Caption:March 21, 2017 WorldView satellite image of Bogoslof Island. It is difficult to identify deposits associated with the most recent eruption on March 13 in this image and most of the surficial features evident are erosional. Rill erosion has begun to modify the southern part of the island and it is possible that deeper gullies will form if no new deposits are emplaced during future eruptive events.

Caption:Comparison of Bogoslof Island before the 2016-17 eruption to March 11, 2017 configuration. As of March 7-8, 2017, there have been 36 eruptive events since Dec. 12, 2016. Main geographic points of reference are labelled in each image and point A is the same in both images. Image data provided under Digital Globe NextView License.

Caption:Worldview-2 satellite image of Bogoslof volcano collected on March 11, 2017 at 22:15 UTC (1:15 PM AKST). Eruptive activity on March 8 produced large changes in the shape and size of the island. The most active vent for the explosive activity is located under the water in the center of the island, and it was greatly enlarged by the March 8 event. The western coastline has grown, and a new vent was produced on the north shore of the island. Image data provided under Digital Globe NextView License.

Caption:Worldview satellite images of Bogoslof volcano collected on March 3 and March 11, 2017 showing changes to the island due to eruptive activity on March 8, 2017. The central lake that is the site of the underwater vent is greatly expanded, deposition of volcanic ash and blocks has expanded the island's west shoreline, and a new small vent was formed on the north shore of the island.

Caption:March 11, 2017 Worldview-2 satellite image of Bogoslof Island showing features and changes resulting from the March 7-8 eruption. A new vent developed on the northwest shore of the island adjacent to the lava dome that formed during the 1992 eruption. Most of the deposits on the surface appear fine grained and were likely emplaced by pyroclastic base surges. The surface of these deposits exhibit ripples, dunes and ballistic impact craters. The scalloped appearing shoreline of the intra-island lake is probably the result of groundwater related erosion (sapping) of the pyroclastic deposits as water refills the lake. Most or all of the water in the lake was likely expelled by the eruption column exiting the primary or other vents. The area of Bogoslof Island in this image is about 0.98 square kilometers.
