Krakatoa volcano (Sunda Strait, Indonesia): fresh aerial image showing the island's dramatic change in shape

A fresh aerial image from Anak Krakatau has appeared on the very active Volcanoes and Volcanism group on facebook:
it shows in more detail what the 29 Dec satellite image already confirmed: the island of Anak Krakatau has now the shape of a 270 deg almost closed crescent, with a water-filled crater in the center where once the 330 m tall summit cone stood (which collapsed on 22 Dec causing the tsunami).
Although the image is not detailed enough, it seems (and it would be expected so after the violent phreatomagmatic activity following the collapse) that virtually all of the island has been covered and reshaped, smoothed out by fresh pyroclastic deposits. What if any of its flora and fauna has survived needs to be found out yet by visiting it.
Happy New Year to all!

This processed satellite image from 28 Dec below shows the change in morphology even clearer, but includes a significant land gain after the collapse as well, which seems to have build most of the southern "arm" of the crescent. Most of the new land is probably due to accumulated material (tephra) from the intense sursteyan activity in the days after the landslide, building a new large tuff ring around the crater:

On 17 Oct, explosions were particularly violent at Anak Krakatau. We show a series of images of a spectacular explosion captured from close range by boat. 2 months later, the cone of Anak Krakatau collapsed into the sea on the evening of 22 Dec 2018, triggering a catastrophic tsunami (more info). ...

Saturday, Dec 29, 2018
The activity at the volcano continues at reduced rate. Steam explosions have been more intermittent and smaller during the past 2 days, generating plumes that rose a few hundred meters only. ... [more]
Friday, Dec 28, 2018
After almost 6 days of an almost non-stop ash plume to 55,000ft following the devastating collapse, Darwin VAAC reports that activity has finally subsided with only very minor emissions. No updates about local conditions at the moment. [more]

The violent explosive activity caused by magma-water interaction continues at the volcano, from the area where the summit cone collapsed on 22 Dec and now exposes the vent to sea water. ... [more]
