1. The Japanese government panel has revised the probability of a megaquake in the Nankai Trough within 30 years, with estimates ranging from around 60-90% to as low as 20-50%.
2. These revisions were made due to uncertainties found in historical records used for calculations. A margin of error was also factored in the first estimate.
3. Despite the differing estimates, the research committee emphasizes the high imminence of a Nankai Trough megaquake and encourages ongoing disaster-prevention measures. They plan to use the higher range when explaining the quake chances to the public.
