Yosemite National Park Rock Fall Inventory from 1857 to 2011

925 documented rock fall and landslide events spanning the period 1857 to 2011. This inventory database was created for Yosemite National Park, California, detailing event characteristics and impacts. The data is accompanied by a report describing the database structure and event narratives.

Use Cases

• Analyze probable_trigger and environmental_conditions to identify common causes of slope movement.
• Model magnitude-frequency relations using event date and volume data over the 154-year period.
• Assess hazard by correlating event_location and impact_to_human data with park visitor congregation areas.
• Study temporal trends in relative_size and type_of_slope_movement for susceptibility mapping.

Strengths

• Documents 925 specific events over a long 154-year observational period (1857-2011).
• Includes detailed categories such as impact to humans, volume, and narrative descriptions.

Limitations

• Event detection and reporting likely improved over time, introducing a temporal completeness bias.
• Geographic scope is limited to Yosemite National Park, limiting generalizability.
