That roughly translates as, “4.6 magnitude earthquake on 2.11 at 5:03 5 km to the northwest of Buk-gu, Pohang City, Gyeongbuk, be careful of aftershocks.”
The magnitude was later adjusted to 4.8.
According to the United States Geological Survey, earthquakes in the 4.0 to 4.9 range are considered light. Conditions may include, "Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably."
