Changes in the configuration of Bogoslof Island resulting from the ongoing 2016-17 eruption. The January 30-31, 2017 eruptive activity generated roughly 0.4 square kilometers of new land and as of January 31, 2017, the island area was 1.02 square kilometers, roughly three times the size of the pre-eruption island. Since then the area of the island has declined slightly due to wave erosion and expansion of the shallow seawater lake in the middle of the island. Eruptive activity since January 31 does not appear to have contributed much if any new pyroclastic fall and flow (surge) deposits to the island. If no new eruptive material is added to the island, wave action will begin to gradually erode the outer coastline.
