These have resulted in reconciling differences between dates from documents and materials such as ice-cores and tree rings.
Fusa Miyake gained her doctorate from Nagoya University in 2013 and was then appointed as an assistant professor.
[1] Her doctoral research identified events in the wood of long-lived Japanese cedar trees, now called Miyake events, where there are sudden increases in cosmogenic isotopes such as radioactive carbon isotope 14C, 10Be and 36Cl produced by cosmic rays originating from the Sun when large solar flares or eruptions occur.
Some may be from multiple solar flares, influenced by tree physiology or by interactions of high energy particles with the Earth's magnetic field.
These include: In 2017 Miyake received an Commendation Award for Young Scientists from the Japanese Minister of Education, Culture, Sports, Science and Technology.
