On October 9 in Tokyo, the Japan Meteorological Agency (JMA) issued tsunami advisories for multiple locations following two earthquakes that shook the Izu Islands and Wakayama prefecture.

As per the JMA, the potential tsunami could reach a height of one meter in the Izu Islands, Ogasawara Islands, as well as in the Kochi, Chiba, Miyazaki, and Kagoshima prefectures, as reported by Xinhua news agency.

These advisories, which represent the lowest level in the country's three-tier tsunami warning system, urged individuals to avoid coastlines and rivers while remaining vigilant for possible flooding.

At 5:25 a.m. on Monday morning, an earthquake struck near the Izu Islands at a very shallow depth, as stated by the JMA, without specifying the magnitude of the temblor.

About two hours later, a 3.5-magnitude earthquake rattled the northern Wakayama prefecture.

According to the JMA, the earthquake occurred at 8:18 a.m. at a depth of 70 km, with a latitude of 34.1 degrees north and a longitude of 135.5 degrees east, measuring 2 on Japan's seismic intensity scale, which peaks at 7."
