Yesterday (19th) around 8:40 pm, a magnitude 4.6 earthquake occurred in the sea 144 km east of Ulsan.
Although it is known that there is no damage yet, large-scale earthquakes are occurring all over the world recently, so it seems necessary to analyze the cause.

Last night at about 8:40, an earthquake with a magnitude of 4.6 occurred 144 km from the sea area of Dong-gu, Ulsan.
The earthquake occurred 10 km underground.
Although it is closer to the Japanese side, tremors of magnitude 2 were detected in Ulsan, Gyeongbuk, Busan, and Daegu.
Seismic intensity 2 is the level at which people indoors feel the shaking and hanging objects, such as light fixtures, shake.
It is expected that there will be no damage to the inland area because it is far away and occurs in the sea area.
The Korea Meteorological Administration said there is no risk of a tsunami in Korean waters due to the earthquake.
Korea Hydro & Nuclear Power said that nuclear power plants, such as Shin-Kori Unit 3, are operating normally without any abnormalities.
This earthquake is the most powerful earthquake that occurred in the waters near Korea this year.
In April, a magnitude 3.4 earthquake occurred 23km east of Yeongdeok, North Gyeongsang Province, but this is the first earthquake with a magnitude greater than 4 this year.
On the 18th, a very powerful earthquake with a magnitude of 6.8 occurred in Taiwan and a magnitude 6.1 earthquake occurred in the waters west of Okinawa, Japan, raising tensions over the risk of an earthquake in East Asia.
On the 5th, a 6.8-magnitude earthquake struck Sichuan Province in southwestern China, killing 93 people and leaving 25 missing.
