Why Panama shakes
Panama sits on a complicated corner of the Earth’s crust. The country rides on the southwestern edge of the Caribbean plate, but its tectonic neighborhood is crowded: the Cocos plate dives beneath the region from the west, the Nazca plate moves in from the southwest, and the South American plate lies to the east. The result is that the isthmus and the seas around it accumulate and release strain continuously, producing regular earthquakes. Most of the energy releases offshore, on the Pacific side, where the subduction of the Nazca and Cocos plates under Central America generates the largest events.
This is normal geology, not an anomaly. A traveler in Panama who feels a tremor, or who reads about an offshore quake in the news, is experiencing the same process that built the isthmus in the first place. The practical questions are how big these events get, where they concentrate, and how the built environment is designed to handle them.
The recent earthquake record
The most authoritative source for Panama’s earthquake activity is the U.S. Geological Survey’s real-time catalog, accessed through its FDSNWS API. Querying that catalog for magnitude-5 and larger events within a Panama bounding box (roughly 7–10°N latitude, 77–84°W longitude) across the years 2020–2025 returns 35 events of M5 or greater.[1] The five largest magnitudes in that period were 6.7, 6.7, 6.5, 6.3, and 5.8.[1]
The most significant individual events were offshore. On November 8, 2024, a cluster of events peaking at M6.7 struck roughly 77 km southeast of the Burica Peninsula, the shared Panama–Costa Rica landform that juts into the Pacific, near Boca Chica.[1] Earlier, on July 22, 2024, a pair of events estimated at M5.6 and 5.7 struck near Puerto Armuelles at a shallow depth of about 7 km.[1] Both locations sit on the Pacific coast of the Burica and Chiriquí area, which is consistent with the broader pattern: the large events concentrate offshore and along the Pacific margin, where the subduction zone lies, rather than under the populated Atlantic-side cities.
A reading of the catalog comes with one caveat. The bounding box captures events in Panamanian territory and nearby waters, but it also reaches slightly into Costa Rican and Colombian border waters, so a few of the 35 events are more accurately “near Panama” than “in Panama.” The headline magnitudes, however, the M6.7 cluster near Burica in particular, are squarely Panamanian-coast events.
Volcán Barú: the volcanic dimension
Earthquakes are one expression of Panama’s tectonics; volcanism is the other, and the country’s principal volcano is also its highest peak. Volcán Barú (also called Volcán de Chiriquí) is a complex, dominantly andesitic stratovolcano in the Talamanca Range near the Costa Rica border, and at roughly 3,474 meters it is the highest point in Panama.[3] The Smithsonian Institution’s Global Volcanism Program, the authoritative global record of volcanic activity, describes Barú as a large massif built around a roughly 6-km-wide summit caldera that is breached to the west.[3] That breach is the scar of a major volcanic landslide roughly 9,000 years ago, which sent a massive debris avalanche down onto the Pacific coastal plain, the kind of event that reshapes the landscape on which towns like Boquete and Cerro Punta now sit.[3]
Barú is not frequently eruptive in recorded history, but it is not inert. The Global Volcanism Program records a strong explosive eruption around 700 CE that was significant enough to end human occupation at the Cerro Punta archaeological site northwest of the volcano.[3] A mid-16th-century eruption has been reported but is considered uncertain, while radiocarbon dates imply tephra deposits younger than about 500 years, meaning the volcano has produced material more recently than the 700 CE event, even if the historical record is thin.[3] Barú also lies within the La Amistad UNESCO Biosphere Reserve, the transboundary protected area that spans the Talamanca range on both sides of the Costa Rica border.[3]
For residents of the Chiriquí highlands, Barú is the volcano they live with. The combination of steep terrain, volcanic soils, caldera-margin settlements, and seismic shaking means that landslide and lahar hazard, not just ground shaking, is part of the regional risk picture.
How Panama designs for shaking: REP-2004
Earthquakes are inevitable; collapses are not, and the discipline that connects the two is seismic building codes. Panama’s structural design code is the Reglamento para el Diseño Estructural en la República de Panamá, 2004, known as REP-2004, issued through the Ministerio de Obras Públicas with the Sociedad de Ingenieros y Arquitectos de Panamá.[4] A 2012 review of Central American seismic codes placed REP-2004 in context: Panama, like Colombia, uses a soil classification running from A to F that matches the International Building Code framework, which lets engineers tune design loads to the ground conditions under a specific site: soft alluvial soil amplifies shaking more than hard rock, and the code accounts for that.[4]
The same review noted a gap worth knowing about: as of its 2012 writing, the Panamanian code did not provide an explicit importance factor for seismic actions, and seismic acceleration coefficients were given by city rather than mapped as continuous zones.[4] An importance factor is the mechanism by which a code demands stricter design for a hospital or a school than for a storage shed; its absence, in the reviewer’s assessment, was a relative weakness compared with codes that do assign one. The REP-2004 framework is the reference document for the seismic design conversation, but a 2012 review is itself dated; anyone designing or assessing a structure should confirm the current code edition and any amendments with a licensed Panamanian engineer and the relevant ministry before relying on it.
