Earthquake zone - earthquake

Japanese: 地震帯 - じしんたい

A belt-like area where earthquakes occur frequently. Globally, the most representative are the Circum-Pacific earthquake belt and the earthquake belt that runs from the Mediterranean coast through the Himalayas to the Malay and Indonesian islands. In plate tectonics theory, the belt-like distribution is along the plate boundary. In addition, seismic activity is distributed in a fine belt along active faults. The outer seismic belt is the earthquake belt that runs along the island arc on the Pacific side of the Japanese archipelago, and the inner seismic belt is the earthquake belt that runs along the Japan Sea coast of the Japanese archipelago. Within the Japanese archipelago, Fusakichi Omori, Akitsune Imamura, and others proposed the Edogawa seismic belt, the Shinano River seismic belt, and the Yodogawa seismic belt, but in recent years, as a result of progress in research on the spatial distribution of epicenters, there is a strong opinion that it is better to express earthquake-prone areas as three-dimensional ``earthquake nests'' rather than a two-dimensional belt-like distribution.

地震の特に多く発生する帯状の地域。世界的には環太平洋地震帯と地中海沿岸からヒマラヤ山地を経てマレー，インドネシア諸島へぬける地震帯とが代表的。プレートテクトニクス理論では帯状分布はプレート境界に沿う。また，活断層ぞいでは地震活動が細かな帯状に分布する。日本列島の外側の太平洋側を島弧に沿って走る地震帯を外側地震帯，日本列島の日本海沿岸に沿う地震帯を内側地震帯という。日本列島内部では，大森房吉，今村明恒らにより，江戸川地震帯，信濃川地震帯，淀川地震帯などが唱えられたが，近年では震源の空間的分布の研究が進んだ結果，地震の多発地域は２次元的な帯状分布という概念より３次元的な〈地震の巣〉という言葉で表現したほうがよいという意見が強い。
