Summary

[edit]
Description
English: This natural-colour satellite image of the summit of Mauna Loa — overlaid with 100-meter contour lines, helps illustrate why volcanic emissions from the summit rarely reach the observatory.
  • The observatory is located on the northern slope of the mountain, 6 kilometres away from and 800 meters lower than the summit.
  • Most of the time, the prevailing north-easterly trade winds prevent volcanically contaminated air from reaching the observatory. Only on a small percentage of nights do the winds become light and southerly, pushing volcanic emissions downhill to the observatory.
