Abstract
There is described a technique for determining a temperature at a region below the surface of the Earth. In an embodiment, a time of travel of a seismic wave following the emission from a source into the earth is provided, and the travel time is used to estimate the temperature. In one example, a model based on the travel time and a further component, which may for example be based on heat flow and a constant of proportionality between seismic velocity and thermal conductivity, may be used to estimate the temperature.
