A moderately strong earthquake of 5.7 magnitude struck the Pacific Ocean off the coast of Panama on Monday, according to the U.S. Geological Survey.
The quake struck at 2:19 p.m. Panamanian time about 3 miles southeast of Puerto Amuyes, Panama, according to the agency.
When seismologists review existing data, they may revise the reported magnitude of an earthquake. Gathering more information about earthquakes may also prompt USGS scientists to update earthquake intensity maps.
Aftershocks occurred in the area
Aftershocks are usually smaller earthquakes that follow a larger earthquake in the same area. Aftershocks are typically small adjustments along the portion of the 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 may be the same or larger in magnitude than the original earthquake, and they may continue to impact already damaged sites.
