Information from satellite imagery helped to differentiate areas vulnerable to soil erosion from off-highway vehicle use. For this study we developed a “P-factor” by scaling ground measurements of soil compaction to vehicle disturbances mapped from aerial imagery.

During today's overflight of Kīlauea summit, both thermal and visual cameras were used to characterize activity. Comparing thermal (left) to visual (right) images of nearly the same view, you can see that the growing crater lake at Kīlauea's summit remains hot.
