Geohazard Model Parameters


  • Surficial Geology

    Surficial geology maps carry information about surficial deposit genesis, material, texture, thickness, geomorphic form, and geomorphic process.


    Surficial geology studies have a broad range of application, including land planning, slope stability assessment for logging operation, aggregate potential and mineral deposit exploration and earthquake hazard characterization. 


    Surficial geology characterization of each target assisted The MMI® system to more accurately rank polygons according to their landslide type affinities.

  • Bedrock Lithology

    Bedrock lithology is an important component in landslide susceptibility map: highly foliated metamorphic rocks constitue weaker rock masses than vertically, broadly spaced jointed granites. 


    Reasoning about the distribution of different lithologies allowed to identify the location of different landslide types.


    Large volcanic debris avalanches can be generated only from the Quaternary volcanoes in the area (Mount Garibaldi, Mt Cayley), while smaller rockfalls in basement rocks are common along the Sea to Sky highway.


    Lithology terms were aligned to GeoSCIML terminology to allow reasoning at a global scale.

  • Slope

    Slope gradient in degree was calculated for the area of interest.

  • Precipitation & Watershed

    Intense rainfall can trigger landslides. Water infiltrating rocks an sediments can increase pore water pressure and cause slope to fail and sediments to mobilize. When landslides hit steams or when water saturated debris start to move down a creek, a debris flow is generated. To map debris flow susceptibility we extracted the channel distribution from the digital elevation model (DEM) and considered one rainstorm event to highlight the channels that are more likely to generate a debris flow. 


    The MMI® system can identify the creeks that have higher precipitation and are more likely to have landslides in the given rainstorm event.

  • Permafrost & Ice

    Permafrost degradation and glacier retreat have an important role in rock slope stability.


    The MMI® system is able to reason about rock properties and permafrost distribution to highlight the slope that may generate permafrost degradation related landslides.

The Minerva Machine Intelligence® (MMI) system


The Minerva Machine Intelligence® system records the type of match recognized between each pair of landslide models and map polygons attributes.

This assists the reader of the report to understand the MMI® system’s reasoning, and it allows the MMI® system to adjust its similarity scores according to the strength or weakness of the match.
