List of earthquakes in Japan

"Japanese earthquake" redirects here. For the 11 March 2011 earthquake in the Tōhoku region, see 2011 Tōhoku earthquake and tsunami.

This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale (M_L) or the moment magnitude scale (M_w), or the surface wave magnitude scale (M_s) for very old earthquakes. The present list is not exhaustive, and furthermore reliable and precise magnitude data is scarce for earthquakes that occurred before the development of modern measuring instruments.

Earthquakes M5.5+ around Japan (1900–2016)
M7.0–7.9=163 EQs, M8.0+=14 EQs.^[1]

History

Although there is mention of an earthquake in Yamato in what is now Nara Prefecture on August 23, 416, the first earthquake to be reliably documented took place in Nara prefecture on May 28, 599 during the reign of Empress Suiko, destroying buildings throughout Yamato province.^[2][3][4] Many historical records of Japanese earthquakes exist. The Imperial Earthquake Investigation Committee was created in 1892 to conduct a systematic collation of the available historical data, published in 1899 as the Catalogue of Historical Data on Japanese Earthquakes.^[4]

Following the 1923 Great Kantō earthquake, the Imperial Earthquake Investigation Committee was superseded by the Earthquake Research Institute in 1925.^[3] In modern times, the catalogues compiled by Tatsuo Usami are considered to provide the most authoritative source of information on historic earthquakes, with the 2003 edition detailing 486 that took place between 416 and 1888.^[3]

Earthquake measurement

In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. This is similar to the Modified Mercalli intensity scale used in the United States or the Liedu scale used in China, meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake releases at its epicenter (its magnitude) as the Richter scale does.^[5]

Unlike other seismic intensity scales, which normally have twelve levels of intensity, shindo (震度, seismic intensity, literally "degree of shaking") as used by the Japan Meteorological Agency is a unit with ten levels, ranging from shindo zero, a very light tremor, to shindo seven, a severe earthquake.^[5] Intermediate levels for earthquakes with shindo five and six are "weak" or "strong", according to the degree of destruction they cause. Earthquakes measured at shindo four and lower are considered to be weak to mild, while those measured at five and above can cause heavy damage to furniture, wall tiles, wooden houses, reinforced concrete buildings, roads, gas and water pipes.^[5]

The dates of the quake have also been listed variously as October 14 (incorrect date) and November 24.^[7] It was at this point in time that the Japanese confirmed the link between earthquakes and tsunamis, and began keeping detailed records of them. Their tsunami records are studied by geologists to this day.^[citation needed]

Just before the shaking could be felt, a sound like a cannon was reportedly heard intermittently from the direction of the estuary near the Maruyama River. During the earthquake, the ground in the town of Tokyooka experienced strong seismic vibrations for 16 seconds. As most of the buildings of the time were wooden, many of them were destroyed at once during the initial earthquake. In the fire that broke out subsequently, half of Toyooka was burned down, with many deaths resulting (a reported 8% of the town's population.) 272 deaths were confirmed to have occurred in the Kinosaki area.
