At least 19 people have died after a magnitude-7.8 earthquake struck the southern Philippines, according to civil defence officials.

Here's what we've covered today:

• The earthquake struck off the southern island of Mindanao
• At least 134 people have been injured, according to a civil defence office spokesperson - these numbers have to be finally verified by the National Disaster Risk Reduction and Management Council.
• The quake triggered tsunami warnings in the Philippines, Indonesia and Japan. Limited waves ranging from a few centimetres to 1.4m (4.6ft) were later observed. Australia and New Zealand also issued tsunami warnings soon after the quake struck but lifted them soon after
• Videos and images show buildings, including a Jollibee restaurant, being reduced to rubble
• The quake coincided with the start of the new school year in the Philippines. Classes in quake-hit areas been suspended, Philippine President Bongbong Marcos said
• The city of General Santos, near the quake's epicentre, is known as the country's tuna capital
• Evacuation and relief efforts are underway. President Marcos says the government "will not leave Mindanao behind", while the Philippine Red Cross says it's on the "highest alert"

The death toll from the quake has risen to 19, according to a spokesperson from the Philippine civil defence office.

The fatalities will need to still need to be verified and validated by the official disaster agency, they cautioned.

There are also seven people missing, the spokesperson said.

The number of injured now stands at 134.

Earthquakes are common in the Philippines, which sits on the geologically unstable Pacific Ring of Fire.

While most of these quakes pass relatively peacefully, some can prove to be deadly.

Last September, a magnitude-6.9 earthquake struck the central Visayas region, killing more than 70 people.

Days later another eight people were killed when two powerful earthquakes struck off the coast of Davao Oriental in Mindanao.

The earthquake happened in one of the Philippines most seismically active regions, according to government scientists.

The affected provinces face the Cotabato Trench, a "major earthquake-generating structure", according to the Philippine Institute of Vulcanology and Seismology.

The trench is capable of generating minor to great earthquakes, Phivolcs says.

This morning, a "subduction" occured along the trench, Phivolcs says. This happens when one tectonic plate slides beneath another plate.

The earthquake was also felt in Indonesia's North Sulawesi province, more than 200km (124mi) away from the epicentre.

The UK's Foreign, Commonwealth & Development Office (FCDO) has issued safety guidance for the Mindanao region after the earthquake.

If you're in the affected area, follow the advice of local authorities and avoid damaged buildings, the FCDO says.

And if you're planning to travel to Mindanao, contact your travel provider for updates and ensure your travel insurance covers natural disasters, it adds.

The death toll from the magnitude-7.8 earthquake now stands at 15, according to officials from the Philippine Office of Civil Defense.

According to local civil defence office director Rodrigo Sosmeña, 12 of the fatalities were reported in Soccsksargen - a region spanning four provinces and one city: South Cotabato, Sultan Kudarat, Sarangani, and General Santos City.

At least 129 people were reportedly injured in the region, he added.

More than two dozen buildings, many of them commercial establishments, have been damaged by the magnitude 7.8 earthquake in the southern Philippines.

The earthquake struck as the new school year began in the Philippines.

Videos posted on social media showed young students screaming in fear as the ground shook violently. Teachers were seen hugging young children and trying to keep them calm.

Buildings have collapsed, and casualties are feared after a 7.8-magnitude earthquake struck off the Philippines' southern tip at 07:37 on Monday (23:37 GMT Sunday).

If you're just joining us, here's what to know:

• The quake struck off the coast of General Santos City, located on Mindanao, the Philippines' main southern island
• At least three people have been confirmed dead and five others are injured, police say

• Videos and images show buildings collapsing. In this one, a Jollibee fast food restaurant crumbles to the ground
• Tsunami warnings were issued in several countries, from the Philippines to Indonesia, Japan and Australia. Some of those warnings have been lifted now
• Tsunami waves ranging from 3cm (0.1ft) to 0.8m (2.7ft) were recorded in Palau, Indonesia and the Philippine region of Davao, according to the US Geological Survey
• Authorities urged residents to immediately evacuate to higher ground. "Do not wait. Your life is more important than anything left behind," Philippine President Marcos warned

Tsunami waves have been recorded in six areas of Mindanao, according to the Philippine Institute of Volcanology and Seismology.

The affected areas are mostly along Mindanao's southern coast.

The waves were observed between 07:42 and 08:45 local time (23:42 to 00:45 GMT). The highest of the recorded waves measured 1.4m (4.6ft).

The tsunami warning for the Philippines remains in place, the agency told reporters.

Since the initial magnitude-7.8 earthquake struck off the Philippines' southern coast, 138 aftershocks have been recorded as of 11:00 local time (03:00 GMT), according to the Philippine Institute of Volcanology and Seismology.

The magnitudes of these aftershocks range from 1.3 to 6.7.

Police have confirmed that the earthquake has killed at least three people and injured five others.

They estimate that the quake also damaged 37 buildings, mostly commercial.

Philippine authorities say tsunami warnings remain in force as waves are still being recorded following a 7.8M earthquake that struck the south of the country.

“We will not yet lift the tsunami warning as our instruments are still recording tsunami waves. There were also sea level disturbances that were recorded,” Winchelle Ian Sevilla, a science research specialist at the state vulcanology agency has told local outlet ONE News.

The waves measured "a couple of centimetres" in height, he adds.

A tsunami warning issued earlier by Indonesian authorities has been lifted.

As we reported earlier, tsunami waves measuring 0.3ft (9cm) and 2.7ft (0.8m) were observed in Northern Sulawesi province.

The magnitude 7.8 earthquake struck this morning off the Philippines main southern island of Mindanao, causing buildings to collapse and triggering tsunami warnings in some countries.

The earthquake was felt as far away as Davao City, nearly 200km from the epicentre. Below are some photos taken from the city, showing people fleeing for safety.

As we reported earlier, the USGS said a tsunami measuring 1.5ft (0.5m) was recorded in Davao.

We are seeing reports of deaths, however these have yet to be confirmed officially.

Authorities are verifying at least five reported deaths, Reuters reports.

A police official has told AFP that at least one person has died and four are injured.

Diego Mariano, an information officer from the Philippine national disaster agency, says reports of casualties are being monitored.

There has also been reports of major damage across various infrastructure, he says.

He warns the public to avoid re-entering their homes or other buildings, especially those with signs of damage.

Tsunami waves have been recorded in Palau, Davao in the Philippines and Northern Sulawesi province in Indonesia, according to the US Geological Survey.

The waves in two areas of Palau measured 0.1ft (3cm). In two locations in Northern Sulawesi, the waves measured 0.3ft (9cm) and 2.7ft (0.8m). As for Davao, a 1.5ft (0.5m) wave was recorded.

Meanwhile, a tsunami advisory issued earlier for Guam and Northern Mariana Islands has been cancelled, the USGS said in an update.

A resident of General Santos city captured this dramatic video of the quake destroying a building housing a branch of popular Philippines fast food chain Jollibee.
