Shoreline changes at Bogoslof volcano
Analysis of shoreline changes at Bogoslof volcano due to eruptive activity between January 11 and 24, 2017. The base image is a Worldview-2 satellite image collected on January 24, 2017. The approximate location of the shoreline on January 11, 2017 is shown by the dashed orange line.

Annotated photo of Bogoslof Island showing effects of eruption
Annotated photo of Bogoslof Island showing effects of eruptionAnnotated photograph of Bogoslof Island showing the cumulative effects of 2016-17 eruptive activity. A layer of fine muddy appearing ash drapes most of the landscape and covers pre-existing vegetation. The dashed line indicates the area excavated by explosive eruptive activity so far.

Rock thin section: andesite
Photomicrograph of sample 09RDWES301 - an andesite collected during the Redoubt 2009 eruption. A rock thin section is created by gluing a small piece of rock onto a glass slide, then grinding it down to a thickness of 30 microns (the average human hair is about 100 microns in diameter) so that light shines through it when examined under the microscope.
