Abstract: Using the 25 focal mechanism solutions and receft small shocks data in Liaocheag-Lan-kao fault zone and adjacent area,the basic characteristics of the recent crust stress field and seismicity in the region have been analvscd.11 ba been found that the directions of the compressive and tensile principal stress axes in the region are MEE (≈EW) and NNW (≈SN) respectively, basically consistent with that of North China stress field, and quite agree with that of tbe focal stress field of the Heze earthquake in 1973, But there are some difference in stability of direction of the principal stress axes in sub areas and in seismicity (time-space characteristics etc.).
