The claim
三重県南東沖で起きた地震は人工地震
Original review summary
The review reports that the earthquake off southeastern Mie Prefecture was a natural deep earthquake, not an artificial one. A seismology professor said the waveform matched a normal earthquake; the apparent waveform anomaly came from how the vertical motion was scaled.[S1]
Additional context
The strong shaking observed far from the epicenter is described as an “abnormal seismic intensity” phenomenon, which can occur when waves travel through a rigid oceanic plate with little attenuation. [S1]
