Abstract
The article is devoted to the spatial distribution of the average productivity of earthquakes in the main part of Japan for the period 2000–2020. The maps were generated with The Generic Mapping Tools using the Japan Meteorological Agency catalog for earthquakes 40 km below the surface. We are talking about «crustal» earthquakes on the island part of Japan. Maps were built for the period 2010–2020, where the radius (25 km, 50 km, 100 km), catalog completeness (1 and 1.5) and ∆ -productivity (1 and 2) were varied. For the most indicative map, the stability of the picture in time was checked. An attempt was also made to test the effect of surface heat flux on the distribution of average earthquake productivity.
