Earthquake occurrence in different plate tectonic settings: There are three main plate tectonic environments: extensional, transform, and compressional. Plate boundaries in different localities are subject to different inter-plate stresses, producing these three types of earthquakes. Each type has its own special hazards.
Hydrology, therefore, is a broad science that utilizes information from a wide range of other sciences and integrates them to quantify the movement of water. The fundamental tools of hydrology are based in supporting scientific techniques that originated in mathematics, physics, engineering, chemistry, geology, and biology.
For the historic approach to water cure in Europe, see Water cure (therapy) . For a method of torture involving water, see Water cure (torture) . For the measure of how hydrophobic a molecule is in chemistry, see Hydropathy index. Hydrotherapy, formerly called hydropathy, is a part of medicine and alternative medicine, in particular of naturopathy, occupational therapy and physiotherapy, that involves the use of water for pain relief and treatment.
