摘要

H-CN; mso-bidi-language: AR-SA" lang=EN-US>Based on the focal mechanism solution database established by collecting 37 years initial motion of small earthquakes (1970~2006), the space-time evolution characteristics of small-earthquake integrated mechanisms in xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Shanxi fault zone are studied in this paper. The results indicate that small-earthquake integrated mechanisms in Shanxi fault zone are mainly dominated by strike slip normal faults, at the two ends dominated by extension tectonics and in the central region by shearing.
