We are now up to four earthquakes in a week in North Texas.
The latest happened just south of Keene on Friday afternoon. It registered at just 2.3 magnitude and there were no reports of damage, but it's the third one in Johnson County since last Saturday.
The fourth quake in North Texas hit near Corsicana.
Last Sunday's 3.6 magnitude quake just northwest of Alvarado was the strongest of the swarm, triggering 911 from across Johnson county.
Nobody was hurt, but that quake was big enough to rattle windows and cause some minor damage.
