A 6.8 magnitude earthquake struck today on the island of Mindanao, south of the Philippines with a 28.2 km deep epicenter, according to the US Geological Survey.

The area affected by the quake was 61 km southwest of Davao City, Philippines. The Pacific Tsunami Warning Center said that based on current data, the quake poses no tsunami threat.

No damage has been reported, however, earthquakes of such magnitude can damage buildings. Meanwhile, the US Geological Survey (USGS) predicts "low probability of casualties and damage".

Several people have posted on Twitter videos showing the earthquake caused power lines to explode, sparks to splash or water to spill from a neighborhood swimming pool.

The Philippines is located on the Pacific "Ring of Fire", which has many geological activities and frequently experiences earthquakes and volcanic disasters.

At the end of October, Mindanao island also suffered two earthquakes in a row. At least 8 people were killed and more than 300 were injured due to a 6.6 magnitude earthquake on October 29. The 6.5 magnitude earthquake on October 31 was thought to be aftershocks, causing a major hotel to collapse.
