Tsunami hits South Korea with unexpected 67cm wave, North Korea on alert

South Korea has been hit by a tsunami with a wave height of 67 centimetres, exceeding initial predictions by the Korean Meteorological Administration (KMA). The surging wave height, which is potentially dangerous, could also affect North Korea, which has issued a tsunami warning.

The KMA reported that a 20-centimetre high tsunami wave hit the east coast of Kangneung City in Gangwon province at 6.01pm today, local time, or 4.01pm Thai time. In addition, Donghae city in Gangwon province experienced a tsunami wave reaching 45 centimetres at 4.05pm Thai time.

Furthermore, a 67-centimetre high tsunami wave hit the Makho area of Donghae city at 6pm Thai time today, which is higher than KMA’s previous estimate that the wave would be less than 50 centimetres.

The KMA emphasised that the height of the tsunami wave could reach dangerous levels depending on the rise and flow of the current. The tsunami could impact Gangwon province for more than 24 hours.

Earlier, the authorities in Gangwon province sent a tsunami warning message to residents in six coastal cities and districts, asking them to evacuate to higher ground for safety.

North Korea has also issued a tsunami warning for its east coast following a 7.6 magnitude earthquake in Japan. The Yonhap news agency reported, citing data from North Korean radio, that a wave up to 2.08 metres high could hit the coast.

In related news, the Japan Meteorological Agency issued a high-alert warning for severe earthquakes in the central region next week, following a 7.6 magnitude quake off Japan’s coastline. Ishikawa Prefecture experienced a 1.2-meter tsunami wave, heightening concerns.

The agency urged heightened vigilance among residents, emphasizing the ongoing risk of substantial seismic activity along the western coastline. Stay informed and prepared for potential earthquakes during the forthcoming week as authorities closely monitor the situation for any increased seismic threats.
