Horizontal deformation in Fentale caldera associated with the 14 February 2025 earthquake from Planet satellite imagery

This dataset describes the deformation that affected Fentale volcano caldera, coeval to the occurrence of a M=6 earthquake on 14 February 2025 (20:28 UTC), located below the volcano.

Deformation was computed by sub-pixel correlation of Planet orthoimages acquired on 7 and 16 February 2025. Products were ordered at "surface radiance" processing level. Correlation was performed on band 8 (NIR) using the MicMac software (Rosu et al., 2015).

A preview of the result is included in this dataset (MicMac_correlation_results_Fentale_2025-02-14_preview.png).

The dataset includes a GeoTiff (MicMac_correlation_results_Fentale_2025-02-14.tif) consisting of 5 bands:
- the orthoimage of 7 February (band 8)
- the orthoimage of 16 February (band 8)
- the correlation score (between 0 and 1)
- the estimated E-W component of displacement (in meters, positive towards the east)
- the estimated N-S component of displacement (in meters, positive towards the north).

Details of the MicMac calculation procedure are given in a text file (README.txt).

Parameters of the MicMac calculation are provided in MicMac_correlation_parameters.xml.

Metadata of the two original Planet products are also included in the dataset (20250207_080600_27_24cb_3B_AnalyticMS_8b_metadata_clip.xml and 20250216_080609_04_250d_3B_AnalyticMS_8b_metadata_clip.xml).
