Our report is devoted to the memory of the outstanding Japanese scientist. In 1896, Fusakichi Omori discovered the law of the aftershocks evolution that bears his name. We represent the Omori law in the form of a differential equation. This allows us to take into account the non-stationarity of rocks in the earthquake source, which cools down after the main shock. By using aftershock equation we put the inverse problem of physics of the earthquake source. On this path we hope to find approaches to the diagnostics of the state of rocks in the source and to forecast of the likely evolution of processes leading to a subsequent strong earthquake.
