Pu‘u ‘Ō‘ō thermal camera viewing geometry

 

Pu‘u ‘Ō‘ō thermal camera viewing geometry...
Views into Pu‘u ‘Ō‘ō's current crater are often hampered by fume. To overcome this, HVO uses thermal cameras that detect heat and are better able to 'see' through the fume. This image mosaic compares the Pu‘u ‘Ō‘ō thermal webcamera's view with an oblique aerial photograph to show what the thermal camera is looking at. The thermal webcamera is looking approximately toward the east and commonly shows several hot spots, which are outgassing vents. Three such hot vents were in view of the thermal camera on July 19, the date that the thermal camera captured the image on the left. The arrowed letters show how those vents match up between the thermal image and the aerial photograph. The thermal camera does not have a view of a pit which formed west of the current crater in late March and which contains a small lava pond.
