At around 3:00 PM today, three loud explosions were suddenly heard. The main urban areas such as Yubei, Jiangbei and Nan'an all heard the sound. Some citizens thought that another earthquake had occurred. Some people even found that the doors and windows of their houses shook violently, so they ran out of their homes to take cover. Subsequently, when the reporter called the city's Seismological Bureau, relevant personnel confirmed that this was not an earthquake and said that it might be the sound of blasting.
