Pico de Fogo Volcanic Eruption Impact Map from Satellite Imagery, November 2014

United Nations Satellite Centre (UNOSAT) produced this geospatial dataset illustrating areas affected by the Pico de Fogo volcanic eruption on Fogo Island, Cape Verde. The map is based on WorldView-2 and LANDSAT-8 satellite imagery from November 24-25, 2014, showing lava flow extent, affected roads, and impacted villages. It includes estimates of affected roadways and lava-covered area, with a note that the analysis was not validated in the field at the time of creation.

Use Cases

• Modeling lava flow progression based on satellite observations from November 24-25, 2014.
• Assessing infrastructure damage based on the reported 8,000 meters of affected roadways.
• Mapping land cover change based on the estimated 150-260 hectares of lava observed.
• Validating remote sensing analysis with ground truth data for disaster response.

Strengths

• Provides specific quantitative estimates: ~8,000 meters of affected roadways and 150-260 hectares of lava observed.
• Uses multi-source satellite imagery from WorldView-2 and LANDSAT-8 for November 24-25, 2014.
• Identifies specific impacted villages: Portela, Cha Das Caldeiras, and Bangaeira.

Limitations

• The description notes the lava flow is likely underestimated due to smoke, and the analysis was not validated in the field.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
