What factors of japans geography contributed to the nuclear accident?

Japan's geography, characterized by its location along the Pacific Ring of Fire, makes it prone to frequent earthquakes and tsunamis. The 2011 Fukushima Daiichi nuclear disaster was precipitated by a massive earthquake that triggered a tsunami, overwhelming the plant's defenses. Additionally, Japan's mountainous terrain limits the availability of flat land for safe nuclear plant construction, sometimes necessitating the placement of facilities in vulnerable coastal areas. These geographical factors heightened the risk and impact of the disaster.
