Summary

This natural-colour <a href="//commons.wikimedia.org/w/index.php?title=Satellite&action=edit&redlink=1" class="new" title="Satellite (page does not exist)">satellite</a> image of the summit of <a href="//commons.wikimedia.org/wiki/Category:Mauna_Loa" title="Category:Mauna Loa">Mauna Loa</a> — overlaid with 100-meter <a href="//commons.wikimedia.org/wiki/Category:Contour_lines" title="Category:Contour lines">contour lines</a>, helps illustrate why volcanic emissions from the summit rarely reach the <a href="//commons.wikimedia.org/wiki/Category:Observatories" title="Category:Observatories">observatory</a>.

  • 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 <a href="//commons.wikimedia.org/wiki/Category:Air" title="Category:Air">air</a> from reaching the observatory. Only on a small percentage of <a href="//commons.wikimedia.org/wiki/Category:Night" title="Category:Night">nights</a> do the winds become light and southerly, pushing volcanic emissions downhill to the observatory.
