The namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Wudalianchi National Park is located in Heilongjiang Province, northeastern China, where the volcanoes are the best examples of the intra-continental monogenetic volcanoes in the world.  The research work shown in this paper is done to study the correlativity between distribution of the intra-continental monogenetic volcanoes in Wudalianchiare and the local fractures. Seismic data, stress state in geological history, as well as study on river terraces, all demonstrate that there were no active fractures taking place during volcanic eruption period in the area. Cusequently, the fractures should exist prior to the volcanic activities in Wudalianchi area. At the times of volcanic eruptions, the faults provided pathways for the underground magmas to migrate upward towards surface, and finally led to forming this kind of volcano distribution seen nowadays on ground surface in Wudalianchi area. namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
