Magnitude 6.6 Earthquake Strikes Near Río Grande, Panama

A magnitude 6.6 earthquake struck western Panama today, centered about 14 kilometers west of Río Grande, in Coclé Province, at a shallow depth of roughly 10 kilometers, according to the USGS. Shallow quakes of this size are capable of causing significant damage, particularly to older or unreinforced buildings near the epicenter.

Residents in Río Grande and surrounding communities would have felt strong to very strong shaking lasting several seconds — enough to topple unsecured furniture, crack walls, and knock items off shelves. Shaking likely weakened with distance, but people across much of central Panama may have felt noticeable trembling. Panama City, the nearest major population center at about 256 kilometers away with roughly 1.7 million residents, likely experienced light to moderate shaking — enough to be felt, especially on upper floors of tall buildings, but not typically damaging at that distance.

This area has been seismically active: this is at least the 13th earthquake of magnitude 5.0 or greater within roughly 300 kilometers of this location in the past year. That pattern reflects Panama’s position along active tectonic boundaries where the Caribbean, Cocos, and Nazca plates interact.

What to watch for

Aftershocks: A quake of this size is almost always followed by aftershocks, some potentially strong, over the coming hours to days. If you are in the affected area, stay out of visibly damaged buildings until they are inspected.

Aftershock safety: If shaking starts again, drop, cover, and hold on. Outdoors, move away from buildings, walls, and power lines.

Local infrastructure: Check on water, power, and road conditions locally before traveling near the epicentral area. Authorities may issue guidance on damaged structures or closures.

Officials and the USGS will continue updating magnitude, depth, and impact assessments as more data arrives.

Data for this alert comes from the U.S. Geological Survey (USGS) earthquake monitoring network.

Frequently Asked Questions

Was it felt in Panama City?
Likely yes as light to moderate shaking, since the capital is about 256 km from the epicenter. At that distance, damage is unlikely, but high-rise residents may have noticed swaying.

Is a tsunami possible?
The epicenter is on land about 14 km west of Río Grande, so a significant tsunami is not expected. Always follow official local guidance if you are near the coast and felt strong shaking.

Are aftershocks likely?
Yes. A magnitude 6.6 earthquake is typically followed by aftershocks that can continue for days or weeks, and a few may be strong enough to cause additional damage to weakened structures.

Is this quake unusual for Panama?
Not entirely — Panama sits near active tectonic plate boundaries, and at least 12 other magnitude 5.0+ quakes have occurred within about 300 km of this spot in the past year. Still, a magnitude 6.6 is a strong event capable of real damage near the epicenter.

Reported Impact

6 people have reported feeling this quake to USGS’s “Did You Feel It?” system so far; the maximum reported shaking intensity is 4.5 on the Community Decimal Intensity scale; USGS flagged this event as having tsunami potential – check official tsunami warning centers for your region.

Impact figures are from USGS as of when this alert was generated and can rise as more reports come in – this is not a final damage assessment.
