tsunami sediments, we learned the velocities the water must have been moving to
suspend and redeposit those particular sized grains and grain densities. We also used
foraminifera to understand from where the sediments might have originated. The
sediment source (offshore, nearshore, or backshore) could tell us about distance to
source and source water depth, which helps us to infer tsunami wave characteristics
such as velocity and wave height.

Fig. 10.10 Flow depth of 2004 Indian Ocean tsunami in Langkawi, Malaysia. Muddy tsunami
water left the telltale signs of the maximum runup and inundation level. In this image the water
depth is about 3 ft. (1 m) above the floor of the house. (Image by A.D. Hawkes)
