The detailed sedimentological properties of tsunami
deposits are presented elsewhere [24]; here, we only report
the major characteristics. Sedimentary deposits from the
tsunami were found in most places where tsunami flooding
occurred. The thickness of most of the deposits was mainly
from 5 to 20cm. The studied samples belong to a wide textural
range, from coarse silt to coarse sand, with very fine
to medium sand being the most common. These deposits
are usually poorly to moderately sorted and from very fine
to very coarsely skewed. The studied pre-tsunami soils are
composed mostly of moderately well-sorted fine to medium
sand, and the beach sediments from poorly to moderately
sorted medium to coarse sand.
