Region at risk: coasts located near subduction zones or across ocean basins from subduction zones are most at risk, areas at greatest risk are the pacific ocean and the mediterranean sea. Natural service functions: tsunamis bring very few service functions, they can carry fertile sediment onto the land that can then be used for agriculture. Lessons from the 2004 tsunami: effective tsunami warning systems are needed around all oceans where tsunamis can occur, in 2006, a new warning system became operational in the indian ocean, a warning system by itself is not enough.
