A moderate magnitude 5.7 earthquake struck the Philippines on Thursday, according to the United States Geological Survey.
The quake struck at 7:39 a.m. Philippine time about 4 miles southeast of Liloan, Philippines, the agency said.
As seismologists review available data, they may revise the reported magnitude of the earthquake. Additional information gathered about the earthquake could also prompt USGS scientists to update the earthquake magnitude map.
Aftershocks in the region
An aftershock is usually a smaller earthquake that follows a larger one in the same general area. Aftershocks are usually smaller adjustments along the part of the fault that slipped at the time of 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 can continue to affect already damaged sites.

When aftershock data are available, the corresponding maps and charts include earthquakes within 100 miles and seven days of the initial earthquake. All times listed above are Philippine time. Earthquake data is as of Wednesday, January 22 at 7:12 PM Eastern. Aftershock data is as of Wednesday, January 22 at 11:40 PM Eastern.
