Early warning systems

Systems need to be developed to monitor both short-term and long-term geohazards and their effects, and to forewarn of impending danger, in areas where geohazards could affect life and property.

To develop reliable early warning systems, the physical processes and mechanisms need to be understood and methods need to be developed for measuring, modeling, and predicting geohazards, for example, landslides and tsunamis.

Developing early warning systems also require

  • setting criteria for parameters to be monitored and threshold values
  • developing monitoring equipment and systems
  • coordinating satellite radar data with local monitoring stations
  • planning monitoring programs for high-risk areas
  • developing computer-aided decision-making tools with e.g. mobile data mapping and retrieval, and information management using geographical information technology (GIT), Remote sensing (RS), and 3D modeling.
