Satellite-Detected Earthquake Damage Assessment for Daraudi Valley, Nepal

651 structures affected by the 25 April 2015 earthquake in Nepal's Daraudi Valley were identified via satellite imagery. UNITAR/UNOSAT classified 434 structures as destroyed, 175 severely damaged, and 42 moderately damaged. This preliminary analysis from imagery acquired on 29 April 2015 has not been validated in the field.

Use Cases

• Map earthquake damage intensity based on satellite-detected destruction levels
• Analyze the spatial distribution of affected structures relative to the epicenter
• Support ground validation efforts by providing a preliminary damage assessment
• Estimate infrastructure loss for recovery planning based on the 651 affected structures

Strengths

• Damage assessment is quantified with specific counts: 651 affected, 434 destroyed, 175 severely damaged, 42 moderately damaged
• Analysis is based on satellite imagery acquired shortly after the event on 29 April 2015
• Geographic scope is precisely defined as the Daraudi Valley near the earthquake epicenter

Limitations

• The analysis is preliminary and has not been validated by ground feedback
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