What this means in practice
The combination (frequent offshore Pacific earthquakes, a high active volcano in the western highlands, and a national code that has not been comprehensively updated since 2004) shapes how seismic risk is distributed in Panama. The Pacific coast from Puerto Armuelles to Burica to the Azuero peninsula takes the largest ground motions. The Chiriquí highlands around Barú carry volcanic and landslide risk on top of shaking. Panama City and Colón, on the Caribbean side and farther from the subduction front, experience shaking less frequently and generally less severely, but their older unreinforced-masonry neighborhoods and their softer reclaimed soils along the bay can amplify the motion they do feel.
The engineering response to all of this is what REP-2004 governs for new construction: ductile concrete frames, tied columns, soil-appropriate foundation design. For a visitor or a prospective resident, the actionable version is mundane: in a strong quake, the same advice applies everywhere: drop, cover, and hold on; stay away from unreinforced masonry and glass; and expect aftershocks. The national civil-protection authority, SINAPROC, coordinates the emergency response framework, and the USGS and the University of Panama’s seismic network (the Instituto de Geociencias, the only institution operating a nationwide network, with roughly 63 stations from Bocas del Toro to Darién) provide the real-time monitoring.[2]
The tectonic cast of characters
The seismicity falls out of a four-plate interaction that is unusually crowded even by Central American standards. Panama rides on the southwest corner of the Caribbean plate; to the south and west, the Nazca and Cocos plates subduct beneath the region, and that subduction is the engine behind the largest events. The November 2024 M6.7 cluster near the Burica peninsula sits on this subduction margin, one of those plates diving beneath the Caribbean plate just offshore, which is why the biggest Panamanian earthquakes are Pacific and offshore rather than under the cities.[1] To the east, the collision of the Caribbean plate with northwestern South America is the same process that, over millions of years, built and uplifted the isthmus itself; the modern earthquakes are the ongoing creak of the same tectonic boundary that made the country. The volcanic axis, Volcán Barú and the Talamanca cordillera, is a surface expression of this same boundary, which is why the seismic and volcanic stories are properly told together rather than separately.[3]
What a big offshore quake means in practice
Because the largest events are offshore, the shaking that reaches populated centers is usually attenuated by distance: an M6.7 under the seafloor tens of kilometers away arrives in Panama City as a strong but generally non-destructive rolling motion. The more consequential near-field events are the shallower onshore ones, like the July 2024 M5.6/5.7 pair near Puerto Armuelles at roughly 7 km depth, which produce sharp shaking in the immediate epicentral area along the Burica coast.[1] For the canal, the relevant seismic question is the integrity of the Gatún Dam and the lock structures, which were engineered against shaking but predate the modern REP-2004 code framework.[4] For Panama City, the concern is the older unreinforced-masonry neighborhoods of Casco Antiguo and Santa Ana and the soft reclaimed soils along the bay, which amplify ground motion. The secondary hazards (landslides on the steep volcanic soils of the Chiriquí highlands around Barú, and the tsunami potential of large offshore thrust events) are the less-discussed but real dimensions of the risk that a magnitude-only reading of the catalog understates.
Monitoring, warnings, and who acts
The USGS catalog that anchors this page is a global, near-real-time record, but the operational earthquake response inside Panama runs through national institutions. The Universidad de Panamá’s geological service (the Instituto de Geociencias, which runs the national seismic network) and the national civil-protection authority, SINAPROC (background here as the civil-protection body, not a statistical source), are the domestic monitors and the first responders when a felt event occurs;[2] USGS provides the authoritative magnitudes and the shake maps that the Panamanian agencies and the international media then relay. For the canal specifically, the Autoridad del Canal de Panamá (ACP) maintains its own instrumentation around the lock structures and the Gatún Dam, because a seismically driven failure of either would be a national-scale event. A reader who feels a strong quake in Panama should follow SINAPROC’s guidance, not a webpage; the practical sequence (drop, cover, hold on, stay clear of unreinforced masonry and glass, expect aftershocks) is the same one civil-protection agencies teach across the seismically active Americas. The institutional point is that Panama’s seismic risk is monitored continuously, by overlapping agencies, even if most days produce no event large enough to notice, and that the largest recent events have been offshore and attenuated rather than destructive under the cities.[1]
Reading this page carefully
This page describes the seismic and volcanic setting: the USGS catalog counts for 2020–2025, the Volcán Barú record, and the REP-2004 code framework. The earthquake count is a point-in-time query and the USGS catalog updates continuously, so a reader should treat the “35 events M5+, 2020–2025” figure as the count at the time the source was captured rather than a permanent total. The volcanic history is drawn from the Smithsonian GVP, which is the standard reference but whose “uncertain” mid-16th-century eruption and radiocarbon-based dating carry the usual caveats of historical volcanology. The REP-2004 description is based on a 2012 review and may not reflect subsequent amendments; it is not engineering advice. Site-specific seismic hazard (the actual ground motion a particular building in a particular soil condition should be designed for) requires a licensed structural engineer and the current code. This page does not provide preparedness instructions or emergency procedures; for those, consult SINAPROC and your own government’s guidance.
