“…After the tsunami wave weakens, the seawater returns to the sea at a slow speed so that the sand material carried away will be left behind and settle on the land, this deposit is called a tsunami deposit. Tsunami deposits are used to identify tsunamis in the past (paleotsunami) [8]. Physically, the speed of ocean waves can affect the size of grains carried by a tsunami and how far deposits can form on land.…”

This study is conducted to identify prehistoric tsunami deposit (paleotsunami) in Seubadeh village, located in South Aceh Regency, Aceh province, Indonesia. Regional morphologic and seismic characteristics suggest that Seubadeh village is an area that stores tsunami deposits, both new tsunami deposits and prehistoric tsunami deposits. Therefore, in this study, the search for paleotsunami deposits was carried out in Seubadeh village. The tsunami deposit samples were taken at several points in Seubadeh village using a hand drill with a depth of more than 2 m. Sediment classification of the collected samples using Troels-Smith method shows a candidate layer of paleotsunami tsunami deposit was found between two clay deposits. The layer is dominated by plant roots and shell material. In addition, the sediment samples were sieved using a mesh to evaluate the grain size distribution of clay, silt and sand. The results of the grain size distribution and color evaluation of the respective layer are presented. The results of the analysis of the particle size distribution in the sample and the color of the sample indicate that there are 2 layers that show characteristics as a paleotsunami deposit, namely at a depth of about 170-200 cm and 280-292 cm. The paleotsunami deposit found will be further characterized by an emission spectroscopic technique.

“…LIBS has demonstrated exceptional sensitivity in discerning abundant elements within natural material samples, particularly minerals, rocks, soils, and sediments-a formidable task for many commonly employed analytical methods [8][9]. Previous studies have successfully applied the LIBS technique for elemental analysis of soil affected by tsunamis and for the differentiation of heavy metal contaminants in liquid milk [10][11][12]. This study aims to identify geochemical markers in deposits from the 2004 Indian Ocean tsunami, collected from the coastal region of Aceh Besar Regency, Aceh Province, Indonesia.…”

We undertook an extensive analysis to examine the geochemical imprints encapsulated within the samples of the 2004 Indian Ocean tsunami deposits procured from the Seungko Mulat coastal region, nestled in the western section of Aceh Besar Regency, Aceh Province, Indonesia. In order to induce the formation of micro-plasma, a Transversely Excited Atmospheric Carbon Dioxide-Laser Induced Breakdown Spectroscopy (TEA CO2-LIBS) has been employed as the excitation source. Our investigation unveils distinct spectral signatures within every layer of the stratified tsunami deposit. We observed the unmistakable presence of salt elements (Ca, K, Mg, Na, Al), transition metals, heavy metals (Si, Fe, Ti, Ba, Sr, Cu, Cr, Pb, Mn, Ni, V), and also organic constituents (C, H, O, and N). The emission intensities of these elements exhibited a significant increase within the layers of the tsunami deposit, unequivocally setting them apart from their non-tsunami equivalents. In addition, we performed a vertical analysis of LIBS elemental emission intensity ratios, unveiling unique values for the Ca/Ti, and Si/Ti, ratios, which significantly distinguish them from all other ratios scrutinized in this exhaustive investigation. This research serves to highlight the effectiveness of TEA-LIBS as a promising and efficient optical technique for discerning the chemical profile associated with the renowned 2004 Indian Ocean tsunami deposits from Seungko Mulat Village in Aceh Province.

“…In forthcoming research, we intend to use the LIBS method to perform geochemical analysis of the tsunami sediment samples. We have already employed the LIBS approach successfully in identifying chemical markers for soil samples that were impacted by the 2004 tsunami in Aceh Province, and we have discovered promising chemical markers that can distinguish between soils affected by tsunamis and those that are not [6].…”

Identification of the tsunami candidate layers deposited by the Indian Ocean tsunami in 2004 has been successfully performed in Pulot Village, located in Leupung district, Aceh Besar Regency, Aceh Province. Based on a study of tectonic activity before and after the earthquake, Pulot Village was reported as one of the potential locations for finding tsunami deposits. Tsunami sediment is collected by inserting a hand drill into the ground more than 1 m deep. The presence of the 2004 tsunami candidate layers was identified according to the Troels-Smith characteristics. Based on our visual analysis, the prospective tsunami layer is found at a depth of 4 cm with a thickness of 8-38 cm, which is characterized by fine-medium sized dark brown sand deposits on weathered paleo soil layers. The sharp boundaries with the layers above and below it and the presence of organic material (plant roots, stems and anthropogenic material) can also be clearly observed in the tsunami deposit layers. The candidate layer for the 2004 tsunami deposit found will be further studied geochemically using a laser-induced breakdown spectroscopy (LIBS) instrument.
