Mauna Kea from Mauna Loa's upper Northeast Rift Zone

A view of Mauna Kea from Mauna Loa's upper Northeast Rift Zone. The haze in the saddle area, between Mauna Loa and Mauna Kea are caused by emissions from Kilauea Volcano. These emissions, known as Vog, are the result of volcanic gasses, primarily sulpher dioxide, mixing with moisture and dust in the atmosphere. Notice that the summits of both mountains are clear of haze, this is due to an inversion layer with an average height of about 6,000 feet, (2,000m). The result is a dry and stable atmosphere above the inversion layer. Photo: USGS

Lava visible within Halemaumau's collapse pit!




Spectacular eruptive activity has been occuring within the collapse pit in Halemaumau crater at Kilauea's summit. In this photo taken by the Hawaii Volcanoes Observatory, a lava stream is clearly visible within the pit. Also visible, are the walls of the pit, which are usually obscured by fumes. This is a great time to visit Kilauea volcano! Make the most of your visit with a tour by Native Guide Hawaii, or send me an email for more information.
