Guatemala’s Seismic Landscape
Three tectonic plates meet beneath and around Guatemala: the Caribbean Plate, the Cocos Plate, and the North American Plate. USGS Professional Paper 1002, the agency’s report on the 1976 earthquake, ties the region’s complex tectonics to this Caribbean-Cocos-North American triple junction.
The Motagua Fault and Subduction Zone
The most prominent geological feature is the Motagua Fault, part of the fault system that USGS says bisects Guatemala from east to west, along the Río Motagua valley. USGS describes the Motagua fault zone as the active boundary between the North American and Caribbean plates, and the 1976 earthquake as left-lateral strike-slip movement on it. The USGS event page for this quake (text abridged from the Earthquake Information Bulletin, July-August 1976) puts the death toll at more than 23,000, while USGS Professional Paper 1002 gives 22,868 deaths as of March 3, 1976 and 1.07 million people left homeless, figures it credits to Guatemala’s Comité Nacional de Emergencia.
To the south, the Cocos Plate is thrust beneath the Caribbean Plate. The same USGS report names this subduction zone as the earthquake source with the highest level of seismicity in Guatemala; the other two are a shallow zone along the chain of active volcanoes and the east-west fault system. INSIVUMEH’s director described the July 17, 2026 mainshock as a product of subduction between the Cocos and Caribbean plates. Guatemala’s volcanoes include Fuego, Pacaya and Santiaguito.
Why This Tracker Matters
This tracker pulls data from the USGS Earthquake Hazards Program and displays the earthquakes of magnitude 2.5 or greater that USGS catalogued within Guatemala and the surrounding region over the past 30 days. You can filter by magnitude, explore earthquake locations on the interactive map, and review historical patterns. For the quakes within 50 km of Antigua Guatemala and the city’s own record back to 1541, see earthquakes near Antigua Guatemala.
For a deeper look at how seismic risk varies by region and what precautions to take, see our comprehensive Guatemala Safety Guide. After a strong quake near the coast, the latest message from the Pacific Tsunami Warning Center, and whether it names Guatemala, is on our tsunami warning page. You can also explore seismic risk data on our interactive department map, which includes safety scores for all 22 departments. Volcanic activity is tracked separately — earthquakes here are tectonic, not eruption signals — on our live volcano tracker with current INSIVUMEH alert levels for Fuego, Pacaya, and Santiaguito, and day by day on volcano eruption status today. What an eruption leaves in the air is a different hazard again: volcanic ash advisories and ashfall safety, and air quality by city.
Emergency Preparedness
Guatemala’s national disaster agency CONRED (Coordinadora Nacional para la Reduccion de Desastres) coordinates earthquake response. Every household should have an emergency kit, know evacuation routes, and practice the Drop, Cover, and Hold On protocol. Keep emergency numbers saved: CONRED 119, Bomberos 122, Cruz Roja 125 (CONRED’s emergency-numbers page). If you feel shaking, stay calm.
