Announcing the 3rd Samani Disaster Prevention Seminar, “The Possible Return of a Megathrust Earthquake”
Since the year before last, Samani has been hosting the “Samani Disaster Prevention Seminars,” a series of lectures designed to provide an engaging way to learn about natural disasters and disaster preparedness through the relationship between disasters and the local natural environment.
As the third session of this year, we will hold a lecture titled “The Possible Return of a Megathrust Earthquake— A Report on Seafloor Observation Results Along the Kuril Trench Conducted by Tohoku University, Hokkaido University, and the Japan Agency for Marine-Earth Science and Technology.”
🔸Date/Time: Thursday, September 17, 2026, 6:30 PM – 8:15 PM
🔸Location: Samani Community Center, Culture Hall
- Lecture 1: Strain Accumulation Along the Kuril Trench Confirmed by Seafloor Observations—The Possibility of an Imminent Recurrence of a Megathrust Earthquake Like Those in the 17th Century
▪️Speaker: Hiroaki Takahashi, Professor, Hokkaido University Earthquake and Volcano Research and Observation Center
- Lecture 2: Is Your Home Safe? Seismic Retrofitting of Buildings and Measures to Prevent Furniture from Toppling
▪️Speaker: Takashi Imai, Hokkaido Prefectural Research Organization, Northern Architecture Research Institute Chief Researcher (Regional Disaster Prevention)
This Disaster Prevention Seminar consists of a two-part lecture series. Part 1 features a report on “Seafloor observation results suggesting the imminent possibility of a mega-earthquake—the largest since the 17th century—off the coast of Hokkaido,” published this past February by Tohoku University, Hokkaido University, and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). Part 2 uses models and other materials to explain seismic retrofitting for buildings and measures to prevent furniture from toppling over, key concerns in the event of a major earthquake.
Both the recent Kumamoto Earthquake, which recorded a maximum seismic intensity of 7, and the Great East Japan Earthquake caused extensive damage, including the collapse of many homes. Please join us in thinking about how to prepare mentally and practically for a major earthquake.
Admission is free, and no registration is required.
