We have conducted a temporary observation of earthquake ground motion of aftershocks of the 2023 Kahramanmaras earthquake in southern Turkey in the damaged areas for an acquisition of basic data to understand the earthquake damage. Strong motion accelerometers were installed at 21 stations in Pazarcik, central parts of Kahramanmaras and Adiyaman provinces, Iskenderun and Antakya in Hatay province. One of the stations in each area was selected in a mountain area as a reference station. The characteristics of the observed ground motion are investigated by spectral ratios of the stations to those at the reference stations. The site amplifications are not significantly different in Pazarcik. Most of the site effects in the damaged areas in the other regions are characterized with the large amplifications at frequencies less than 1 or 2 Hz. In particular the site effects are so significant in the damaged areas in Iskenderun, Antakya and Samandag.
