The Philippines has been rocked by a "strong" 7.5 magnitude earthquake, its second major tremor in just days.
The country's Phivolcs seismology agency warned of damage and aftershocks after the strong offshore quake, which struck in waters off Manay town in Davao Oriental in the Mindanao region.
It said the quake - originally a 7.6, but revised down to a 7.5 - happened some six miles below the Earth's surface.
The agency has since recorded a series of much weaker aftershocks, ranging from 2.6 to 4.9 on the Richter scale.
The UK Foreign Office has now told Britons to move to higher ground in the wake of the quake.
In a fresh travel warning, it urges those in the affected area to be aware of the risk of aftershocks, avoid damaged buildings and infrastructure, and follow the advice of local authorities.

President Ferdinand Marcos has said authorities are assessing the situation on the ground, and confirmed search and rescue efforts were being prepared.
"We are working round the clock to ensure that help reaches everyone who needs it," Mr Marcos said.
One official said there were initial reports of damage to homes, buildings and bridges - but no casualties.
The Philippines sits on the so-called Pacific "Ring of Fire" - and experiences more than 800 quakes each year.
On September 30, 72 people died after a 6.9 magnitude earthquake hit Cebu, near the centre of the archipelago.
This year, alongside the Filipino pair of quakes, Russia and Japan's Pacific coasts were rocked by the sixth-largest earthquake in recorded history.
Travel alerts were issued in almost 30 countries following the quake - thought to have been the largest in more than a decade.
