The first two UTC days of Türkiye’s February 2023 earthquake sequence
The U.S. Geological Survey recorded a magnitude 7.8 earthquake on 6 February 2023, followed about nine hours later by a magnitude 7.5 event. The map and table show larger catalogue records within a fixed area.

Focus a point for its label and magnitude. The table also includes a nearby overlapping event.
The two largest events occurred hours apart
The catalogue places the magnitude 7.8 Pazarcık earthquake at 01:17 UTC and the magnitude 7.5 Elbistan earthquake at 10:24 UTC on 6 February. USGS describes the second as a large aftershock roughly 60 miles away. The map shows their different locations. Source 1 Source 2
Larger catalogue events followed within minutes
The magnitude 6.7 entry at 01:28 UTC followed the first large earthquake by roughly 11 minutes. The table keeps each event’s ID, time and coordinates. The map omits one nearby event to keep its markers readable. Source 1 Source 2
The count depends on the window and threshold
The catalogue query selects a rectangle and the two UTC dates 6 and 7 February, with a minimum magnitude of 5.5. Ten records met those filters on the check date. The search excludes smaller earthquakes and those outside the bounds. Source 1 Source 3
An epicentre is a location plotted on the surface
The coordinates and depth are the catalogue’s estimates. The table keeps depth and magnitude separate. A map point does not show the full extent of fault rupture or shaking. Source 1 Source 2
