カルデラ湖の内壁と外壁の違いは？
この穏やかな十和田湖が、実は火山活動の産物であることをご存知でしたか？十和田湖はカルデラ湖と呼ばれ、火山の噴火で陥没した窪地に水が溜まってできました。カルデラの内側の斜面はとても急で、湖面からの高さは平均して300～400メートルですが、600メートルの高さまで切り立った部分もあります。一方、カルデラの外壁をなすのは放射状に広がるなだらかな斜面です。山頂から湖の眺めを楽しみ、多様性豊かな景色を注意深く観察しましょう。

What Is the Difference Between the Inner and Outer Walls of the Caldera Volcanic Lake?
Did you know that peaceful Lake Towada is the result of volcanic activity? The lake is a caldera lake, meaning that its waters sit in an empty chamber left in the collapse after a volcanic eruption. The inner slope of the caldera is steep—climbing sharply to a height of up to 600 meters above the lake’s surface, with an average height between 300 to 400 meters. In contrast, the caldera’s outer wall consists of a gentle slope that extends outwards in all directions. Enjoy surveying the varied landscape and make note of these differences while viewing the lake from the ridge.
