At 1:28 am today, a 3.7 magnitude earthquake occurred in the sea area 25 km west of Ganghwa Island.
The depth of occurrence was found to be 19 km under the sea.
It has been two months since the magnitude 4.1 earthquake that occurred in Goesan, North Chungcheong Province on October 29 last year that an earthquake of magnitude 3.5 or higher occurred.
In the metropolitan area, it was the strongest earthquake in four years since 2019.
The instrument seismogram, which is the degree of shaking, was up to 4 in Incheon, 3 in Gyeonggi, and 2 in Seoul.
Instrument seismic intensity 4 refers to the degree to which many people feel indoors, wake up at night, and shake dishes and windows.
According to the earthquake early warning system, an emergency disaster text message was sent to the metropolitan area within a radius of 80 km from the epicenter within 9 seconds of the earthquake.
If your smartphone is temporarily connected to a communication network other than 4G or 5G, or if you have rejected emergency text messages, you may not have received the text message.
Immediately after the earthquake, the system stopped at one point as surprised citizens flocked to the Naver portal news site.
Experts cautioned against possible aftershocks.
[Hahm In-gyeong/Seismic Analyst, Korea Meteorological Administration: In general, small-scale aftershocks can last for several days even for earthquakes of magnitude 4 or less.]
In the case of the Goesan earthquake in Chungcheongbuk-do, 144 aftershocks occurred in nearby areas for 12 days. .
