This year marks the 150th birthday anniversary of the outstanding seismologist Fusakichi Omori. Our paper is devoted to this significant event. We found that the well-known Omori law may be represented in the form of a differential equation describing the evolution of aftershocks. This allows us to formulate the inverse problem of physics of the earthquake source which is “cooling down” after the main shock. The paper gives the examples of solving the inverse problem and illustrates a possibility to create the atlas of aftershocks after a series of strong earthquakes. The atlas contains a description of the parameters, the original sequence of aftershocks, and the so-called deactivation function for each event. The analysis of the atlas showed a rich variety of the evolution forms of the earthquake source after the main shock.
