6.4 Impacts of the Tsunami

The Nua village and the Andaman Coastal Research Station for Development is
located along the Praphat beach, less than 200 m from the shoreline with low eleva-
tion (1-5 m). Therefore the damage was considerably much more than those of the
Hat Sai Khao village which was located further inland along the distributary chan-
nel, the Kamphuan canal, about 900 m away from the beach with low elevation as
well (Fig. 6.2 ). The tsunami wave height was reported to be about 6 m at the Praphat
beach, which destroyed a large portion of the ACRSD and most of the Nua village.
Part of the Hat Sai Khao village was damaged by the tsunami coming from both
the beach through the low land and along the Kamphuan canal. According to the
witness (August, 2013) at Hat Sai Khao village, the maximum wave height at this
location was about 4 m. In addition to the inundation of the low area along the dis-
tributary channel, the western part of the mangrove fl at land along the Kamphuan
canal and the further inland part of the Hat Sai Khao village were also partly fl ooded
