How Often Does Japan Have Earthquakes?<\/h2>\n\n\n\n
Most of Japan\u2019s 5,000 earthquakes go unnoticed due to its low magnitude rating, or because the hypocenter (the point where an earthquake ruptures below the surface of the Earth) is far from the coast of Japan. About 3,800 earthquakes with a recording of 3.0 \u2013 3.9 occur per year and around 900 with a magnitude of 4.0 \u2013 4.9.<\/p>\n\n\n

The table shows the annual average of earthquakes in Japan. Data from the Japan Meteorological Agency<\/a>.<\/figcaption><\/figure><\/div>\n\n\n Why Does Japan Have so Many Earthquakes?<\/h2>\n\n\n\n
Japan\u2019s high number of earthquakes is due to its geographical location along the Pacific Ring of Fire<\/a> <\/strong>\u74b0\u592a\u5e73\u6d0b\u706b\u5c71\u5e2f (kantaiheiyoukazantai<\/em>). This 40,000 km long chain consists of at least 450 volcanoes<\/strong>. In Japan alone, there are around 265 volcanoes classified as potentially active.<\/p>\n\n\n\n

The Japan Trench is an 800-meter-long deep oceanic trench<\/strong> in the northwestern part of the Pacific, with a depth of 8,410 meters. In 2006, seismically active volcanoes with a height of 50 meters were discovered 5,000 meters within the trench and are believed to be responsible for the Tohoku earthquake and tsunami of March 2011<\/a>.<\/p>\n\n\n\n
What to do in the Event of an Earthquake<\/h2>\n\n\n\n
What if an unexpectedly intense earthquake occurs while you are in Japan? If you are indoors<\/strong>, seek shelter under a stable table or door frame and stay away from anything that could fall on you. If you are outside<\/strong>, find an open area away from trees, machines, and buildings.<\/p>\n\n\n\n

<\/figure><\/div>\n\n\n<\/div>\n\n\n\nAlso, pay attention to announcements or warnings made from loudspeakers <\/strong>in most cities and towns in Japan. If you have a phone with a Japanese phone number, you will receive a notification to your smartphone<\/strong>. This extends to users with data-only SIM cards<\/a> as well.

The Most Significant Earthquakes in Japanese History<\/h2>\n\n\n\n
In Japan\u2019s history, several earthquakes with a 7.0 and stronger magnitude have resulted in many victims and destruction in its wake. Some of the most destructive earthquakes occurred almost a century ago, while others happened in the recent past.<\/p>\n\n\n\n
The Great Kanto Earthquake of 1923<\/h3>\n\n\n\n
On September 1, 1923, an earthquake with a magnitude of 7.9 hit the Kanto region<\/a> and destroyed most of Tokyo<\/a> and Yokohama<\/a>. With more than 100,000 deaths, the Great Kanto Earthquake<\/strong> \u95a2\u6771\u5927\u9707\u707d (kanto daishinsai<\/em>) went down as one of the most destructive earthquakes in Japan\u2019s history. The aftermath also triggered a massive city fire, and casualties rose to over 140,000.<\/p>\n\n\n\n

<\/figure>\n<\/figure>\n\n\n\nThe earthquake not only led to major fires in the metropolitan region but also resulted in a 12-meter-high tsunami wave that hit Sagami Bay. The bay, located in the south of Kanagawa Prefecture, was also the hypocenter of the earthquake, and the landmasses of the bay shifted two meters upwards during the quake.<\/p>\n\n\n\n
The Kobe Earthquake of 1995<\/h3>\n\n\n\n
On January 17, 1995, an earthquake with a magnitude of 7.3 hit the\u00a0city of Kobe. Over 4,500 people died during the Kobe Earthquake, also known as\u00a0the Hanshin-Awaji Earthquake disaster<\/strong>\u00a0\u962a\u795e\u30fb\u6de1\u8def\u5927\u9707\u707d (Hanshin Awaji daishinsai)<\/em>. The earthquake’s hypocenter occurred 20\u00a0km southwest of Kobe’s city center, 16\u00a0km below the Earth’s surface.<\/p>\n\n\n\n

After the force of the Kobe Earthquake, the bridge’s piers moved almost a meter apart.<\/p>\n\n\n\n
Nowadays, Japan celebrates January 17 as Disaster Response Volunteer Day<\/strong> \u9632\u707d\u3068\u30dc\u30e9\u30f3\u30c6\u30a3\u30a2\u306e\u65e5(B\u014dsai to Borantia no Hi<\/em>). In addition, the Kobe Luminarie<\/a> \u795e\u6238\u30eb\u30df\u30ca\u30ea\u30a8 is held in Kobe every December to commemorate the victims of the earthquake<\/strong>.<\/p>\n\n\n\n
The Tohoku Earthquake and Tsunami of 2011<\/h3>\n\n\n\n
The Tohoku earthquake<\/strong> and tsunami <\/strong>\u6771\u65e5\u672c\u5927\u9707\u707d (Higashi-Nihon daishinsai<\/em>) occurred on March 11, 2011. With a magnitude of 9.1, this earthquake is the strongest ever recorded in Japan. The ocean megathrust earthquake occurred off the Sanriku coast by Miyagi Prefecture, about 130 km east of Sendai and 370 km northeast of Tokyo.<\/p>\n\n\n\n
The 23-meter-high tsunami wave triggered by the earthquake flooded over 500 km\u00b2 of the Japanese Pacific coastline. The nuclear disaster at the Fukushima nuclear power plant gave the Tohoku Earthquake the nickname “triple catastrophe.”<\/strong><\/p>\n\n\n\n

The destruction and nuclear disaster forced almost half a million people to leave their apartments and houses.<\/p>\n\n\n\n
Just as the Kanto and Kobe earthquakes had, the Tohoku<\/a> earthquake and tsunami altered the plate tectonics. The main island of Honshu shifted 2.4 meters to the east, and the Oshika peninsula in Miyagi Prefecture sank by 120 cm. In the days and weeks after the disaster, around 500 earthquakes with a magnitude of 5.0 to 7.0 have been recorded.<\/p>\n\n\n\n
Earthquakes are something to expect at any time of the day<\/strong> in Japan but don\u2019t worry. Most modern Japanese buildings have earthquake-proof construction<\/strong> of cushioned pillars anchored in massive concrete foundations. That will ensure getting through unscathed during such an event in Japan.
