Tsunami 40 cm high were observed at Hachijo Island in the Izu chain off Tokyo Wednesday afternoon following an 8.0-magnitude earthquake that rocked the Solomon Islands in the South Pacific, the Meteorological Agency said.
Tsunami about 10-cm high were also observed at Chichijima in the Ogasawara island chain, at Owase in Mie Prefecture, as well as at Kushimoto and Nachikatsuura, both in Wakayama Prefecture, the agency said.
Observation data from other locations along the Pacific coast were mostly within the range of 10 to 20 cm or less.
The Solomon quake prompted the agency to issue a tsunami alert for Japan’s Pacific coast.
At 2:41 p.m., the agency warned that tsunami of up to 50 cm high could reach the Pacific coast between Hokkaido and Okinawa.
The agency urged people to stay away from the shore and warned that the first tsunami is not necessarily the highest if it originated in a distant location.
The powerful earthquake occurred near the Solomon Islands at 12:12 p.m. local time. Tsunami 91 cm high were observed in the Santa Cruz Islands.
