■ Special Edition Released May 11, 2026
Area: Surrounding the Kanto-Koshin region
Timing: By June 17
Magnitude: M5.5 ± 0.5
【Accurate Prediction of M5.5 Earthquake with Maximum Intensity of 5-Lower】
As a result, an earthquake registering a maximum seismic intensity of 5-lower (magnitude 5.5) occurred on June 16, 2026. JESEA's prediction matched the actual earthquake in terms of location, timing, and magnitude.
This successful prediction was originally published as a 'Pinpoint Prediction' within the weekly 'MEGA Earthquake Prediction' service, but was issued as a special edition bulletin on this occasion.
The 'Pinpoint Prediction' forecasts the occurrence of an earthquake of magnitude 6 or higher within one month at a specific location.
The 'Pinpoint Prediction' leverages JESEA's proprietary advanced technologies, including patented methods, integrating comprehensive analysis of over 10 types of precursory phenomena to enhance prediction accuracy.
In 2024, 23 out of 29 predictions were accurate, achieving a hit rate of 79.3%. In 2025, 18 out of 21 predictions were accurate, achieving a hit rate of 85.7%.
Thus, the 'Pinpoint Prediction' has consistently demonstrated high accuracy in forecasting earthquake occurrences.
We hope this Pinpoint Prediction continues to support disaster preparedness for many people.
