[Asia Economy Reporter Lee Ji-eun] In the early morning of the 9th, a magnitude 3.7 earthquake occurred off the coast of Ganghwa-do, Incheon, and small aftershocks are expected to continue for the next few days. There is also an analysis that if this earthquake is a 'foreshock' rather than the 'main shock,' a larger earthquake could occur.

Park Soon-cheon, head of the Earthquake and Volcano Research Division at the Korea Meteorological Administration, said on MBC's "Kim Jong-bae's Focus" in the morning, regarding the possibility of aftershocks, "As of 7 a.m., one aftershock of magnitude 1.2 has occurred," adding, "Generally, for earthquakes below magnitude 4, small aftershocks can continue for several days."

Earthquakes are classified into foreshocks, main shocks, and aftershocks, with the main shock being the largest in magnitude. Authorities are currently considering the early morning magnitude 3.7 earthquake as the main shock. Park said, "As of now, it is considered the main shock," but added, "However, in some cases, a larger earthquake may occur, in which case that earthquake would be the main shock, and this one would be the foreshock."

So far, no specific damage reports have been filed, but 104 earthquake detection reports have been received from Seoul, Incheon, Gyeonggi, and Gangwon. Park said, "Although relatively large earthquakes have occurred several times, there is no need to be overly anxious," adding, "However, the Korean Peninsula experiences various earthquakes of different sizes due to crustal activity in multiple regions." This means the Korean Peninsula is not a 'seismically safe zone.'
