ASTER Level 2 Surface Kinetic Temperature (AST_08) over Kīlauea Crater, Hawaii, acquired on 2025-08-09 at 07:30:32 UTC. The image shows a semi-transparent thermal overlay on an Esri satellite basemap. A concentrated hotspot of temperatures exceeding 100°C is visible near the center of the crater floor, displayed in deep red, surrounded by a gradient of orange and yellow tones indicating elevated but cooler surface temperatures. The surrounding terrain shows ambient temperatures near 0°C. The spatial ex
