From: Numerical simulations to account for boulder movements on Lanyu Island, Taiwan: tsunami or storm?
Result of the numerical simulation at Hongtou (HT). (A) Location of boulders at HT (base map is from Google Earth). The dashed line shows the inundation line. The arrow shows the boulder moved by the typhoon Tembin. The solid circle shows the boulder moved by the typhoon Tembin. (B) Photograph of a boulder. The white arrow shows the grass that appeared to be growing downwards. (C) Topographic profile. Boulder size is classified by length of the long axis. The gray and solid arrows denote the computed and observed inundation limits by the typhoon Tembin, respectively. The open arrows show the computed inundation limits by waves with a return period of 50 years. (D) Maximum flow depth. The circles and triangles show the a-axis length of boulders. (E) Maximum flow velocity. The circles and triangles show the flow velocity of boulders (rolling). The bold lines in (D) and (E) show the maximum flow depth and maximum flow velocity by the typhoon Tembin. The dot-dashed lines in (D) and (E) show the maximum flow depth and maximum flow velocity, respectively, from the fault model of Hsu et al. (2012).
