A 6.2 magnitude seismic event rocked Shimane and Tottori prefectures in Japan on Tuesday, prompting immediate checks but no tsunami warning from meteorologists. Local reports detailed the sequence of tremors that disrupted daily life briefly.
The main shock struck eastern Shimane at 10:18 AM local time, achieving upper 5 intensity on Japan’s seismic scale. It was followed by a 5.1 magnitude aftershock at 10:28 AM and a 5.4 at 10:37 AM. The shallow 10 km depth amplified ground shaking in the area.
No harm to people has been noted yet. Matsue’s Shimane Nuclear Power Station officials verified all systems normal post-event. Western Japan’s bullet trains faced stoppages on the Sanyo Shinkansen between Okayama and Hiroshima due to electricity glitches, JR West stated, hoping for 1 PM restarts while other segments see delays.
Recalling a prior 5.7 magnitude quake on December 31 near Iwate at 40.1°N, 142.9°E and 30 km deep—with intensity 4 in Morioka and no tsunami issued—Japan’s vigilance against earthquakes remains critical in this tectonically active zone.
