    Abstract

    © Near Surface Geoscience Conference & Exhibition 2018. All rights reserved. The study presents novel data on the potential geological hazards on the shelf of the Sea of Okhotsk. The near-surface characterization is mainly based on the analysis of the conventional 3D seismic dataset (5-100 Hz). The special processing of the 3D data and the amplitude-based approach to the interpretation (AVO-analysis, seismic inversion) allows us to evaluate geohazards at different scales over a wide range of depths from the first meters to nearly 1 km from the sea bottom. The main types of the potential geohazards in the area are the gas-bearing sediments, zones of a focused fluid discharge, intervals with abnormal pore pressure and faults.

    Curtin would like to pay respect to the Aboriginal and Torres Strait Islander members of our community by acknowledging the traditional owners of the land on which the Perth campus is located, the Whadjuk people of the Nyungar Nation; and on our Kalgoorlie campus, the Wongutha people of the North-Eastern Goldfields.
