AB: Assessment of potential of geo-hazards and their risks to populated coastal areas is becoming an important domain of scientific research and mitigation management. Coastal zone, shelf and continental slope are quickly becoming new major areas of industrial technological development owing to growing population in coastal regions and vast natural resources such as fish, oil, and gas available in these areas. Understanding risks of natural and human-made coastal zone hazards contributes to strengthening the scientific and technological basis of a number of industries including oil/gas production and transport. Traditional ways to evaluate risks of submarine earthquakes and tsunamis (e.g., through analyzing historic data) are often not comprehensive enough and may result in lower estimates of the actual risks of these hazards, while a combined approach provides more accurate evaluations, which may affect significantly human research and industrial activities in the coastal areas. We report here some new ideas, approaches and preliminary results in the development of tsunami warning systems based on a complex monitoring system using the deep-ocean cable installations and bottom observatories located in the vicinity of the oil and gas drilling platforms which are cable connected to data processing centers. Operation of such systems is to be combined with satellite survey as well as with scientific cruise investigations.
