Three small earthquakes hit the southeastern coast tonight, raising concerns about the possibility of a larger quake soon hitting the region. According to Yonhap News, a 3.5 magnitude earthquake, centered about 35 kilometers northeast of the southeastern city of Ulsan, struck first at 9:57 p.m.
A second 2.6 magnitude quake stuck seven minutes later, while a third, recorded at 1.9 struck at 10:10 p.m.
