Addressing Disaster Risk Reduction by Analyzing Sea Level Rise in the Aceh Waters

Eustatic changes produce changing on global sea levels, such as changes in water volume in the oceans world. This change indirectly affects the balance of water and land and it is very harmful for the archipelago countries which one of them is Indonesia. The two most important effects are the temperature and mass of water stored on land and sea as fresh water in rivers, lakes, glaciers, polar ice caps, and sea ice. Therefore the purpose of this study is to see how far the sea level changes in Aceh waters in relation to disaster risk reduction. To achieve this goal, the method used is to analyze the record of sea level data in the waters of Aceh during the last 25 years. The analysis of sea surface change data in Aceh shows that there has been a linear increase in sea level since 2008 in parallel with the rise in temperature so that it is expected to lose ground in some areas of the Aceh coast.
