The associated volume change of the decarbonation reaction accounts for the continuing subsidence of the Cheb Basin adjacent to themajor focal zone. The local stress perturbation created by the subsidence, in combinationwith the regional stress field, may account for the recurring swarmseismicity. The largest earthquake energy has been continuously released along a steep contact between orthogneisses of the uplifting Krušné Hory/Erzgebirge domain and granites of the subsiding Smrčiny/Fichtelgebirge domain, forming boundary between two lithospheric segments.
