A group of maps showing the relative susceptibility of hill slopes to rainfall-triggered soil slip-debris flow initiation sites in southwestern California. The maps were created empirically through an iterative process using inventory maps of past events and 10-meter Digital Elevation Models. This dataset was produced by CEOS_EXTRA and sourced from NASA Earth Data.
Use Cases
- Assessing relative landslide initiation susceptibility based on bedrock formation and slope characteristics.
- Modeling soil slip-debris flow hazard zones using empirically derived physical attributes.
- Integrating susceptibility maps with rainfall data for dynamic hazard prediction.
- Validating landslide models using multiple inventory datasets as described.
Strengths
- Based on multiple inventory maps from six rainy seasons that produced abundant soil slips.
- Uses high-resolution 10-meter Digital Elevation Model cells for slope and aspect analysis.
- Maps can be transferred to a 1:24,000-scale base without loss of accuracy.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
