The devastating impact of the floods in Nepal is clearly visible in satellite images. The destructive path continues westwards along the swollen river, before heading southwards. The satellite imagery also shows the formation of a barrier lake at the base of the landslide's path, which Chinese authorities have warned poses a major risk of further flooding and has hampered rescue efforts.
Dr Argha Banerjee, a glaciologist at the Indian Institute of Science Education and Research, told BBC Verify that it was not possible to determine from the images how stable the barrier was or how likely the lake was to drain suddenly. However, he noted that there was no significant increase in its surface area between Wednesday and Thursday, despite water continuing to flow into the lake.
Dr Banerjee said there was a visible drainage channel, which suggests some water was already escaping downstream, adding that the lake's volume was "not alarmingly large" and appeared to have stabilised.
The extent of the damage on the Tibetan side of the border remains unclear. It is a strictly controlled region which China annexed in the 1950s, where foreign media access is heavily restricted. BBC Verify has so far been unable to find verifiable footage from the area.
The satellite imagery - which only provides an initial glimpse into the damage of the flood - has been published by Vantor as part of its Open Data Program to help aid authorities establish where best to focus their efforts to locate the missing, rescue survivors and recover the dead.
