What exactly is subsidence?

Subsidence is the “sinking of the ground because of underground material movement”, according to the National Oceanic and Atmospheric Administration (NOAA). It can happen for a host of reasons, man-made or natural, such as the removal of water, oil, or natural resources, along with mining activities. Earthquakes, soil erosion, and soil compaction are also some of the well-known causes of subsidence.
According to experts, Joshimath city has been built on ancient landslide material — meaning it rests on a deposit of sand and stone, not rock, which doesn’t have a high load-bearing capacity. Moreover, the lack of a proper drainage system could also have contributed to the sinking of the area. The accumulated water seeps into the rocks below, softening them.
