The most deaths recorded on Mount Everest in a single day is eight.
According to information from HISTORY.com, eight climbers died on Mount Everest during a storm on May 10, 1996. This event stands as the worst loss of life ever on the mountain on a single day.
This tragic incident was famously documented by author Jon Krakauer, who was present during the climb, in his best-selling book, Into Thin Air, published in 1997. The events of that day highlight the inherent risks involved in climbing the world's highest peak.
The May 10, 1996 disaster involved multiple expeditions caught in a blizzard near the summit. The combination of extreme altitude, severe weather conditions, and logistical challenges contributed to the high fatality rate that day.
