Worldview true color satellite image of Bogoslof volcano collected on August 8, 2017, a day after a 3-hour-long explosive eruption. Ash fall deposits have greatly expanded the island towards the north as the result of the eruption and forming a crater lake. Note that at the time of this satellite overpass, the level of the crater lake is below sea level. Previous events such as these (that formed a shallow crater lake) formed a deep crater that was subsequently filled by the influx of ocean water. Vigorous steaming is observed from the likely site of the initial explosive event in mid-December 2016. Sediment coming from erosion of the island is seen in the ocean.
