New Approaches to Coastal Zone Hazard Early Warning Systems<br />

Prof. Evgeny Kontar<br />

Coastal zone, shelf and continental slope are quickly becoming new major areas of industrial<br />

technological development owing to growing population in coastal regions and vast natural resources<br />

such as fish, oil, and gas available in these areas. Understanding risks of natural and human-made<br />

coastal zone hazards contributes to strengthening the scientific and technological basis of a number of<br />

industries including oil/gas production and transport. Traditional ways to evaluate risks of earthquakes<br />

and tsunamis (e.g., through analyzing historic data) are often not comprehensive enough and may<br />

result in lower estimates of the actual risks of these hazards, while a combined approach developed<br />

recently at P.P.Shirshov Institute of Oceanology of the Russian Academy of Sciences provides more<br />

accurate evaluations, which may affect significantly human research and industrial activities in the<br />

coastal areas. We report here some new ideas, approaches and preliminary results in the development<br />

of tsunami warning systems based on a complex monitoring system using the deep-ocean cable<br />

installations and bottom observatories located in the vicinity of the oil and gas drilling platforms which<br />

are cable connected to data processing centers. Operation of such systems is to be combined with<br />

satellite survey as well as with scientific cruise investigations. Also we report here some results of the<br />

EU project which was desined to disseminate information to scientific and industrial communities on<br />

combined risks of submarine contaminated groundwater discharge, saltwater intrusion, coastal zone<br />

earthquakes, landslides, and tsunamis. This information can be introduced targetting potential risk<br />

groups, including local coastal zone authorities and the general public, to enhance general risk<br />

awareness.<br />
