Key Facts
• January 1, 2024: Noto Peninsula Earthquake, magnitude 7.6, maximum intensity 7.
• 80,000 buildings damaged, mostly old wooden houses, 200+ fatalities reported.
• 40% of deaths caused by crushing, 20% by asphyxiation or respiratory failure.
• South Sea Trough Earthquake: 80% chance within 30 years, 41,000 deaths predicted.
• 69,000 buildings expected to collapse, 3,900 deaths from structural failures.
• Post-1981 seismic standards reduced damage; stricter 2000+ standards more effective.
• Seismic diagnosis costs $3000 or less with subsidies; mandatory for pre-2000 homes.
• Average seismic retrofitting cost: $260,000; subsidies range from $120,000 to $200,000.
• Retrofitting uses metal fittings and structural reinforcements to minimize costs.
• Retrofitting can be done while residents remain in their homes.
Summary
The Noto Peninsula Earthquake of January 2024 highlighted the critical role of seismic-resistant housing, with 80,000 buildings damaged and over 200 fatalities. Many deaths were caused by structural collapses, emphasizing the importance of updated seismic standards. The South Sea Trough Earthquake, with an 80% likelihood in the next 30 years, could result in 41,000 deaths and 69,000 building collapses in Tokushima alone. Seismic retrofitting, particularly for homes built before 2000, is essential. Subsidies significantly reduce the cost of seismic diagnosis and retrofitting, making it accessible to more homeowners. Retrofitting involves targeted reinforcements, such as metal fittings and structural panels, and can be completed in 1–1.5 months, even while residents remain in their homes. Experts urge immediate action to ensure safety and minimize future earthquake damage.
