TOKYO (Web Desk) — A powerful 7.6 magnitude earthquake — measured as the “strongest” on the Japanese scale — rocked Japan on Monday prompting a tsunami warning for a broad swath of the country’s western coast, The Japan Times reported.

The tsunami warning issued by the Japan Meteorological Agency urged people to quickly leave the coastal areas of Ishikawa, Niigata, Toyama and Yamagata prefectures, public broadcaster NHK reported.

Tsunami of up to five metres high are believed to be reaching Noto in Ishikawa Prefecture, according to the weather agency.

Waves more than 1 metre high hit the coast of Wajima City in Ishikawa Prefecture, NHK added.

Hokuriku Electric Power said it is checking for any irregularities at its nuclear power plants, while a spokesperson for Kansai Electric Power said there were currently no abnormalities at its nuclear power plants but the company was monitoring the situation closely.

The quake, which struck on New Year’s Day, was felt in Tokyo and across the Kanto area.

Additionally, after Monday’s earthquake in Japan, South Korea’s meteorological agency also warned of a potential rise in the sea level in some parts of the Gangwon province on the east coast.

Videos shared online showed strong tremors being felt across the Ishikawa prefecture.
