The Italian satellite constellation with “radar” eyes has observed the explosive activities of the Bogoslof volcano in the Bering sea. The images show the morphological changes to the small island caused by the eruptions

An island in the Aleutian archipelago in Alaska has undergone profound morphological changes caused by the violent eruptions affecting the island's volcano since December.
The Bogoslof couple, composed of the “transforming” island and its volcano, have been under observation by ASI's COSMO-SkyMed satellite constellation: the set of X-band satellites has been focussing on the underwater volcano which has been the protagonist of a series of particularly intense explosions since 12 December 2016, causing a radical change to the appearance of the island - previously a parallelepiped, it is now more or less circular.
As well as creating this drastic morphological mutation, the eruptions also affected regional air transport at the end of January, with clouds of lava dust obstructing the visibility of the rare planes that fly over the area.
