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.

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.

Australia has cancelled its tsunami watch after the earthquake in the Philippines.
The Joint Australian Tsunami Warning Centre had initially warned there was a “potential tsunami threat" Christmas Island and Northern Territory.
Meanwhile New Zealand authorities say "the initial assessment is that the earthquake is unlikely to have caused a tsunami that will pose a threat to New Zealand".
At least one person has been killed and four injured after the quake, AFP news agency reports, citing a police official in General Santos City.
Master Sergeant Robert Dagon says "a number of buildings collapsed" but he is unsure how many as they are "busy with ongoing rescues".

Its members are "assessing structural damage" and coordinating evacuation and relief operations, the group says in a post on social media.
General Santos, one of the areas worst-hit by today's earthquake, is known as the country's tuna capital, because of the southern port city's bountiful supplies of the fish.
It is also known as the hometown of Manny Pacquiao, the world boxing champion who was later elected congressman and senator.
Multiple aftershocks - at least 16 of them - have been recorded since the initial quake that struck off the coast of the southern Philippines at 07:37 local time (23:37 GMT).
These range from magnitudes of 1.3 to 6.7, according to the Philippine Institute of Volcanology and Seismology.
Now emerging on social media are videos and images of the quake's devastation in General Santos, the southern Philippine city close to the epicentre.
Videos taken by locals and shared by Philippine authorities show damaged shopfronts and at least two Jollibee restaurants - a beloved national fast food chain - collapsing during the tremor.
