Indonesia is currently embarking on a transition from a ‘risk retention’ to a ‘risk transfer’ strategy for managing the impact of disaster events. The risk transfer strategy, i.e., insurance policy and protection, requires high-level preliminary risk assessment, which requires detailed attention and analysis in producing hazard mapping. Improvement...
In the last two decades, several devastating wave-induced events such as the 2004 Indian Ocean tsunami, 2011 Tohoku tsunami and the 2018 Palu tsunami, demonstrated the need for reliable information on the magnitude and recurrence interval of such events. Sediment archives are a major source of data on extreme palaeoenvironmental events. However, de...
Shoreline changing position along the coast is an immediate and long-term indicator determined by the interplaying driving forces across the dry and wet parts of coastal areas. Extreme waves, such as tsunamis, may result in a remarkable shift of shoreline position and a change of sediment transport regime, thus potentially inducing coastal hazards....
