中央構造線は日本最大の構造線だ。
The Median Tectonic Line is Japan's largest tectonic line.
構造線に沿って温泉が多く分布している。
Many hot springs are distributed along the tectonic line.
地震の多い地域は構造線の近くに位置していることが多い。
Areas with frequent earthquakes are often located near tectonic lines.
A geological term composed of 構造 (structure) and 線 (line). Japan has several major tectonic lines that are important in geography education and earthquake science.
MAJOR JAPANESE TECTONIC LINES:
- 中央構造線: Median Tectonic Line — the longest fault in Japan, running from Kyushu to the Kanto region
- 糸魚川静岡構造線: Itoigawa-Shizuoka Tectonic Line — divides Honshu's geology into eastern and western halves
- 柏崎千葉構造線: Kashiwazaki-Chiba Tectonic Line
COMMON COLLOCATIONS:
- 構造線に沿って: along the tectonic line
- 活構造線: active tectonic line
