At 17:56 UTC on Friday, 9 October 2026 — 12:56 PM in Panama, 10:56 in the morning Pacific time — a magnitude 7.7 earthquake struck western Panama, 12 km west-southwest of Pitaloza Arriba. USGS lists it as Mww 7.7 at 12.6 km depth, with an epicenter at 7.59°N, 80.77°W, and has marked the event “reviewed.” This is a developing story: the event is only hours old, and the first official damage and casualty assessments are still on the way.
On Tremr's live feed, the early signature reads like a major shallow quake: shallow, no tsunami flag, a PAGER alert still pending with no color assigned, and just 17 felt reports filed so far. The solution is well constrained — 108 reporting stations — and the “reviewed” mark means a USGS analyst has signed off on the magnitude, location, and depth. Nothing in the published data says anything about damage or casualties yet, but for an event this fresh, an absence of reports is not yet a conclusion.
USGS places the epicenter at 7.5868°N, 80.769°W — 12 km west-southwest of Pitaloza Arriba in western Panama. At 12.6 km depth it counts as a shallow earthquake, the depth range where shaking reaches the surface at nearly full strength — and M7.7 is a large event by any measure. Each full unit of magnitude releases about 32 times more energy, so an M7.7 carries roughly 30 times the energy of an M6.7. The “reviewed” status matters: it means a USGS analyst has checked the automated solution, so 7.7 and 12.6 km are the numbers to trust, not placeholders the feed will revise by a full point. A focal mechanism has not been published in the data reviewed, so we don't yet have the official fault geometry.
Depth is doing most of the work here. A 12.6 km M7.7 is the shallow-end member of the family — compare it with an intermediate-depth quake like the 2026 Colombia M7.4 to see how depth rewrites the felt area. For how shaking scales against magnitude, see Magnitude vs Intensity.
Panama sits at one of the most tectonically complicated corners of the Americas. The Ring of Fire framing fits loosely here: Panama is where the Nazca, Cocos, Caribbean, and North American plates all meet and grind past one another, and the Middle America Trench runs offshore of the Pacific coast. Seismologists describe this junction as tectonically complex and very active, regularly subjected to earthquakes above magnitude 7. In other words: M7-class quakes here are not anomalies. They are the region's normal weather.
That complexity is exactly why a shallow M7.7 this close to land gets watched so closely in its first hours. Large, shallow, and near populated coast — it is the combination seismologists worry about most, whatever the eventual damage turns out to be. For the fault geometry behind events like these, see Fault Types Explained.
USGS shows no tsunami flag for this event — no wave has been generated or confirmed. But a shallow 12.6 km M7.7 is the kind of event that can make one, so this is the part of the story most likely to change in the first hour. Panama's own emergency authorities issue their own tsunami guidance; if you are on a low-lying coast and felt long or strong shaking, treat the shaking as the natural warning and move to high ground — don't wait for the feed to catch up. Read How Tsunami Warnings Work.
Expect aftershocks. After an M7.7, sequences typically produce M5- and even M6-class aftershocks in the first days and weeks, occasionally a second large event. Tremr's live feed will track them as they come in.
Felt reports will keep climbing from the current 17; the more “Did You Feel It?” responses USGS receives, the sharper the ShakeMap becomes. If you felt this earthquake, filing a report is one of the genuinely useful things a reader can do — citizen reports are part of how the science improves in real time.
What we don't know yet: there are no official casualty or damage figures in the USGS data at publication time, and we will not fill that silence with guesses. This article will be updated as agencies publish assessments.
Standard shallow-quake drill: Drop, Cover, and Hold On during shaking; stay away from the coast until any advisory is lifted; check on neighbours; keep a radio and charged phone handy. Don't re-enter visibly damaged buildings before the aftershock window closes. The full room-by-room guide is What to Do During an Earthquake, and the 72-Hour Earthquake Preparedness Kit is worth assembling before the next one — because in this neighbourhood, there is always a next one.
A reviewed M7.7 at 12.6 km depth, 12 km from Pitaloza Arriba: shallow enough to rattle a wide area of western Panama, and fresh enough that the main question now is what the aftershocks and the first assessments reveal. Watch the Tremr feed, respect the coast until the all-clear is certain, and treat every shallow M7 as a shaking story first — and, until the reporting window closes, a story that isn't finished.
