Tsunami alert after major earthquake rocks Panama

The earthquake occurred in south-central Panama, near the small town of Pitaloza Arriba. USGS placed its epicenter 10 kilometers, or 6.2 miles, from the town. The epicenter is the point on Earth’s surface directly above where the earthquake began. Its location matters because nearby communities usually experience the strongest shaking.

USGS detected the earthquake at 5:56 p.m. GMT on Friday. The quake was initially measured at magnitude 8, then reported as magnitude 7.7. It occurred at a shallow depth of 12 kilometers, which could make shaking more damaging near the surface.

The earthquake was felt across Panama, a country of around 4.5 million people. In Panama City, about 200 kilometers from the epicenter, AFP witnessed people leaving buildings. Several large aftershocks followed, including one measured at magnitude 6.

The earthquake was extremely powerful. USGS initially measured it at magnitude 8, while the later reported magnitude was 7.7. Magnitude describes an earthquake’s size and released energy. A quake near magnitude 8 can produce severe shaking and widespread damage, especially close to its epicenter.

The earthquake began at a depth of 12 kilometers, or 7.5 miles. That is shallow enough for much of its energy to reach the surface strongly. The epicenter was 10 kilometers from Pitaloza Arriba, in south-central Panama. This placed nearby communities at particular risk.

The shaking was felt throughout Panama, a country with around 4.5 million people. It also caused panic in Panama City, about 200 kilometers away. Several large aftershocks were recorded, including a magnitude 6 tremor, adding to the danger after the main shock.

A tsunami warning is an official alert that potentially dangerous tsunami waves may reach coastal areas. It tells people near the shore to take the threat seriously and follow evacuation instructions. The warning does not necessarily mean that damaging waves have already arrived. It signals a credible risk that requires quick action.

Undersea earthquakes can trigger tsunamis when they suddenly move the seafloor. That movement displaces a large volume of water, sending waves outward across the ocean. Coastal earthquakes can also prompt warnings when their location, depth, or movement could affect nearby water. The exact tsunami risk depends on the quake’s underwater movement and other conditions.

The U.S. Tsunami Warning System said waves up to three meters, or 10 feet, could reach Panama’s coastline in the coming hours. The article does not state whether those waves arrived. The warning mattered because coastal residents had limited time to respond.

The earthquake created two immediate hazards: strong ground shaking and a possible tsunami. Extensive damage was expected, particularly in central Panama, although the article reported no casualties at that time. Damage could affect buildings, roads, utilities, and other structures, but the article does not identify specific damaged sites.

The U.S. Tsunami Warning System warned that waves up to three meters, or 10 feet, could hit Panama’s coastline in the coming hours. Such waves could flood low-lying coastal areas and threaten people near the shore. The article gives a possible wave height, not a confirmed outcome.

In Panama City, around 200 kilometers from the epicenter, AFP witnessed people being evacuated from buildings. Several large aftershocks, including a magnitude 6 tremor, added continuing risk. Authorities and residents therefore faced both immediate shaking dangers and the possibility of later coastal flooding.

Shallow earthquakes occur close to Earth’s surface. Their seismic energy travels through less rock before reaching buildings, roads, and people. Because less energy is lost along that short path, nearby areas can experience intense shaking. That can increase the chance of structural damage and falling objects.

This Panama earthquake was recorded at a depth of 12 kilometers, or 7.5 miles. The article specifically notes that its shallow depth meant the impact was likely to be more severe. Its epicenter was also just 10 kilometers from Pitaloza Arriba, placing that town near the strongest effects.

Depth is only one part of earthquake damage. Magnitude, distance from the epicenter, building strength, ground conditions, and aftershocks also matter. In this case, the shallow depth helped explain why extensive damage was expected, particularly in central Panama, even though the article had not yet reported casualties.

Aftershocks are earthquakes that happen after a larger main earthquake in the same general area. They occur as the surrounding rocks adjust to changes caused by the main shock. Most are smaller, but some can still be strong enough to damage buildings or injure people.

Panama recorded several large aftershocks after the main earthquake, including one with a magnitude of 6. A magnitude 6 tremor can produce dangerous shaking, especially near the epicenter or where structures have already been weakened. People leaving buildings may also face falling debris or unsafe streets.

Aftershocks can continue threatening communities even after the first emergency. They can worsen existing damage and complicate inspections, rescues, and evacuations. The article reports no casualties yet, but it expected extensive damage, particularly in central Panama. The continuing aftershocks meant the danger had not ended with the main quake.

Tectonic plates are huge sections of Earth’s outer shell that move slowly. Where plates push, pull, or slide past one another, rocks along faults can become locked. Stress then builds until the rocks suddenly slip, releasing energy as seismic waves. That sudden release produces an earthquake.

Across Central America, plate movement commonly involves the oceanic Cocos Plate moving beneath the Caribbean Plate. Panama also has a complex setting with local faults and nearby plate forces. However, the article does not identify the fault, plate boundary, or exact movement responsible for this earthquake. That specific cause therefore cannot be determined from the source.

The article notes that earthquakes are rare in Panama and usually strike western Chiriqui province. This event occurred in south-central Panama instead. Its unusual location, shallow depth, strong magnitude, and aftershocks help explain the concern, while geological studies would be needed to identify the precise tectonic mechanism.
