Tsunamis most frequently occur in the Pacific Ocean, especially around the geologically active "Ring of Fire," which is a region with many subduction zones and tectonic plate boundaries prone to large undersea earthquakes. About 78-80% of confirmed tsunamis between 1900 and 2015 happened in this area, including off the coasts of Alaska, Chile, Japan, Indonesia, and Russia
. Other regions where tsunamis can occur, though less frequently, include the Atlantic Ocean and Caribbean Sea (about 8%), the Mediterranean Sea (6%), the Indian Ocean (5%), and some smaller seas like the Sea of Marmara in Turkey
. Tsunamis can be generated by undersea earthquakes, volcanic eruptions, landslides, or even meteorite impacts in any large body of water, but the Pacific Ocean remains the most tsunami-prone due to its tectonic activity
. In summary, tsunamis are most likely to happen along coastal areas facing subduction zones, with the vast majority occurring in the Pacific Ocean's Ring of Fire region. However, they can occur in all the world's oceans and some large inland seas
