8 Out of 14 Died. That Led to Prison Sentences for Three Teachers The 2017 Nasu Avalanche Accident

This time, we will provide a clear explanation of the 2017 Nasu avalanche accident using topographic maps and animation.
We pray for the repose of the souls of those who lost their lives and wish for the safety of everyone involved in the dangerous and arduous rescue operations. Thank you very much.
(Additional Information) The reason why Mr. C did not allow the Moka High School students to assist in the rescue was that he had not fully grasped the situation immediately after the accident and could not rule out the possibility of a secondary disaster. Therefore, he instructed them to wait in a safe place.
(Correction Information) The recognition of the avalanche occurred immediately after the encounter, not after being buried.
Having experienced firsthand how the lack of knowledge can affect the lives of loved ones, I started this activity with the hope of spreading life-saving knowledge to as many people as possible.
※ Reference information is posted in the pinned comment section.
I strive to faithfully recreate the facts by consulting as many sources as possible for the explanations. Due to various theories about the circumstances of the disaster, some adjustments or omissions may be made for the sake of the explanation, so please understand. ※ The thumbnail image is AI-generated.
I also love mountaineering and map reading, but I have had several near-miss experiences. Fortunately, I did not have to call for rescue, but a single mistake could have cost me my life. Based on these past experiences and reflections, I share this information.
My main job is as a systems engineer, but I devote most of my time to creating these videos, learning unfamiliar tools like Google Earth Pro and Vyond, and writing scripts. The narration is done by someone else, and other parts are created with the help of knowledgeable experts.
