This can be due to a variety of factors, both natural (such as earthquakes, volcanic activity and compaction of fine-grained unconsolidated sediments) and anthropogenic (for example, mining and groundwater abstraction). It poses a major issue in urban zones where it can cause building collapse and damage to infrastructure that may be a hazard to life and a resource management problem. /news/2024-03-billion-people-globally-subsidence.html Earth Sciences Thu, 07 Mar 2024 10:59:42 EST news629031576 Nanodevices can produce energy from evaporating tap or seawater Evaporation is a natural process so ubiquitous that most of us take it for granted.
