Panama City, Panama — A powerful magnitude 7.7 earthquake struck Panama on Friday afternoon, shaking buildings and sending people rushing outdoors as authorities warned that potentially widespread tsunami waves could threaten coastlines across parts of Central and South America.
The United States Geological Survey (USGS) initially recorded the earthquake at magnitude 8.0 before revising it to magnitude 7.7. The quake occurred at 12:56 p.m. local time on Friday, October 9, with its epicenter reported about 9 miles southwest of Pitaloza Arriba.
The earthquake had an estimated depth of approximately 20.5 miles, according to the agency’s preliminary information.
The full extent of the damage and whether anyone was injured had not been immediately confirmed following the powerful shaking.
Earthquake Shakes Panama as Residents Rush Outside
The strong earthquake was felt in Panama City, where people reportedly rushed outside as the shaking spread through the capital.
The quake’s considerable magnitude raised immediate concerns about possible damage, particularly in areas closer to the epicenter. However, officials had not yet confirmed the extent of structural damage or reported casualties in the immediate aftermath.
The USGS initially listed the earthquake at magnitude 8.0 before lowering the preliminary estimate to 7.7 as seismic information was reviewed.
Earthquake magnitude estimates can change as scientists analyze additional readings from monitoring stations. The initial figures provide an early assessment, but subsequent reviews help determine the event’s characteristics more accurately.
For residents across Panama, the immediate concerns included possible aftershocks, damage to buildings and infrastructure, and the potential effects along the country’s Pacific coastline.
Tsunami Threat Raises Concerns Across Pacific Coastlines
The earthquake prompted a tsunami warning assessment from the National Weather Service’s Pacific Tsunami Warning Center in Honolulu.
Based on the preliminary earthquake information, the center said widespread tsunami waves were possible along the coasts of nine countries.
The areas identified included:
- Panama
- Colombia
- Costa Rica
- Ecuador
- Peru
- Nicaragua
- Guatemala
- El Salvador
- Mexico
The potential reach of tsunami waves made the situation a concern beyond Panama itself, particularly for communities along the Pacific coastline.
Tsunamis can occur when an underwater earthquake displaces a large volume of water. Depending on the earthquake’s location, depth and the movement of the seafloor, resulting waves can travel across ocean basins and affect distant coastal areas.
However, the possibility of tsunami waves does not establish that destructive waves will reach every location listed. The actual effects depend on the characteristics of the earthquake and subsequent tsunami observations.
Officials Continue Assessing the Preliminary Earthquake Data
The magnitude, location and depth of the Panama earthquake were still considered preliminary in the initial reports.
Scientists were expected to review additional seismic data to refine the earthquake’s measurements and better assess the potential tsunami threat.
Such updates are important because tsunami assessments can change as monitoring centers receive more information about an earthquake and evaluate ocean conditions.

People in potentially affected coastal areas should follow official instructions from local emergency management agencies and tsunami warning authorities. Where an evacuation is ordered, residents should move promptly to designated safe areas or higher ground.
The absence of immediately confirmed damage reports does not necessarily mean the earthquake caused no damage. Assessments can take time, particularly when authorities need to inspect buildings, roads and other infrastructure.
Situation Remains Developing After Powerful Quake
The magnitude 7.7 earthquake placed Panama and neighboring Pacific coastal regions on alert as officials assessed the situation.
The immediate priorities were determining whether the quake had caused significant damage, confirming whether injuries had occurred and evaluating the potential for tsunami waves.
The earthquake’s final measurements and the extent of its impacts could become clearer as additional information becomes available.
For now, the event highlights how a powerful earthquake can create concerns well beyond its epicenter, particularly when tsunami risks extend across multiple coastlines.
