[[File:Main india night Jan 06-21-28 01.gif|thumb|The thermal night recording on January 6, 21 and 28, 2001 in the Gujarat region of India. Marked with an asterisk is the epicenter of the Bhuj earthquake on January 26 that was of 7.9 magnitude. The intermediate recording reveals a thermal anomaly on January 21 which is shown in red. In the next recording, 2 days after the earthquake, the thermal anomaly has disappeared.]]
One way of detecting the mobility of tectonic stresses is to detect locally elevated [[temperature]]s on the surface of the crust measured by [[satellite]]s. During the evaluation process, the background of daily variation and [[noise]] due to atmospheric disturbances and human activities are removed before visualizing the concentration of trends in the wider area of a fault. This method has been experimentally applied since 1995.<ref>{{Harvnb|Filizzola|Pergola|Pietrapertosa|Tramutoli|2004}}.</ref><ref>{{Harvnb|Lisi|Filizzola|Genzano|Grimaldi|2010}}.</ref><ref>{{Harvnb|Pergola|Aliano|Coviello|Filizzola|2010}}.</ref><ref>{{Harvnb|Genzano|Aliano|Corrado|Filizzola|2009}}.</ref>

In a newer approach to explain the phenomenon, [[NASA]]'s Friedmann Freund has proposed that the [[Infrared|infrared radiation]] captured by the satellites is not due to a real increase in the surface temperature of the crust. According to this version the emission is a result of the quantum excitation that occurs at the chemical re-bonding of [[Electric charge|positive charge]] carriers ([[Electron hole|holes]]) which are traveling from the deepest layers to the surface of the crust at a speed of 200 meters per second. The electric charge arises as a result of increasing tectonic stresses as the time of the earthquake approaches. This emission extends superficially up to 500 x 500 square kilometers for very large events and stops almost immediately after the earthquake.<ref>{{Harvnb|Freund|2010}}.</ref>
