A moderate magnitude 5.7 earthquake struck the Philippines on Thursday, according to the United States Geological Survey.
The incident occurred at 7:39 a.m. Philippine time about 4 miles southeast of Lilan, Philippines, according to the agency.
As seismologists review the available data, they may revise the earthquake’s reported magnitude. More information collected about the earthquake could prompt USGS scientists to update the quake-severity map.
Shocks in the region
An aftershock is usually a small earthquake that is larger in the same general area. Aftershocks are typically minor adjustments to the fault segment that slipped during the initial earthquake.
Earthquakes and aftershocks within 100 miles
It can happen days, weeks or years after an earthquake. These events may be equal to or larger than the initial earthquake, and may continue to affect areas that have already been damaged.
