Abstract
⺠In the Archean Kuusamo region, the seismogenic layer extends from about 8 km below the surface down to a depth of 30 km. ⺠Apparent aseismicity of the uppermost crust is explained by the excess of strong mafic material. ⺠The maximum depth of earthquakes correlates best with the onset of brittle-ductile transition. ⺠No evidence was found on movements in the lowermost crust.
