Some new NASA Earth Observatory Images

A roundup of the latest volcanically-related NASA Earth Observatory images, including Rabaul, Shiveluch and a great panorama of the Canary Islands.

In case you don’t frequent the NASA Earth Observatory, I thought I’d call your attention to some images they recently posted that are, again, excellent shots of volcanism captured from space.


  • The current plume from Tavurvur Crater at Rabaul was shot by the MODIS imager on Terra in early August. The plume is mostly made of volcanic gases and steam, but minor amounts of ash are also found – and remember, even small concentrations of ash in the air can be hazardous to aircraft.
  • Shiveluch has been having a busy summer, with moderate-to-large plinian eruptions produced by the emplacement (and destruction) of a new dome at the summit. This MODIS image (taken from the Aqua satellite) shows both the plume heading out over the Bering Sea and also the the extent of the ash fall on the Peninsula – along with the deposits from pyroclastic flows or lahars (most likely) on the west (left) side of the volcano.
  • The last one isn’t directly related to active volcanism, instead it shows fires that are occurring in the Canary Islands. The Canaries are all volcanic islands in the eastern Atlantic formed by a hotspot under the African plate (similar to what happens at Hawai’i). Each island is made of one to multiple volcanoes, some of which are still active, such as Tiede on Tenerife.

    The NASA Earth Observatory has posted some great new shots of volcanoes from space, including four volcanoes erupting at once and the latest from the Icelandic eruption.
    Bits of volcanic news, including a great image of the eruption at Shiveluch, evacuations related to the earthquakes in Saudi Arabia and the hazards of lake overturn (oh yes, and indie rock).

    Up Next
    Shiveluch continues its noisy summer, we hope to avoid unnecessary noise at Crater Lake National Park and former noise spotted on Mars.
