  • Identification of sources in geohazards
    • Tectonic Activity
    • Human Activities
    • Climate and Weather
    • Geological Features
    • Hydrological Factors
  • Tectonic Activity

    Geohazards such as earthquakes and volcanic eruptions are mainly caused by movement of tectonic plates such as convergent and divergent activities
  • Human Activities
    Anthropogenic activities such as deforestation, urbanization, mining and construction can increase geohazards by changing the natural landscapes
  • Climate and Weather
    • Long-term changes in climate patterns, including temperature, precipitation, and sea level, can influence the frequency and intensity of geohazards
    • Severe weather events such as tornadoes, cyclones, thunderstorms, and heavy rainfall can trigger floods, landslides, and storms
  • Geological Features
    Natural geological features such as cliffs, escarpments, and unstable slopes can pose hazards such as rock falls, landslides, and rockslides
  • Hydrological Factors
    Changes in river flow, coastal erosion, sea-level rise, and tsunamis pose significant hazards to coastal communities, infrastructure, and ecosystems
  • Methods and approaches for identifying sources of geohazards
    • Geological and Geophysical surveys
    • Field investigations
    • Community Engagement
    • Remote Sensing and GIS Analysis
    • Hydrological and Meteorological Monitoring
  • Geological and Geophysical surveys
    Conducting field surveys and geological mapping to identify geological structures, landforms, and features related to potential hazards helps in assessing the susceptibility of an area to geohazards
  • Field investigations
    Conducting field observations and assessments of geological features, landforms and topography help in identifying potential sources of geohazards
  • Community Engagement
    Local knowledge and experiences of the communities are helpful in scientific assessments and help in developing hazard mitigation strategies
  • Remote Sensing and GIS Analysis
    Remote sensing technologies, including satellite imagery, aerial photography, and radar, are used to collect data on land cover, topography, vegetation, and changes in the Earth's surface which helps in identifying potential hazard sources and the mapping of hazard-prone areas
  • Hydrological and Meteorological Monitoring
    Installing weather stations and monitoring weather patterns, temperature variations, river flow, and groundwater levels help in assessing the likelihood of hazards
