Abstract
Whether the surface rupture of the south segment of Minjiang fault is present remains a controversial issue in recent years. In previous work, interpretation of remote sensing images from Google suggests that this fault section exposes on slopes of the eastern bank of the Mingjiang River, expressing as surface ruptures, implying its activity during Holocene. While the features of fault scarps seen in the field challenges the existence of these ruptures. By virtue of exhaustive field investigations, this paper attempts to further address this issue. Our analysis of geology and geomorphology suggests that the topographic characteristics from remote sensing data are not traces of surface ruptures, instead resulted from a big landslide at the river. Thus it reminds us that there may be a great uncertainty when using remote sensing images interpretation to infer surface ruptures associated with faults.
