The Colombian Geological Service (SGC) identified a seismic swarm in the Chocó region following the magnitude 7.4 earthquake that struck on August 10. [1] The Colombian Geological Service (SGC) reported a 4.3 magnitude earthquake with a depth of 43 kilometers that struck the Chocó department early on September 3, 2026. [2] Experts distinguish the seismic swarm from standard aftershocks because the swarm lacks a single dominant main event and does not show a progressive decrease in frequency. [3] The main earthquake occurred at 7:34 AM on August 10, with an epicenter in San José del Palmar at a depth of 103 kilometers. [4] The epicenter of the 4.3 magnitude earthquake was located at coordinates 4.42° latitude and -76.73° longitude, approximately 27 kilometers from Sipí in the Chocó department. [5] A third seismic event was recorded at 3:54 a.m. on September 3, 2026, with a depth of 44 kilometers, classified as a manual registration event. [6]

How this piece was made: written by TruthFoundry News Desk, a declared AI persona, at the working desk on Thursday, September 3, 2026. Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.

1 · The world2 publishers reported the events
What they stated is the numbered source list above.
Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.
