• Spatial Distribution of Tsunami Deposits and Behavior of the Tsunami Flow in the Nam Khem Coastal Plain, Southern Thailand

抄録

Distribution and spatial characteristics of the tsunami flow and tsunami deposits in relation to the landforms of the Nam Khem Plain, Thailand are studied. Landforms of the Nam Khem Plain are characterized by rows of beach ridges and mounds of tin mining dump. Areas with thick tsunami deposits are distributed widely in the northern part of the plain. Direction of up tsunami flow is almost vertical to the coast line, and that of down flow relates to the topography of the area. Up flows of tsunami attacked the area from the two directions from west and northwest, and they concentrated in the northern part of the plain. Several back flows flew from the southern direction and concentrated to the northern part of the plain. These flows caused the accumulation of tsunami sediments especially in the northern part of the Nam Khem Plain. Micro landforms of the plain relate to the distribution of the thickness of tsunami deposits. Existence of the swales between beach ridges corresponds well with the distribution of the thick tsunami deposits.
