Small tsunami waves arrived in parts of Japan's Izu island chain following an earthquake with a preliminary magnitude of 6.5 in the Pacific Ocean on Thursday morning, with no damage reported.
The Japan Meteorological Agency issued a tsunami advisory for the island chain after the quake was detected at around 11:00 a.m., predicting 1-meter waves would reach the area. Tsunami waves as high as 30 centimeters were measured at Hachijo Island at 12:17 p.m.
The agency lifted the advisory at 1:15 p.m.
The quake struck off Torishima, an uninhabited island around 580 kilometers south of Tokyo, at a depth of 17 km.
The agency revised the initially reported magnitude of 6.6 and depth of 10 km.
The temblor did not register 1 on the Japanese seismic intensity scale of 7, according to the agency.
The agency warned that the region could be hit by further quakes as seismic activity has continued since earlier this week.
