SEOUL - Tsunami from strong quakes hitting Japan would affect a part of South Korea's eastern coast, the South Korean weather agency said Monday.

The tsunami was expected to arrive in South Korea's eastern coastal cities, including Gangneung at about 6:29 pm local time (0929 GMT), Yangyang at about 6:32 pm, Goseong at about 6:48 pm, and Pohang at around 7:17 pm, according to the Korea Meteorological Administration (KMA).

The tsunami height was estimated at between 0.2 meters and 0.3 meters when it reaches the coastal cities.

The KMA said a part of the coast in the eastern Gangwon province would see higher sea level due to the earthquake and tsunami from Japan, noting that the tsunami height could be higher than estimated when it arrives in the coast.

A series of strong earthquakes with major ones measured at up to 7.6 magnitude have struck Ishikawa Prefecture on Japan's western coast earlier in the day, with tsunami warnings issued.
