| 摘 要： | 近两年来，关中地区地震活动呈现东部相对活跃而西部平静的局面，打破了近20年来西部相对活跃的格局。从三信方面分析了形成这种格局的原因，认为这是大区域应力调整，汾渭地震带地震逐渐活跃而西海固地区相对平静以及关中地区地壳运动变化的结果，在此基础上对今后关中地区地震活动趋势进行了分析和研究。

| Abstract: | In recent two years, the seismicity in Guanzhong area (the central Shaanxi plain)was relatively active in the east but calm in the west, which broke the near 20 years' regulation that the west is relatively active. Through analysis it is thought that it is the result of large area's stress adjustment, of the influence of the pattern that the earthquakes are gradually active in Fenwei seismic belt but relatively calm in west Haigu, and of the crustal movement in Guanzhong area. Based on this, the seismic activity trend in the Guanzhong area was given. |
