New evidence has emerged which suggests that a major volcanic eruption in 1761 belched out enough dust and gas to completely blot out the moon, thus explaining the missing moon observed that year during a total lunar eclipse. According to a report in National Geographic News, astronomer Kevin D. Pang collected evidence from the fields of geology, biology, and Chinese history to come up with the theory. A good candidate for the cause of the 1761 events is the eruption of Makian volcano on the Indonesian island of Halmahera.
