Miyake events: a review of the state-of-the-art
Miyake events are fast and significant radiocarbon rises in the Earth's atmosphere. Japanese researchers from Nagoya University discovered this kind of event based on radiocarbon analysis in tree rings. They found a spike in the radioactive carbon isotope in the ring of 775AD compared to the 77...
