🔎 Analysis & Implication

  • Domination of hydrometeorology
    The data shows that the wet disaster (flood, landslide, wind) is dominant in 2025. Most of the disasters are these kind. It strengthens the trend that extreme weather phenomena become the main trigger of disaster in Indonesia.
  • The increase in risk in monsoon
    Because the rainy season increases the frequency of events, the flood-prone areas and the avalanche needs to be amplified. There is a higher potential toplevel if extreme rainfall continues.
  • Social Load
    The number of people affected in some period (for example August and May), which suggests that social impacts are not only about physical damage, but also about mass refugees and long-term recovery.
  • Advanced Mitigation Required
    This statistic strengthens the argument that the disaster response alone is insufficient: it needs structural mitigation (for example: drainage, flood-resistant infrastructure), early warning system, and education to be more resistant to hydrometeorological risk.
  • Cross Sector collaboration
    Because of the scale of major disasters and spread across many areas, collaboration between BNPB, BPBD, local government and local communities is very important. Moreover, the use of technology (for example weather modification, warning system) could be part of a mitigation strategy.
