Magnitude 2.6 earthquake in Yesan, South Chungcheong Province… “I felt the apartment shaking.”

On the 25th, a magnitude 2.6 earthquake occurred in Yesan-gun, South Chungcheong Province. The magnitude of the earthquake felt nearby was magnitude 4 (IV), so residents responded, “I was scared because it felt like my apartment was shaking.” The Korea Meteorological Administration announced that a magnitude 2.6 earthquake occurred 2km northwest of Yesan-gun, Chungcheongnam-do on this day. The earthquake occurred at 11:53:35 a.m. and the depth of the earthquake was 8 km. The Korea Meteorological Administration issued an earthquake report at 11:57, about 4 minutes after the earthquake occurred, saying, “Areas near the earthquake may feel shaking,” and urged people to “please be careful about safety.” Regardless of the magnitude of the earthquake, the seismic intensity in South Chungcheong Province on this day was measured at 4 (IV). While ‘earthquake magnitude’ measures the absolute energy of an earthquake, the intensity is a relative number that records the shaking or shock that occurs in a specific area due to an earthquake. The seismic intensity level of 4 (IV), measured this time in the budget, is a level where many people feel the earthquake indoors, wake up at night, and dishes and windows are shaken.
