Panama Hit by 7.7 Magnitude Earthquake on October 9; Aftershocks Continue

A 7.7 magnitude earthquake struck southern Panama on October 9 at 12:56 P.M. local time, initially measured at 8.0 by the U.S. Geological Survey before being downgraded. The quake hit nine miles southwest of Pitaloza Arriba in Herrera Province, affecting approximately 4.6 million people with moderate to severe shaking. Structural damage was reported across central provinces, with 147 aftershocks recorded, some reaching magnitudes of 6.1 to 6.6. Officials reported several injuries but no immediate fatalities.

Damage concentrated in central provinces

The most significant damage occurred in Coclé, Veraguas, Herrera, and Los Santos provinces on Panama’s southern coast. In Penonomé, about 70 miles from the epicenter, a church steeple partially collapsed and multiple buildings sustained structural damage. A multi-story building in the resort town Playa Venao collapsed and crushed several cars. The cathedral in Penonomé’s main square cracked, and the Church of San Atanasio in Los Santos province collapsed. Panama City’s two metro lines suspended service and evacuated passengers from some stations.

Panama Canal operations continue with inspections underway

The canal authority reported that operations were continuing as normal despite the earthquake. The Centennial Bridge’s suspension cables were seen shaking as vehicles crossed. Staff were inspecting facilities for damage. The Emergency Operations Center director René García told CNN that authorities were waiting for tremors to subside before conducting structural inspections of damaged buildings.

Tsunami warning lifted as quake struck on land

The U.S. National Oceanic and Atmospheric Administration initially warned of potential tsunami threats across Costa Rica, El Salvador, Peru, Mexico, Guatemala, Nicaragua, Colombia, and Ecuador. However, the alert was lifted by Friday afternoon. USGS seismologist Susan Hough explained that because the quake occurred on land at a shallow depth of 21 miles, it did not move the seafloor beneath the water column needed to generate a tsunami. USGS modeling estimated likely casualties in the range of dozens to hundreds of fatalities and damages in the hundreds of millions of dollars.

Regional context amid recent seismic activity

Panama’s earthquake follows a series of devastating tremors across Latin America. In June, two back-to-back earthquakes measuring 7.2 and 7.5 magnitudes struck Venezuela’s La Guaira state, killing more than 6,500 people and leaving 17,000 homeless. In August, a 7.4 magnitude earthquake in Colombia killed at least 289 people. President José Raúl Mulino called for calm on social media, writing that the earthquake should not be used to cause alarm or disorder.

Final Thoughts

Panama’s 7.7 magnitude earthquake caused significant structural damage across central provinces but avoided major loss of life so far. The canal continues operating normally, and officials are assessing damage as aftershocks subside. Regional seismic activity remains elevated.
