Microfracturing and rock deformation as effects of tectonic stress generates sounds called acoustic emission. Many reporting on the earthquakes say that first people hear a noise and then they feel the two shocks (P and S waves). How is this possible as long as the speed of sound is less than the P wave speed? This article gives an answer for these question. An earthquake is an effect of high tectonic stress in an area (hypocenter) and the last part of this process is the loss of elasticity of rocks followed by br...

A thermocline is a layer of water in which a vertical temperature gradient is observed. On freshwater lakes, it is caused by seasonal warming of the surface layer. In the absence of wind mixing, the upper water layer is heated relatively uniformly, the temperature in the lower layer does not change. The temperature transition between the surface and bottom layers creates a thermocline. Since a change in water temperature leads to a change in its electrical conductivity and dielectric constant, a thermocline can be...
