A 5.0-magnitude earthquake rattled Baja California and San Diego County at 3:52 a.m. today. The quake was centered about 20 miles south-southeast of Guadalupe Victoria, according to the U.S. Geological Survey.
It's the same region where a 7.2-magnitude earthquake struck on Easter of this year, and officials say Tuesday morning's quake is likely an aftershock to that event.
There were no immediate reports of damage or injury.
