Coastal Hazards of Indonesia

Indonesia is surrounded by water on all sides, so of course they  are prone to extreme coastal hazards. The shoreline is not just affected by the erosion and subsidence against the shoreline, but also by the tsunamis, earthquakes and weather changes which affects the relative sea level. Erosion along the coast affects seaside homes and buildings. Central Java and Tegal and especially prone to this erosion because the of their sea cliffs and coastal structure.

The combined shoreline of Indonesia is approximately 80,000 Km. That's a lot of coastline. The water level is constantly changing because of the amount of tectonic movement and the heightened tidal activity. The long shore movement of sediment also contributes to erosion of Indonesia's landscape. The government in Indonesia has taken some measures to prevent coastal erosion, by implementing seawalls and beach groins were it is necessary, but these structures are not in all areas, so home and buildings are still suffering from these coastal areas. Indonesia is a popular place to visit from tourists, especially Jakarta and Java. The coastline needs to be protected to keep the coast a thriving place for tourists and locals alike to enjoy the beauty of the land.
