5.1 Magnitude Earthquake Strikes off Guatemala Pacific Coast
A magnitude 5.1 earthquake struck off the Pacific coast of Guatemala on June 21, 2026, at 22:00 local time, and was felt across several regions of the country with no immediate reports of damage or injuries. The Guatemala earthquake registered at 22:00:23 hours according to monitoring systems and produced shaking that reached multiple areas without triggering official damage assessments at the time of reporting.
Event Overview
The earthquake had a preliminary magnitude of 5.1 and occurred at a depth of 44.28 km with its epicenter in the Pacific Ocean at coordinates 13.270 latitude and -90.939 longitude. [2] This event was recorded by the Sección de Sismología del Insivumeh and was felt in several regions of the country. [2] No official reports of material damage or affected persons have been issued as of the latest update. [2] The Guatemala earthquake produced no immediate indications of structural impacts or injuries based on available information from authorities.
Seismic Data and Measurements
The earthquake had a preliminary magnitude of 5.1, occurred at a depth of 44.28 km, with its epicenter in the Pacific Ocean at coordinates 13.270 latitude and -90.939 longitude. [2] Data remain preliminary and subject to change following further analysis by monitoring networks. [2] The event was detected by the systems of Insivumeh at the precise time of 22:00:23 hours on June 21, 2026. [2] These parameters form the core measurements released in the initial bulletin from the agency responsible for seismic monitoring in the region.

Related Seismic Activity
USGS reported two additional earthquakes in the vicinity: a M4.3 event 55 km SSE of Iztapa at a depth of 55.1 km and a M4.7 event 56 km S of Puerto San José at a depth of 45.8 km. [1] [4] These events occurred in the same coastal region and were documented alongside the primary Guatemala earthquake. [1] [4] The presence of multiple recorded tremors underscores the ongoing seismic monitoring conducted by international and national agencies in the area.
Geological Context
Guatemala experiences frequent seismic activity due to its location at the boundary of the Caribbean, Cocos, and North American tectonic plates, as well as the Mesoamerican Trench off its Pacific coast. [2] This tectonic setting places the country in one of the regions with greater seismic activity in Central America. [2] The Mesoamerican Trench generates movements of varying intensity on a regular basis. [2] The Guatemala earthquake fits within this established pattern of constant seismic events, some of which remain barely perceptible while others carry the potential for infrastructure effects.
Official Response and Safety Recommendations
No official reports of material damage or affected persons have been issued as of the latest update. [2] Authorities recommend standard safety measures including identifying evacuation routes, preparing emergency kits, avoiding windows and unstable structures during shaking, and relying only on official information. [2] Additional guidance includes maintaining calm, keeping an emergency backpack with water, non-perishable food, flashlight, radio, batteries and essential medicines, steering clear of falling objects and unstable structures, avoiding elevators, reviewing structural damage before re-entering buildings, and remaining alert to possible aftershocks. [2] These steps reflect the standard prevention measures promoted by civil protection organizations in response to the Guatemala earthquake.

Ongoing Monitoring
The preliminary nature of the data leaves room for updates as additional analysis is completed. [2] Potential for aftershocks remains a factor that residents are advised to monitor through official channels. [2] The Guatemala earthquake bulletin emphasizes the need to follow only information issued by recognized sources and to stay attentive to subsequent developments reported by Insivumeh and related agencies.
What to watch next: Further updates on aftershocks and any revisions to the preliminary magnitude and depth figures for the June 21, 2026 event, along with continued reporting on the additional M4.3 and M4.7 earthquakes noted by USGS in the same coastal zone.
