Strong, shallow underwater earthquakes hit western Indonesia and the Philippines' capital area on Monday, but no significant damage or tsunami warnings were issued.
According to the US Geological Survey, a magnitude-6.7 earthquake with a depth of 16 kilometers struck Indonesia, around 169 kilometers west of Pariaman, a town in West Sumatra province.
The tremor was felt in several regions of the province, according to the Indonesian Meteorology and Geophysics Agency, although there was no threat of a tsunami. It happened around 161 kilometers southeast of South Nias, a district in North Sumatra province, soon before sunrise.
The Philippine Institute of Volcanology and Seismology said that a 6.4-magnitude earthquake jolted areas of the Philippine capital region and outlying provinces around morning, although no damage or casualties were recorded.
The offshore quake was triggered by movement in the Manila Trench, and its epicenter was around 110 kilometers west of Lubang Island in Occidental Mindoro province, which is south of Manila. It was roughly 28 kilometers deep.
Indonesia and the Philippines are located on the Pacific "Ring of Fire," which is a line of seismic faults that runs around the Pacific Ocean, and are regularly impacted by earthquakes and volcanic eruptions.
In total, there are 15 countries that lie in the ring of fire: Indonesia, New Zealand, Papa New Guinea, Philippines, Japan, United States, Chile, Canada, Guatemala, Russia, Peru, Solomon Islands, Mexico, and Antarctica.
Last month, a 6.2 magnitude earthquake struck Indonesia's West Sumatra region, killing at least 16 people and wounding over 400 others. The earthquakes, which were felt as far away as Malaysia and Singapore, destroyed thousands of homes and other structures.
