From: Numerical simulations to account for boulder movements on Lanyu Island, Taiwan: tsunami or storm?
Result of the numerical simulation at Langdao (LD). (A) Location of boulders at LD (base map is from Google Earth). The bold arrow shows the boulder which is the maximum in this area. The thin line arrow shows the direction of the survey line. (B) Photograph of a boulder. Radiocarbon dating was performed on this coral boulder. (C) Topographic profile. Boulder size is classified by length of the long axis. (D) Maximum flow depth. The circles and triangles show the a-axis length of boulders. (E) Maximum flow velocity. The circles and triangles denote the flow velocity (rolling) of boulders. The dot-dashed lines in (D) and (E) show the maximum flow depth and maximum flow velocity, respectively, caused by the tsunami (Hsu et al. 2012).
