Existing conventional systems for tsunami warning found at the market are exclusively prototypes developed within more or less scientific projects. Based on actual determined earthquake parameters a matching with pre-calculated scenarios is made, which allows a prediction of arrival time and amplitude of the tsunami wave for the relevant coastlines. With this approach in principle only a limited number of standard situations can be taken into account. In case of untypical situations these systems fail because the pre-calcualation process takes some time.

TOAST follows another approach which is based on "on the fly" simulation of tsunami propagation. By this approach TOAST can react flexible in untypical situations. E.g. earthquake in supposed inactive regions or earthquakes exceeding the magnitude threshold assumed for a region. Before the 2004 tsunami most people wouldn't have thought about a magnitude 9.4 earthquake in the Sumatra region. Also the recent events like the one in Chile (27.02.2010, M8.9) or the catastrophical Honshu Earthquake (11.03.2011, M9.1) are best examples. All of these events were untypical in the sense, that they were not expected and therefore no pre-calculated scenarios were existing.
