In the 10 years since the Great East Japan Earthquake and tsunami of March 11, 2011, scientists have sought answers to a variety of questions relating to the deadly tsunami that began tearing through coastal communities just 15 minutes after the quake.

Researchers have probed how a tsunami gathers height as it nears a shoreline and how this affects the damage it can cause. They*ve also begun to assess technologies for the early detection of tsunamis and improving tsunami observing systems across Japan.

※The speed of a tsunami offshore is the same as a jet airplane and its speed inland similar to Usain Bolt,§ says Nobuhito Mori, a professor in the Coastal Disaster Research section of the Disaster Prevention Research Institute at Kyoto University.
