On the 30th, a magnitude 8.7 earthquake struck the Kamchatka Peninsula in Russia, prompting the Japan Meteorological Agency to issue tsunami warnings and advisories. It is expected that there will be little impact on Korea.
A spokesperson from the Korea Meteorological Administration noted, "About 5 hours (around 1:30 p.m.) after the earthquake, there may be a slight rise in water levels near Ulleungdo," adding, "It seems that there will be little impact domestically."
However, the situation may change depending on whether additional earthquakes occur. On that day, following the magnitude 8.7 earthquake which struck around 8:24 a.m., aftershocks of magnitude 6.9 and 6.3 occurred around 9:09 a.m. and 9:16 a.m., respectively.
The Japan Meteorological Agency issued a tsunami advisory for the Pacific coastal regions from Hokkaido to Kyushu, and upgraded it to a tsunami warning for eastern Japan around 9:40 a.m. The expected height of the tsunami has also increased from 1 meter to 3 meters.
