ABSTRACT
Even though ideally one would like to have a global tsunami warning system, somewhat similar to a global weather forecasting system, in practice this is not achievable, at least for the following reasons. Whereas the atmosphere is continuous, the oceans are not, they are separated by continents (Figure 38.1). The Pacific, Atlantic and Indian oceans are connected in the south through,
what is termed as the Southern Ocean. The Pacific and Atlantic oceans are connected to the Arctic Ocean in the north. The Indian and Arctic Ocean are not directly connected. In addition to these geographical considerations, since different countries border on different oceans, it makes perfect sense for each ocean to have its own tsunami warning system.
