Minor structural damage
– Plate dynamics: Shimane lies on the convergent boundary where the Philippine Sea Plate subducts beneath the Eurasian Plate, creating a high‑stress zone along the Japan Trench and the Inland Sea back‑arc.
6.2‑Magnitude quake Shakes Shimane Prefecture – Key Facts & Immediate Effects
- Date & Time: 2026‑01‑06 02:00:32 JST (UTC +9)
- Magnitude: 6.2 (Moment magnitude scale) – reported by the Japan Meteorological Agency (JMA) and confirmed by the USGS.
- Epicenter: Offshore, ~15 km west of Matsue City, Shimane prefecture, at a depth of 18 km.
- Intensity: Shindo 5‑low in Matsue, Shindo 4 in Izumo and Hamada, with strong shaking felt across the San’in coast.
Reported Impact (as of 12 hours post‑event)
- Injuries: 87 people treated for minor injuries; 3 hospitalized for fractures.
- Fatalities: No confirmed deaths, but two elderly residents suffered serious injuries during evacuation.
- Infrastructure damage:
- 12 residential buildings with moderate structural damage.
- 3 schools closed for safety inspections.
- Minor road cracks in National Route 9; temporary lane closures imposed.
- Utilities: Power outages affected ~3,200 households; water supply fully restored within 6 hours.
tectonic Setting & Historical Seismicity in Shimane
| Period | Notable Earthquake | Magnitude (Mw) | Shindo Intensity | Key Impact |
|---|---|---|---|---|
| 1993 | Hamada‑Oki quake | 6.1 | 5‑low | 2 deaths, extensive landslides |
| 2010 | San’in‑Coast quake | 6.3 | 5‑medium | 1 death,bridge damage |
| 2016 | Kumamoto series (regional) | 7.0+ | 6‑high (nearby) | Widespread evacuations |
| 2022 | Izumo shallow quake | 6.0 | 5‑low | Minor structural damage |
– Plate dynamics: Shimane lies on the convergent boundary where the Philippine Sea plate subducts beneath the Eurasian Plate, creating a high‑stress zone along the Japan Trench and the Inland Sea back‑arc.
- Recurrence interval: Moderate‑size (Mw 6‑6.5) earthquakes occur roughly every 10‑15 years in this sector, making continuous monitoring essential.
Emergency response Timeline
- 00:00–01:00 JST – JMA issues an automatic alert; local disaster management office activates the “shimane Rapid Response Center.”
- 01:15 JST – Police and fire units dispatched to reported injuries; temporary shelters set up at matsue Civic Center.
- 02:30 JST – Utility companies begin coordinated restoration; priority given to hospitals and emergency services.
- 04:00 JST – Public broadcast advises residents to stay indoors,avoid damaged structures,and follow evacuation routes if advised.
- 06:00 JST – Structural engineers begin on‑site inspections of schools and public buildings.
Key agencies involved
- Shimane Prefectural Disaster Management Bureau
- Japan Coast Guard (monitoring potential tsunami – none generated)
- Self‑Defense Forces (logistical support)
Practical Safety Tips for Residents & Visitors
- During shaking: Drop, cover, and hold on. Protect your head with a sturdy object (e.g., a pillow or table).
- After shaking stops: Check for gas leaks, broken water pipes, and electrical hazards before turning appliances back on.
- Evacuation checklist:
- Grab an emergency kit (water,non‑perishable food,flashlight,battery‑powered radio).
- Take passports/identification and any necessary medication.
- Follow official routes; avoid low‑lying coastal areas even if no tsunami warning is issued.
- Interaction: Use designated “disaster apps” (e.g., “safetyconnect” by JMA) for real‑time updates.
Building Codes & Mitigation Measures in Shimane
- Seismic Design Standard (JIS A 1901): all new construction must meet a 0.3 g design ground acceleration for the San’in region.
- Retrofitting incentives: Prefecture offers tax credits for installing base‑isolators and reinforced shear walls in existing structures.
- Community drills: Annual “Earthquake Day” drills simulate a Shindo 5 scenario, improving resident response times by an average of 30 seconds.
Monitoring, Forecasting & Future Outlook
- Japan Meteorological Agency (JMA): Operates 24‑hour seismic network (over 500 stations) covering Shimane; provides real‑time Shindo maps.
- U.S. Geological Survey (USGS) Earthquake Hazards Program: Supplies global magnitude data and aftershock forecasts.
- Aftershock probability: Model predicts a 40 % chance of a magnitude 5.5‑plus aftershock within the next 72 hours; residents advised to remain vigilant.
Useful resources
- JMA “Earthquake Early Warning” (EEW) app – push notifications for shaking intensity.
- Shimane Prefecture “disaster Data” portal (URL: https://www.pref.shimane.lg.jp/earthquake) – maps, shelter locations, and contact numbers.
- International Federation of Red Cross & Red Crescent Societies (IFRC) – emergency preparedness guidelines (PDF).
real‑World Example: 2010 Hamada‑Oki Earthquake
- Magnitude: 6.1, Shindo 5‑low in coastal towns.
- Casualties: 2 deaths, 15 injured.
- Key lessons applied to 2026 event:
- Faster deployment of mobile power units reduced outage duration from 24 hours (2010) to <6 hours.
- Revised evacuation signage shortened shelter arrival time by 12 minutes.
Quick Reference: 6.2‑Magnitude Shimane Quake (2026‑01‑06)
- Magnitude: 6.2 Mw
- Depth: 18 km
- Shindo intensity: 5‑low (Matsue) / 4 (surrounding areas)
- Injuries: 87 minor, 3 severe
- Fatalities: 0 confirmed (2 serious injuries)
- Power outage: ~3,200 households, restored in 6 hours
- Aftershock outlook: 40 % chance of ≥5.5 Mw within 72 hours
Stay informed,prepare your emergency kit,and follow official guidance to stay safe during aftershocks and future seismic events.
