- •
We propose a new model of origin of earthquake swarms in the Western Bohemian Massif.
- •
CO2 degassing of the metasomatized mantle may cause the Cheb Basin subsidence.
- •
The subsidence and the regional stress field may account for the seismicity.
- •
Swarms concentrate at a boundary between two lithospheric segments of different age.
- •
The largest earthquake energy has been released at a granite–orthogneiss contact.
