A moderate-magnitude 5.7 earthquake struck the Pacific Ocean off the coast of Panama on Monday, according to the U.S. Geological Survey.
The quake struck about 3 miles southeast of Puerto Armuelles, Panama, at 2:19 p.m. Panamanian time, according to the agency.
As seismologists review available data, they may revise the reported magnitude of an earthquake. Additional information collected about an earthquake may prompt USGS scientists to update their seismic intensity maps.
Aftershocks in the area
An aftershock is a small earthquake that usually follows a larger earthquake in the same general area. An aftershock is usually a minor adjustment along a part of a fault that slipped during the initial earthquake.
Earthquake and aftershocks within 100 miles
Aftershocks can occur days, weeks, or even years after the initial earthquake. These events can be as large or larger than the initial earthquake and can continue to affect areas that have already been affected.

When aftershock data is available, the maps and charts include earthquakes within 100 miles of the initial earthquake and within 7 days of the initial earthquake. All times above are Panama time. The earthquake data is as of 3:43 p.m. ET on Monday, July 22. The aftershock data is as of 8:04 p.m. ET on Monday, July 22.
