Small tsunami waves were recorded in the Izu island chain near Tokyo and other areas of Japan's Pacific Coast on Monday following a nearby earthquake, according to the country's weather agency, with no damage or injuries reported.
Tsunami up to 60 centimeters in height were measured at Hachijo and some other islands in Izu, as well as an island in the Ogasawara chain in the Pacific Ocean, south of Tokyo. There were waves of 30 cm recorded in Tateyama, Chiba Prefecture, and 40 cm in both Tosashimizu, Kochi Prefecture, and Nakano Island in Kagoshima Prefecture, after advisories were issued for the areas. All the advisories were lifted at noon.
After the tsunami alert, five coastal cities in Kochi and 12 municipalities in Chiba issued a directive for residents to evacuate.
The epicenter of the 5:25 a.m. quake was at a shallow depth in waters near the uninhabited Torishima Island at the southern end of the Izu chain, but further details including the magnitude of the tremor remained unclear, the Meteorological Agency said.
The agency predicted a 1-meter tsunami for Chiba. Tsunami measuring 20 cm were also observed in Nichinan, Miyazaki Prefecture.
Local authorities said there have so far been no reports of injuries or damage on the islands nor in Chiba, Kochi, Kagoshima or Miyazaki.
Several small boats in Hachijo and Kozu islands, part of the Izu chain, had overturned but no injuries were reported.
Last Thursday, small tsunami waves arrived in parts of the Izu island chain following an earthquake with a magnitude of 6.5 in the Pacific Ocean.
