Radiocarbon analysis uncovers possible traces of hidden earthquakes off Japan's coast
Phys.org ·
The Brief
- University of Tokyo researchers used a new type of radiocarbon analysis on a sediment core from the Kumano Sea off Japan.
- The analysis revealed multiple possible traces of previously unknown earthquakes in the Nankai Trough.
- The source excerpt is truncated and does not give further details on dates, magnitudes or methods.
Why it matters
It suggests the seismic history of the Nankai Trough, a major fault zone off Japan, may be more complex than previously recorded, which matters for earthquake hazard assessment.

Researchers at the University of Tokyo have used a new type of radiocarbon analysis to study a sediment core taken from the Kumano Sea off the coast of Japan. This has revealed multiple "hidden" traces of previously unknown earthquakes in the Nankai Trough, where the country's…
