When soil behaves like a liquid it can lose its ability to support structures. The soil can even flow down very gentle slopes, and erupt to the ground surface to form sand boils (“sand volcanoes”).

The DESIS and PRISMA Derived Spectral Library of Agricultural Crops in California was developed using 2020 DESIS and PRISMA data for almonds, corn, cotton, grapes, pistachios, rice, and tomatoes. For more details, see “New Generation Hyperspectral Sensors DESIS and PRISMA Provide Improved Agricultural Crop Classifications” (DOI: 10.14358/PERS.22-00039R2)
