A recent study has suggested that palaeo-tsunami events in the South China Sea may have attained wave heights of up to 15 m. One method for investigating palaeo-tsunami along coastlines is the study of boulders that, through measurement and the use of hydrodynamic equations, may assist in understanding wave heights. An area with known high magnitude tsunami is the eastern coast of Moro Gulf on the island of Mindanao (Philippines) in the Celebes Sea, where a damaging tsunami of up to 9 m high occurred in 1976. This study undertakes a reconnaissance of the coastline using Google Earth imagery and, appreciating limitations, identifies two potential coastal sites with presumed wave-transported boulders near Namat and Sedem, c. 10 and 55 km from the 1976 earthquake epicentre respectively. Using Google Earth tools, 12 boulders were measured and, with some estimated parameters, heights calculated for both tsunami and storm waves required to transport the boulders. This preliminary analysis indicates that four of the boulders may have been transported by storm activity, but all 12 boulders could have been transported by the 1976 tsunami. Indeed, the orientation of the majority of boulders indicates a flow direction consistent with the location of the 1976 earthquake epicentre. Furthermore, there is no evidence presented in this preliminary analysis to suggest that a tsunami of a magnitude greater than the 1976 event has affected this coastline. An hypothesis is concluded that could be used to guide future fieldwork in this regionally important area of natural hazard studies. Abstrak: Satu kajian baru-baru ini menunjukkan bahawa peristiwa palaeo-tsunami di Laut China Selatan mungkin telah mencapai ketinggian gelombang sehingga 15 m. Satu kaedah untuk menyiasat palaeo-tsunami di sepanjang garis pantai adalah kajian batu-batan yang, melalui pengukuran dan penggunaan persamaan hidrodinamik, dapat membantu dalam memahami ketinggian gelombang. Kawasan yang pernah dilanda tsunami magnitud yang tinggi adalah pantai timur Teluk Moro di pulau Mindanao (Filipina) di Laut Celebes, di mana tsunami dahsyat setinggi 9 m berlaku pada tahun 1976. Kajian ini melakukan peninjauan garis pantai dengan menggunakan imejan Google Earth dan, peka terhadap ketidakpastian yang wujud, mengenalpasti dua tapak pantai yang berpotensi dengan batu yang berkemungkinan diangkut gelombang berhampiran Namat pada 10 km dan Sedem pada 55 km dari pusat gempa bumi. Dengan menggunakan alat Google Earth, 12 buah batu diukur dan, dengan menganggarkan beberapa parameter, ketinggian dapat dikira untuk kedua-dua gelombang tsunami dan ribut yang diperlukan untuk mengangkut batu tersebut. Analisis pendahuluan ini menunjukkan bahawa empat buah batu mungkin telah diangkut oleh aktiviti ribut, tetapi kesemua 12 buah batu boleh diangkut oleh tsunami tahun 1976. Malah, orientasi majoriti batu menandakan arah aliran yang konsisten dengan lokasi pusat gempa bumi tahun 1976. Selain itu, tiada bukti yang dibentangkan dalam analisis awal ini untuk mencadangkan bahawa tsunami ber...
