An earthquake of magnitude 5.9 has struck about 90 kilometres west of Luwuk in Sulawesi, Indonesia, the European-Mediterranean Seismological Centre says.
The quake on Monday was at a depth of 15km, it says.
On Saturday, an earthquake of magnitude 6.7 has struck south of the Philippines capital, the Philippine Institute of Volcanology and Seismology says.
The agency said aftershocks were expected from the tectonic earthquake, which struck early on Saturday and had a depth of 116 kilometres.
Some residents in the capital region were awakened by the quake that lasted nearly a minute.
"The quake was deep so there is no tsunami," Renato Solidum, director of the Seismology agency, told DZRH radio station.
