Abstract

http://dx.doi.org/10.17014/ijog.vol4no1.20092Submarine sliding frequently cause tsunami or a high velocity big wave around the submarine slid- ing area which enable to reach a long distance. This sliding is not always as a causal factor for hazard and even associate with storm and earthquake. Some of them occur in a narrow area and it’s just formed due to gravitational movement. Different with mechanism of landslide, which is commonly due to water saturated soil, the submarine sliding is a more complex event. The submarine sliding is an important natural process which causes a big volume of sediment mass moves from a shallow area to a much deeper area of seafloor. There are many types and causal factors of seafloor instability, but the sliding terminology is predominantly used for the phenomena. A variety of seafloor materials, environments and sediment masses are some extreme influential factors in creat- ing the types of submarine sliding. The reflector of seismics is usefull to interpret the indications of the occurrence of geological structure and sub-marine slumping In case of the Flores Sea, earthquake is a major causal factor for creating submarine sliding. The bigger magnitude of earthquake, the greater the dimension of submarine sliding. Eventually, it may affect to the more possible occurrence of a potential hazardous tsunami.

Description

The spirit to improve the journal to be more credible is increasing, and in 2012 it invited earth scientists in East and Southeast Asia as well as some western countries to join the journal for the editor positions in the Indonesia Journal of Geology. This is also to realize our present goal to ...
