A 7.1-magnitude earthquake rocked the southern coast of Japan on Thursday, Aug. 8, prompting the country to issue its first “megaquake” warning. ... (JMA) in a news release. ...
Following the earthquake, the Japan Meteorological Agency (JMA) issued a 'Nankai Trough Earthquake Extra Information' advisory [28] that the probability of a megathrust earthquake along the Nankai Trough increased from a 0.1% per week to 1% chance [29] in what was the first advisory of its kind but clarified that it was not imminent.
The JMA scale is expressed in levels of seismic intensity from 0 to 7 in a manner similar to that of the Mercalli intensity scale, which is not commonly used in Japan.The JMA uses seismic intensity meters to automatically calculate peak ground acceleration in real-time, reporting intensities based on measurements from observation points.
The Japan Meteorological Agency (JMA) officially named this earthquake the 2024 Noto Peninsula earthquake (Japanese: 令和6年能登半島地震, Hepburn: Reiwa 6-nen Noto-hantō Jishin). [6] It led to Japan's first major tsunami warning since the 2011 Tōhoku earthquake , [ 7 ] and a tsunami of 7.45 m (24 ft) was measured along the Sea of ...
A powerful earthquake measuring magnitude 7.1 struck southwestern Japan on Thursday, triggering tsunami warnings for a number of the country’s western islands and causing mostly minor injuries ...
The Japan Meteorological Agency said the quake registered magnitude 7.1 and was centered in waters off the eastern coast of Japan's southern main island of Kyushu at a depth of about 30 kilometers ...
TOKYO (Reuters) -An earthquake with a magnitude of 7.1 hit southwestern Japan on Thursday, triggering tsunami advisories, the Japan Meteorological Agency (JMA) said, but there were no immediate ...
In Japan, for shallow (depth < 60 km) earthquakes within 600 km, the Japanese Meteorological Agency calculates [2] a magnitude labeled MJMA, M JMA, or M J. (These should not be confused with moment magnitudes JMA calculates, which are labeled M w (JMA) or M (JMA) , nor with the Shindo intensity scale .)
