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