The reviewed event record
The event has the identifier igepn2026tvmk. The record consulted places it 4.21 kilometers from Samborondón, at coordinates 1.930° south and 79.705° west. Its status is listed as reviewed, with an update logged at 22:26:01 local time on October 9.
Why the initial depth changed
The official IG-EPN channel first released a preliminary location with a depth of 20 kilometers. It later published a revision that keeps the magnitude at 3.6 and puts the depth at about 74 kilometers. The catalog gives the figure more precisely: 73.6 kilometers. In this edition we use the revision, not the first estimate.
The difference between the two records makes it necessary to check the time and status of the record before sharing a screenshot. It does not by itself represent two different events: both posts correspond to the same identifier.
An event separate from the Panama earthquake
The Samborondón record corresponds to an event in Guayas, with its own time and location. There is no evidence in the sources consulted to call it an aftershock of the Panamanian earthquake. Two events occurring on the same day does not demonstrate a causal relationship.
This note documents a seismic measurement; it does not establish damage or people affected, because the records consulted do not provide an assessment of consequences. Nor does it provide evidence of specific impacts in Milagro or Guayaquil.
