Ash plume from Barren Island volcano. Image Source: NASA Space Shuttle Date: March 14, 1995
Comments: This oblique shot shows a large eruption plume dispersing westwards towards the main island group. From the photographs, it seems that there are three levels of the eruption plume: the first is low level, near the base of the eruption column and spreading southwest (upper left in this image). The other two levels are higher, with a suggestion of a due westerly plume (right in this image) overlain by a less visibly dense west-southwest plume of slightly different composition (upper right).
Top 20 quakes in 2016: Several magnitude 7 quakes occurred in 2016 (but none above M8): Papua New Guinea, NZ, Ecuador, Solomon Islands, Sumatra, Chile, Alaska and others - nearly all major earthquakes were located near active subduction zones.
See the top 20 list of largest quakes in 2016 with this map.
Krakatoa explodes: In the afternoon of 17 Oct, a particularly violent explosion occurred at Anak Krakatau, blasting away a portion of the southern crater rim. A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec 2018.
