西新山沼和舊國道230號線 / Nishi Shinzan Numa and the former route 230

西新山沼和舊國道230號線（洞爺湖町）是2000年有珠山噴發時的受災地之一，現在變成了著名觀光景點。當時的國道230號被破壞到已經不可能恢復原狀的程度，因此轉移到不同的地點。陷下去的道路聚集了水變成了沼澤。可以觀察到隨著火山活動造成大地變動的樣子。

Nishi Shinzan Numa and the former route 230 (Toyako Town) are examples of local infrastructure which sustained damage from the 2000 Mt. Usu eruption. These locations are now transforming into sightseeing spots. The eruption caused some areas of the land to either elevate or collapse. A part of route 230 caved-in and then turned into a big pond, after years of rainfall filled it up. This is Nishi Shinzan Numa. You can learn about the power of volcanic activity at this site. Nishi means western part, and shinzan stands for a new mountain.
