclic nature the task of the local governments is to improve the hazard mitigation system and to increase the resiliency of the population.
On 22 July 2013 the Volcano spewed ash clouds and people of two villages of the Cangkringan Sub-District evacuated themselves to the local village halls. The hazards posed by the ash clouds of the volcano and by the displacement of vulnerable populations, did cause certain physical and emotional sufferings, but could be controlled by the local administration.
Objective
To examine whether the danger zone District Health Office (DHO) and sub-district Health Centers (HCs) were employing an inter-disaster Public Health Surveillance-Response (PH S-R) System after the October 2010 Mt Merapi eruption and a pre-disaster PH S-R System during the July 2013 Mt Merapi eruption.
