<![CDATA[Disaster events will have an impact on the stability of the social order. Mitigation is structural and non-structural steps taken to limit the adverse impacts caused by natural hazards, environmental damage and technological hazards. Mitigation measures in terms of their nature can be classified into 2 (two) parts, namely passive mitigation and active mitigation. Vulnerable groups in society that must receive priority during a disaster are pregnant women, mothers giving birth and babies. The impact of disasters on pregnant women is abortion and premature birth because mothers easily experience stress, both due to hormonal changes and environmental pressures around them. Children who experience a disaster feel afraid, sad and in pain because they have experienced trauma. Disasters also affect children's future growth and development.
