In his recent tweet from the International Space Station as it's current Mission 56 Commander, NASA astronaut Andrew J. Feustel says:
This is #Indonesia as viewed from the @Space_Station. With the low clouds it is easy to see the peaks of the volcanoes associated with the Sunda Megathrust subduction zone that lies at the tectonic boundary of the Indo-Australian and Eurasian plates.
I can't visualize where these are on Earth, mostly because of the cloud cover in the image. Where is this?
