Major Earthquakes in Japan List, Name, Year, Magnitude of Largest Earthquakes

Major Earthquakes in Japan: On January 2, 2024, a powerful earthquake rocked central Japan, resulting in significant devastation, loss of life, and infrastructure damage. The seismic event claimed the lives of at least six people and left tens of thousands of homes without power.

Japan, positioned along the notorious “Ring of Fire,” characterized by a series of active volcanoes and tectonic plate boundaries encircling the Pacific Basin, is prone to frequent and intense seismic activity. Approximately 20% of the world’s earthquakes with a magnitude of 6 or higher occur in this region, amounting to around 2,000 perceptible quakes annually. In this article, you will get a List of Major Earthquakes in Japan.

Earthquakes in Japan History

Japan has a long history of seismic activity, with earthquakes playing a significant role in shaping the nation’s landscape. The country sits on the Pacific Ring of Fire, a zone known for high tectonic activity. One of the most devastating earthquakes was the Great Kanto Earthquake in 1923, causing widespread destruction and claiming over 140,000 lives.

The 2011 Tohoku earthquake and tsunami were also catastrophic, triggering a nuclear disaster at Fukushima. Japan continually implements advanced seismic technology and strict building codes to mitigate earthquake risks, showcasing its resilience in the face of natural challenges.

List of Major Earthquakes in Japan

Japan is situated in a seismically active region, and its history is marked by numerous earthquakes that have had profound impacts on the country. Here are some significant earthquakes in Japan’s history:

Year Earthquake Name Magnitude Impact
1498 Meio Nankai Earthquake 8.6-9.1 Massive tsunami with waves reaching the Philippines
1854-1855 Ansei Edo Earthquakes (series of three) 7.0-7.3 Widespread damage and fires in the Edo region
1923 Great Kanto Earthquake 7.9 Devastation in Tokyo and Yokohama, 140,000+ casualties
1944 Showa Nankai Earthquake 7.9 Tsunami causing significant damage in Tokushima, Kochi
1959 Ise Bay Typhoon and Earthquake Not Applicable Landslides and debris flows after Typhoon Vera
1964 Niigata-Chuetsu Earthquake 7.5 Widespread damage to buildings and infrastructure
1995 Kobe Earthquake (Great Hanshin Earthquake) 6.9 Over 6,400 casualties, extensive infrastructure damage
2011 Tohoku Earthquake and Tsunami 9.0 Mega-thrust earthquake, powerful tsunami, Fukushima disaster
2021-2022 Fukushima Earthquakes (series) Various Including a magnitude 7.3 quake in 2021 and 2022

Details about Major Earthquakes in Japan

  • Nankai Earthquake (1498): Often referred to as the Meio Nankai Earthquake, this event had an estimated magnitude of 8.6–9.1 and triggered a massive tsunami. The tsunami waves reached as far as the Philippines.
  • Ansei Edo Earthquakes (1854-1855): A series of three major earthquakes struck the Edo (now Tokyo) region during this period. The most destructive was the Ansei Edo earthquake in 1855, which had a magnitude of 7.0-7.3. These earthquakes caused widespread damage and fires.
  • Great Kanto Earthquake (1923): With a magnitude of 7.9, this devastating earthquake struck the Kanto region, including Tokyo and Yokohama. The quake and ensuing fires resulted in the deaths of over 140,000 people.
  • Showa Nankai Earthquake (1944): This earthquake, with a magnitude of 7.9, occurred off the coast of Nankai. It generated a tsunami that caused significant damage along the coasts of Tokushima and Kochi.
  • Ise Bay Typhoon and Earthquake (1959): In the aftermath of Typhoon Vera, which struck Japan in September 1959, heavy rainfall triggered a series of landslides in the Ise Bay region. The resulting debris flows caused the death of over 5,000 people.
  • Niigata-Chuetsu Earthquake (1964): With a magnitude of 7.5, this earthquake struck the Niigata region, causing widespread damage to buildings and infrastructure. It was notable for its effects on the engineering community’s approach to seismic design.
  • Kobe Earthquake (1995): The Great Hanshin Earthquake, with a magnitude of 6.9, struck near Kobe and Awaji Island. It resulted in the deaths of over 6,400 people and caused extensive damage to infrastructure, highlighting vulnerabilities in urban planning and construction.
  • Tohoku Earthquake and Tsunami (2011): This mega-thrust earthquake, with a magnitude of 9.0, triggered a powerful tsunami that struck the northeastern coast of Japan. The Fukushima Daiichi nuclear disaster was also a consequence of this event. It is considered one of the most powerful earthquakes recorded.
  • Fukushima Earthquakes (2021-2022): A series of earthquakes struck off the coast of Fukushima in 2021 and 2022, including a magnitude 7.3 quake in February 2021 and another with a magnitude of 7.3 in March 2022. These events revived concerns about nuclear safety and earthquake preparedness.

These earthquakes illustrate the seismic risk faced by Japan and the ongoing efforts to understand, mitigate, and respond to the challenges posed by such natural disasters. The country has implemented stringent building codes, early warning systems, and disaster preparedness measures to minimize the impact of future seismic events.

Japan’s Biggest Earthquakes

The strongest earthquake in Japan’s recorded history occurred on March 11, 2011. The 9.1 magnitude earthquake struck 130 kilometers east of Sendai, the largest city in the Tohoku region. The earthquake triggered a tsunami that killed nearly 20,000 people and caused a nuclear meltdown in Fukushima. The disaster is estimated to have caused $220 billion in damage.

5 Largest Earthquakes in Japan

Rank Earthquake Name Magnitude Date Impact
1 Tohoku Earthquake and Tsunami (2011) 9.0 March 11, 2011 Mega-thrust earthquake, powerful tsunami, Fukushima Daiichi nuclear disaster
2 Showa Nankai Earthquake (1944) 7.9 December 7, 1944 Off the coast of Nankai, generated a tsunami, significant damage along Tokushima and Kochi coasts
3 Great Kanto Earthquake (1923) 7.9 September 1, 1923 Devastated Tokyo and Yokohama, over 140,000 casualties, widespread destruction
4 Niigata-Chuetsu Earthquake (1964) 7.5 June 16, 1964 Affected Niigata region, widespread damage to buildings, influenced seismic design
5 Meio Nankai Earthquake (1498) Estimated 8.6-9.1 August 20, 1498 Massive tsunami, waves reaching the Philippines, extensive coastal damage
