Japan Meteorological Agency (JMA)

The Japan Meteorological Agency (JMA) is Japan's national meteorological service, responsible for providing weather forecasts and warnings related to natural disasters like earthquakes and tsunamis. It plays a crucial role in public safety by monitoring seismic activity and issuing timely alerts to mitigate potential damage. The JMA is newsworthy due to recent significant earthquakes off the coast of northeastern Japan. Specifically, a magnitude 6.7 earthquake on December 12, 2025, and a magnitude 7.6 earthquake on December 8, 2025, triggered tsunami warnings issued by the JMA. These warnings prompted evacuation orders in affected prefectures, including Hokkaido, Aomori, and Iwate. The JMA's observations of tsunami waves at various ports, such as Mutsu Ogawara and Urakawa, further highlight its critical role in tracking and communicating the immediate impact of these natural disasters, emphasizing its significance in disaster preparedness and response.
