The Philippines and some regions of Indonesia have issued a tsunami warning urging coastal communities to evacuate after a magnitude 7.4 earthquake struck offshore in the southern Philippines

The strong quake struck at a depth of 23 kilometres (14 miles) at 9:43 am local time on Friday, according to the US National Tsunami Warning Centre.

The centre warned the earthquake could trigger waves of up to 1 to 3 metres above tide level along the coast of the Philippines, and waves of 0.3 to 1 metres above tide level in parts of Indonesia and Palau.

The Philippine Institute of Volcanology and Seismology “strongly advised” people living in coastal communities in the southern and central Philippines to evacuate to higher ground, as waves of more than 1 metre were expected to hit the area.

President Ferdinand Marcos Jr — popularly known as Bongbong Marcos — said that the Philippines government was “assessing the situation on the ground and ensuring that everyone is safe.”

“I have directed the National Disaster Risk Reduction and Management Council, the Office of Civil Defense, the Armed Forces, the Philippine Coast Guard, and all concerned agencies to immediately carry out evacuations in coastal areas, activate emergency communication lines, and coordinate closely with local governments,” Marcos said, according to the Inquirer, a leading media organisation in the Philippines.

Indonesia’s northern Sulawesi and Papua regions also issued tsunami warnings that waves as high as 50 cm could hit coastal areas, according to Reuters.

There were no immediate reports of casualties in the Philippines following the earthquake, but videos shared on social media show damage to infrastructure.

The US National Tsunami Warning Centre said that tsunami waves can persist for many hours after the first wave hits, and the impact will vary depending on the shape and elevation of the local shoreline.
