A moderate earthquake, measuring 5.7, struck the Philippines on Thursday, according to the United States Geological Survey.
The quake occurred at 7:39 a.m. Philippine time, about 6 km southeast of Liloan, Philippines, according to agency data.
As seismologists review the available data, they may revise the reported magnitude of the earthquake. Additional information collected about the earthquake could also prompt USGS scientists to update the shaking severity map.
Aftershocks in the region
An aftershock is usually a smaller earthquake that follows a larger earthquake in the same general area. Aftershocks are usually minor adjustments along the part of a fault that slipped during the initial earthquake.
Earthquakes and aftershocks within 100 miles
Aftershocks can occur days, weeks, or even years after the first earthquake. These events can be of equal or greater magnitude than the initial earthquake, and they can continue to affect already damaged sites.

When aftershock data is available, corresponding maps and diagrams include earthquakes within 100 miles and seven days after the initial earthquake. All times above are Philippines times. Shake data is as of Wednesday, January 22 at 7:12 p.m. Eastern Time. Aftershock data is as of Thursday, January 23 at 4:25 a.m. Eastern Time.
