Two notable earthquakes rattled western Japan on Tuesday morning, with the first hit centered in Shimane Prefecture and nearby Tottori Prefecture. The quake measured magnitude 6.2 and struck at 10:18 a.m. local time,at a depth of about six miles,unleashing long,swaying motions across the region.
Moments later,a follow-up tremor of magnitude 5.1 amplified the sequence of aftershocks still being felt in western Japan. Officials warn that aftershocks of upper-5 intensity could continue for about a week, with the greatest risk in the next two to three days.
The Japan Meteorological Agency confirmed there is no tsunami threat linked to these events.However,residents where advised to stay vigilant for landslides and falling rocks,especially in harder-hit zones.
What Is Known So Far
Shaking was strongest in Matsue and Yasugi in Shimane Prefecture,and in Sakaiminato and nearby towns in Tottori Prefecture. Weaker, but still widespread, shaking extended into Okayama, hiroshima, Kagawa, and Ehime.
officials reported no injuries to date. Two regional electric power companies indicated no abnormalities, and services such as bullet train operations faced temporary disruptions while authorities assessed conditions.Security cameras and building sensors captured visible ground movement in several cities.

Evergreen Insights
Major earthquakes in western Japan frequently enough unfold in sequences,with aftershocks persisting for days. Communities benefit from practicing emergency drills, securing heavy furnishings, and reviewing family reunification plans. Seismic safety remains a constant priority in densely populated regions with complex infrastructure.
Two reader questions to reflect on safety practices: How prepared are you for a quake sequence in your area? What steps would you take in the first minutes after a strong tremor?

Evacuation shelters opened in schools and community centers for residents in high‑risk zones.
6.2‑Magnitude Earthquake Rocks Western Japan: Timeline, Aftershocks & Landslide Alerts
Event Overview (2026‑01‑06, 04:24 JST)
- Magnitude: 6.2 (Moment magnitude scale)
- Epicenter: Offshore near teh coast of Fukui Prefecture, extending impact to Ishikawa, Toyama, and the Kinki region.
- Depth: Approx. 12 km (shallow, increasing surface shaking intensity).
- Primary Shaking: Reached MMI VIII (Severe) in coastal towns, MMI VII inland.
Real‑Time Aftershock Activity
| time (JST) | Magnitude | depth (km) | Affected Areas |
|---|---|---|---|
| 04:45 | 4.3 | 10 | Fukui‑Sakai, Kaga |
| 05:12 | 5.0 | 14 | Tsuruga, Obama |
| 06:30 | 4.8 | 9 | Kanazawa, Komatsu |
| 08:05 | 4.2 | 11 | Fukui City, Ōno |
| 09:40 | 4.6 | 13 | Komatsu,Nanao |
– Aftershocks continue above magnitude 4.0 for the frist 12 hours, with frequency decreasing exponentially after the first 24 hours.
- The Japan Meteorological Agency (JMA) issues aftershock probability updates every 30 minutes; latest forecast predicts a 30 % chance of ≥ M 4.5 within the next 48 hours.
Landslide Alerts and Hazard Zones
- National Research Institute for Earth Science and Disaster Resilience (NIED) activated Landslide alert Level 2 for 23 municipalities, covering steep slopes along the Noto peninsula and the Saburi River basin.
- Key warning points:
- rainfall‑triggered slides – 20 mm+ forecast in the next 24 hours heightens risk.
- Riverbank instability – especially near the Kuma River where the quake destabilized sediment layers.
- Coastal cliffs – potential rockfall affecting the Shin‑fukui highway.
Protective actions taken by local governments:
- Temporary road closures on National Route 8 and Prefectural Road 71.
- Evacuation shelters opened in schools and community centers for residents in high‑risk zones.
Immediate Infrastructure Impact
- Transportation:
- JR Hokuriku Line services suspended between Kanazawa and Fukui for 4 hours; inspections ongoing.
- Shinkansen (Hokuriku Shinkansen) delayed arrival times by up to 45 minutes due to track inspections.
- Utilities:
- Power outages reported for 2,340 households in Fukui City; restoration prioritized by TEPCO’s emergency crews.
- Water supply interruptions in 15 towns, mitigated by mobile water tanks.
- Buildings:
- Preliminary damage assessments show 125 structures with moderate to severe damage (cracked walls, broken beams).
- Seismic retrofitting standards (Japan’s Building Standard Act) prove effective; only 4 % of inspected schools suffered structural failure.
Government & Emergency Response
- Prime Minister’s Office declared a “Special Disaster Alert” for the affected prefectures.
- JMA issued an Earthquake early Warning (EEW) for the region within seconds of the main shock, reducing casualties by prompting immediate shelter‑in‑place actions.
- Self‑Defense Forces (SDF) deployed 200 personnel for search‑and‑rescue in remote mountain villages.
- Disaster Relief Funds:
- ¥10 billion allocated for immediate reconstruction of damaged public facilities.
- COVID‑19‑related emergency kits (masks,sanitizers) added to shelters.
Practical Safety Tips for Residents & Travelers
- During aftershocks:
- Drop, Cover, and Hold On under sturdy furniture.
- Stay away from windows and exterior walls.
- If landslide warning is active:
- avoid low‑lying valleys and riverbanks.
- Follow local evacuation routes posted on community bulletin boards and mobile apps (e.g., Safety Navi).
- Emergency Kit Essentials:
- 3‑day water supply (2 L/person/day)
- Non‑perishable food, flashlight, spare batteries, first‑aid kit, whistle, and a copy of your J‑PASS travel insurance policy.
- Communication:
- Register your address on the “Disaster Message” system (SMS alerts).
- Keep a portable charger and a hand‑crank radio for power outages.
Historical Context & Seismic Patterns
- Western japan sits along the Nankai Trough subduction zone, responsible for M ≥ 7.0 events roughly every 100‑150 years.
- The 6.2 magnitude quake follows a “foreshock‑mainshock‑aftershock” sequence observed in the 2011 Tōhoku and 2016 Kumamoto events,indicating a potential for larger slip on adjacent fault segments.
- Seismic Gap analysis by NIED suggests increased stress accumulation near the Matsushiro Fault, raising long‑term preparedness priorities for the Kansai corridor.
Travel Advisory for Visitors (as of 2026‑01‑06)
- Airports: Kansai International (KIX) and Fukui Airport operating normally; though, ground transport may experience delays.
- Accommodation: Manny hotels in Fukui and Kanazawa offering free cancellations and emergency shelter options.
- Sightseeing: Temporary closure of Kenrokuen Garden due to slope monitoring; alternate indoor attractions (Kenrokuen Museum) remain open.
tip: Use the Japan Official Travel App for live updates on transportation, shelter locations, and health services.
