importance of source identi....

• Identification of geohazard sources

  Allows for complete risk assessments to understand the potential impacts of hazards on communities, infrastructure, and the environment
• Identification of geohazard sources

  Enables the development of effective mitigation strategies and land-use planning measures to minimize vulnerability and reduce the risk of disasters
• Identification of geohazard sources


  Helps in the design and implementation of early warning systems to provide timely alerts and evacuation plans for at-risk areas
• Understanding geohazard sources


  Helps communities to adopt measures, including disaster preparedness, infrastructure improvements, and sustainable development practices
• Natural Variability


  • Geohazards are influenced by natural processes that fluctuate or change over time and space
  • Uncertainties arise due to fluctuations in geological, meteorological, and environmental conditions
  • Examples include variations in rainfall patterns, seismic activity, and erosion rates
• Data Uncertainty


  • Geohazard assessment depends on data collected from different sources, such as remote sensing, monitoring networks, and geological surveys
  • Uncertainties in data quality, accuracy, and completeness can affect hazard mapping, modeling, and prediction
• Model Uncertainty


  • Geohazard models are used to observe and predict the behavior of hazard processes
  • Model uncertainties result from simplifications, assumptions, and parameterizations used in model development
• Temporal Uncertainty


  • Geohazards show temporal uncertainty, with hazard events occurring over different time scales, ranging from minutes to years
  • Uncertainties arise from predicting the timing, frequency, and magnitude of future hazard events
• Spatial Uncertainty


  • Geohazards show spatial variability, with hazard events occurring in specific locations and affecting different geographical areas which makes it difficult to predict an event
• Decision-Making Uncertainty


  • Decision-making uncertainty arises when there is doubt about which hazard mitigation strategies or policies to choose and how to implement them
  • This uncertainty involves not being sure about what stakeholders want, how much the chosen strategies will cost, and which goals to prioritize
  • It can impact how well risk management measures work and whether people accept them
