On Saturday March 26, Akita University held a lecture titled on "Thinking About Tsunami Disaster Prevention for Katagami City - Five Years After the Great East Japan Earthquake-"
This lecture was organized to encourage people to think of tsunami prevention for Katagami City, which is a wide and low-lying area. On that day around 50 citizens attended the lecture.
First, Professor Hideo Matsutomi, director of the local disaster prevention research center, gave a lecture. He explained the basic idea of proactive tsunami protection measures. He talked about the importance of facilities such as seawalls, systems such as education for disaster prevention, and community development such as placement of evacuation passages. He said "More importantly, all of these need to function comprehensively. This idea has not changed since more than 30 years ago."
Then Lecturer Kazuya Watanabe from the Graduate School of Engineering Science explained about tsunami evacuation by using floating shelters.
