On Monday at roughly 1:52 p.m. local time, a 5.9‑magnitude earthquake struck off the coast of Ibaraki Prefecture, northeast of Tokyo, according to the Japan Meteorological Agency. The tremor, measuring about 10 km below the surface, produced seismic‑intensity rating of 3 in parts of Miyagi, Ibaraki, Fukushima and Tochigi prefectures, and shaking was felt in Tokyo.
The agency noted that no tsunami warning was issued, as the quake’s shallow depth and inland proximity made a significant tsunami unlikely.
A Facebook post from a user claims the earthquake occurred around 2 a.m. local time and was a 5.9‑magnitude event, occurring approximately 43 miles underground and injuring 37 people. That report is not corroborated by the Japan Meteorological Agency or other available sources.
