Changes in shoreline location of Bogoslof Island due to explosive eruptive events of Bogoslof volcano in late December 2016 as determined by analysis of Worldview satellite images. The pre-eruption shoreline as seen in an image from July 29, 2011 is shown as a red line. The location of the shoreline from December 22 and 25 are shown in cyan and magenta, respectively. The vent for the eruption is presumably located underwater, just off the northeast portion of the main island. Explosive eruptions were detected in monitoring data on December 20, 21 and 23, 2016
