A tsunami warning has been issued for parts of the Philippines and Indonesia after a 7.2 magnitude earthquake.
The quake hit Mindanao, in the southern Philippines, and all coasts within 300km of the site are at risk of tsunami waves.
The Indonesian islands of Geme and Tabukan Tengah, and Davao in the Philippines could all experience the damaging waves within the hour.
The Philippine Institute of Volcanology and Seismology has advised people to ‘stay away from the beach and not go to the coast fronting the Philippine Sea between 12pm and 2pm local time, and until the threat has passed'.
The advisory says ‘the first tsunami waves will arrive between 12 and 2pm, and may not be the largest'.
‘These waves could continue for hours'.
Early calculations suggest the waves will be less than a metre above normal levels.
Those living in the cities said on Volcano Discovery they felt their houses shaking and heard rumbling noises.
‘I was watching Bird Box and suddenly I felt dizzy,' a person in Butan City, more than 300km from the epicentre of the quake, wrote. ‘Next thing I know, people are shouting God's name.'
Another person in Maragusan, about 160km from the epicentre, said they saw tremors in the water and objects in their home were shaking.
‘It startled me and my Mom,' they wrote. ‘The chandeliers are shaking, and the waters are shaking too.
‘It was indeed a strong earthquake and thank God, me and my Mom are safe.'
An office building in the Davao City in the Philippines was evacuated, the quake leaving those who were inside petrified and the building itself cracked.
‘It was a very bad experience for us,' the report said.
‘We are [on the] 10th floor of the building that I'm working at and the building is shaking.
‘Everyone is getting panic [sic] and we don't know what to do. Thanks God we are safe… but the building has cracks.'
There is no tsunami threat to Australia.
