Satellite Imagery Reveals Devastation

Before-and-after images show how the floodwaters swept through the valley, destroying homes and infrastructure. Damage and mud can be seen more than 2.5km upstream, reaching 100m above the area it first hit.

Satellite imagery also shows the formation of a barrier lake at the base of the landslide's path, which Chinese authorities have cautioned poses a major risk of further flooding and has hampered rescue efforts. A glaciologist from the Indian Institute of Science Education and Research said it was not possible to determine how stable the barrier was or how likely it was to drain suddenly.

Rescue efforts are ongoing, with hundreds of people still missing. Satellite imagery has provided a clearer view of the disaster's origins at the collapsed glacier, which has been captured on verified drone videos.
