The deadliest earthquake in over a decade has killed 126 people and injured 700 in northwestern China, leaving rescue teams scrambling to reach survivors in freezing weather conditions.

The 6.2-magnitude earthquake struck at 11.59pm (4pm GMT) on Monday, the China Earthquake Networks Centre said, as residents in Gansu and neighbouring Qinghai provinces were sleeping or preparing to sleep.

It was followed by a second 5.5 magnitude earthquake hours later in neighbouring Xinjiang.

The earthquake triggered landslides and wrecked roads and infrastructure, snapping away communication, electricity and water lines in the region.

Thousands of survivors and rescue workers are bracing for a second night of sub-zero temperature as efforts to find missing people and survivors from the rubble ran into the evening.

A magnitude 6.9 earthquake struck off the coast of the southern Philippines, following a series of strong quakes in the same area. Early morning on Monday, the 6.9 magnitude earthquake jolted the southern Philippines early Monday, the United States Geological Survey said.

Yesterday, a magnitude 6.6 earthquake and a deadly magnitude 7.6 quake Saturday struck in the same region.

At least two people were killed and several were injured after Saturday's quake, according to AFP news agency.

Saturday's quake triggered tsunami warnings across the Pacific region and sent residents along the east coast of Mindanao fleeing buildings, evacuating a hospital, and seeking higher ground.
