**6. Conclusion**

This preliminary research about lava flows erupted from YS and DHG tries to bring a new insightful result of lava evolutionary histories and subsequent hazard evaluations. Sentinel imagery plays an essential role in this research. Calculations for the lava volumes and effusion rates are the major outcomes of this research for the first time providing geologically validated and modeled lava flow eruptive volumes for ACVF. GIS-based techniques provided new information on the nature and extent of lava flow inundation. Applying STRM, ALOS-PALSAR Digital Elevation Models and applying GIS techniques to analyze the morphological assets of the ACVF provided a complex framework to simulate lava flow inundation. Lava flow simulations in concert with direct field observations revealed that future lava flow effusion would generate significant lava flow infill along the NE-SW trending valley within Dahei Gou and Yanshan volcanoes sit. As these lava flow likely would reach the main transport routes of the region, complex volcanic hazard studies and probabilistic estimates are needed to mitigate future volcanic hazards. Future research is needed to concentrate on the chronologies of lava successions, and predictions of future eruptions along with the local fissures which formed the lava flows in ACVF.
