An earthquake, also known as a quake, tremor or temblor, is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.

The US Geological Survey says on its website the magnitude of the quake was 5.0.

The earthquake’s epicentre was 80 kilometres from Tongliao city, close to the border of Liaoning province, and the depth of the hypocentre was six kilometres, according to China Earthquake Network Centre.

The quake jolted the northern province a little past 5pm, causing tremors in multiple locations in nearby Liaoning and Jilin provinces, the Centre said.
