The characteristics of submarine landslide sediments in Eastern Indonesia with study case in Kai Archipelago Waters and Surrounding Area

[摘要] We review the characteristics of submarine landslide sediments as this phenomenon was observed during geological and geophysics systematic mapping in Eastern Indonesia especially surrounding Kai Archipelago using Geomarin 3 owned by the Ministry of Energy and Mineral Resources and operated by the Marine Geological Institute of Indonesia (MGI). In this survey was encountered seafloor sediment characteristics interpreted as submarine landslide products of a seismically active area. The landslide sediments were characterized by mixed up of gravel, sand, silt and clay fractions with percentages between 5.91 - 15.85, 60.1 - 72.68, 9.42 - 22.40 and 4.06 - 8.97 respectively. The seafloor where the landslide sediments were deposited is a slope with sea depths ranging from 200 up to 700 meters and spread offshore at the south, east and north of Kai Archipelago. Seismicity in this area is related to intense earthquakes that occurred in the subduction zone of the Banda Sea.
