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 ...
Following the earthquake, the Japan Meteorological Agency (JMA) issued a 'Nankai Trough Earthquake Extra Information' advisory [23] that the probability of a megathrust earthquake along the Nankai Trough increased from a 0.1% per week to 1% chance [24] in what was the first advisory of its kind but clarified that it was not imminent.
The northeastern tip of the Noto Peninsula has been subject to an earthquake swarm for the last three years, with the largest earthquake being a M JMA 6.5 event that took place in May 2023. [13] The 1 January 2024 mainshock was the strongest to hit the peninsula since records began in 1885. [14]

Aftershocks of this earthquake were stronger than the Great Hanshin earthquake in 1995, but they happened much less frequently. Over 200 aftershocks were observed in the first 24 hours, with about 400 in total over the first seven days. The largest ones (with M j 5.0 or greater) were June 14, 9:20: M j 5.7: Max. seismic intensity reached Strong 5;
The earthquake was followed by multiple aftershocks within less than an hour, three of which registering magnitude 5.3. The earthquake itself has been considered an aftershock of the 2011 Tōhoku earthquake which had occurred almost ten years prior. [8] The earthquake left three people dead, and at least 186 injured.
The 2016 Fukushima earthquake struck Japan east-southeast of Namie, Fukushima Prefecture at 05:59 JST on November 22 (20:59 Nov 21 UTC) with depth of 11.4 km (7.1 mi). The shock had a maximum intensity of VII (Very strong) on the Mercalli scale .
The 2015 Ogasawara earthquake was a 7.8 magnitude earthquake which struck offshore Japan 189 km (117 mi) west northwest of Chichi-jima in the Ogasawara Islands on May 30 at a depth of 664.0 km (412.6 mi). [1] The shaking of the earthquake was observed almost all over Japan, [2] as it was one of the largest deep-focus earthquakes recorded worldwide.
