A felt earthquake refers to an earthquake whose magnitude is greater than 3 and less than 4.5, and people feel it, but it does not directly cause serious injuries or deaths or heavy property losses. Simply put, it is an earthquake that people can feel.

Microseism refers to earthquakes with magnitude greater than or equal to 1 and less than magnitude 3. This kind of earthquake is imperceptible to people and can only be detected by instruments.

At about 14: 45 pm, residents of Xianggeliyuan Community, Xiang Qiao Road, Futian District said that they obviously felt the building shaking, and the whole process only took one or two seconds.

Yang Yueming, deputy director, told the reporter that a 3.5-magnitude earthquake occurred on Dangan Island in the Pearl River Estuary, which only caused a felt earthquake in most parts of Shenzhen. It is understood that the focal length from Shenzhen is 60 kilometers. This is a major earthquake in Shenzhen since the 1999 Dapeng Bay earthquake. He said that at present, the instruments of seismic stations are not advanced enough to predict all earthquakes, but once an earthquake occurs, they can know it immediately. As for whether there are aftershocks, it is still inconclusive.

In addition, Yang Yueming, deputy director of the Seismological Station, told the reporter that after the earthquake, the telephone on duty at the Seismological Station kept ringing.
