Police in Bat Xat District surveyed the risks of landslides in the area during Typhoon Yagi and identified the school as high-risk.
On the morning of September 8, all 11 teachers and 131 students were evacuated from the school dormitories to shelter at a local nursery school. That night, the hillside behind the school suddenly collapsed, demolishing 16 of the school's dormitories.
