About Kazuyoshi Z. Nanjo

I graduated from the Institute of Geology and Palaeontology, Tohoku University, Japan, with a PhD. Since then, I have worked in academia and industry in Japan, the US and Switzerland. My work surrounds the probabilities of occurrence and precursory warnings for a range of natural hazards, with an emphasis on earthquakes, volcanoes and tsunamis. Over the last decade, a major discovery has been the application of the concepts of big data to these problems. The holy grail is to have reasonably accurate earthquake forecasts.

How small earthquakes hint at Japan’s next megaquakes

Japan is known for its great earthquakes, but our new study asks what the countless small events can tell us. By treating them as a stress meter, we find different futures for offshore Tohoku and Hokkaido in terms of long-term megaquake hazard.
