NASA OPERA Project: Landslide Inventories for High Mountain Asia and Hydropower Risk

High Mountain Asia and the Pumpqu/Arun River basin are covered by landslide inventories from the NASA OPERA Project. The first catalog includes approximately 2800 landslide events recorded between January 2007 and December 2018, with data on triggers, locations, and impacts. This data supplements the NASA Global Landslide Catalog with citizen science reports and was generated in support of a World Bank hydropower project risk assessment.

Use Cases

• Modeling landslide risk to hydropower projects based on event triggers and locations mentioned in the description.
• Analyzing temporal trends in landslide occurrence across High Mountain Asia based on the 2007-2018 date range.
• Assessing the human impact of landslides based on reported injury and fatality counts.
• Mapping landslide susceptibility using geospatial event locations and characteristics like slide length and area.

Strengths

• Catalog of approximately 2800 landslide events provides a substantial sample for analysis.
• Covers a specific 12-year time range from 2007 to 2018, offering temporal consistency.
• Includes multiple event characteristics such as triggers, country, length, area, and casualty counts.
• Publicly available under a CC-BY-4.0 license, facilitating open research and redistribution.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
