The red stripes seen in the satellite image are roads. And the blue colored background is the drainage system under Joshimath city. There is a possibility of big loss. In the pictures, the central part of Joshimath i.e. the center of the city is marked with a red circle, which shows that this part is most affected by the landslide. The upper part of this depression is present on Joshimath Auli Road. Auli Road is also about to collapse. (ISRO Photo)
