According to El Tiempo, the Colombian Geological Service had counted 184 aftershocks since the August 10 earthquake as of 7:00 a.m. on August 14. The official catalogue also documents five events between 3:44 and 8:28 a.m.; SGC does not label them aftershocks in those records.

A count with a 7:00 a.m. cutoff

Of the 184 reported aftershocks, 15 were above magnitude 3.0 and two were above magnitude 4.0. The total is retained with its reference time and does not automatically incorporate events published or occurring later.

Three events before the cutoff

SGC’s manual catalogue places a shallow magnitude 3.1 event in Sipí at 3:44 a.m.; a magnitude 3.2 event at a depth of 89 km in San José del Palmar at 5:01 a.m.; and a magnitude 3.0 event at a depth of 58 km in El Litoral del San Juán at 5:45 a.m.

Two events after 7:00 a.m.

Two more records list a shallow magnitude 3.2 event in Istmina at 8:08 a.m. and a magnitude 3.1 event at a depth of 57 km offshore in the Pacific at 8:28 a.m. Because they occurred after the cutoff, they are not added to the count of 184.

No damage assessment in these records

The consulted bulletins publish no damage attributed to these five events. The absence of a damage assessment does not by itself prove there were no effects. Any link with the main sequence would require an explicit SGC classification.
