東京･赤塚の崖 ｜ 東京23区最大の崖は､なぜ赤塚に？ 武蔵野台地と荒川低地の境界線

Itabashi Ward, Tokyo, is home to the largest cliffs in the 23 wards, with a height difference of about 20m. We will walk through the area where the Musashino Plateau, formed by the accumulation of volcanic ash from Mt. Fuji and Mt. Hakone, borders the Arakawa River, and see how the cliffs were formed. 🌟Membership registration    / @chiri_rider   ★Website "Listen to the voice of the contour lines!" http://chiririder.com/ ★Geographic Rider's Twitter (Follow now)   / chiri_rider   ★Question box (For questions and requests that are not directly related to the video, please go here) https://peing.net/ja/chiri_rider Source of geological map: AIST Geological Survey of Japan "1:200,000 Seamless Geological Map of Japan v2" https://gbank.gsj.jp/seamless/v2.html
