Damage reports and geological effects from a magnitude 6.3 earthquake near Westmorland and Calipatria, California. The event caused an estimated $1-$3 million in damage, including road subsidence, liquefaction features, and broken irrigation canals. Data was recorded by NOAA's National Centers for Environmental Information following the event on April 26, 1981.
Use Cases
- Classify earthquake damage types (e.g., road collapse, liquefaction mudpots) from event descriptions.
- Estimate financial impact of seismic events on agricultural regions using reported damage costs.
- Map locations of soil liquefaction and subsidence for geological hazard modeling.
- Analyze vulnerability of concrete-lined irrigation canals to seismic ground motion.
Strengths
- Records a specific, significant seismic event with a magnitude of 6.3.
- Includes concrete damage estimates in the range of $1-$3 million.
- Documents multiple specific damage phenomena (subsidence, liquefaction, canal breaks).
Limitations
- Data scope is limited to a single event on a single day.
- Sample size is inherently small, covering one geographical area.
- Lacks quantitative measurements for most described damage features.
