Japan Meteorological Agency (JMA)

The Japan Meteorological Agency (JMA) is a governmental organization responsible for providing weather forecasts and warnings in Japan. It plays a crucial role in monitoring seismic activity and issuing tsunami alerts to protect the population from natural disasters. The JMA is newsworthy due to recent strong earthquakes impacting Japan's northeastern region. In December 2025, a magnitude 6.7 earthquake off the coast of Aomori Prefecture prompted a tsunami advisory. Shortly after, a more powerful magnitude 7.6 earthquake triggered tsunami warnings for Hokkaido, Aomori, and Iwate prefectures, with potential tsunami heights reaching up to 3 meters. The JMA reported a 40cm tsunami observed at Mutsu Ogawara and Urakawa ports. These events highlight the JMA's critical role in disaster preparedness and response, emphasizing its significance in safeguarding lives and property in a seismically active region.
