A 3.9-magnitude earthquake struck near Lake Elsinore, prompting over 2,300 people to report feeling the tremor, followed by a 3.0-magnitude aftershock just minutes later.
Magnitude measures the energy released at the source of the earthquake; the U.S. Geological Survey details how quakes between 2.5 and 5.4 are often felt but rarely cause damage.
Experts advise that in the event of an earthquake, people should protect themselves immediately depending on their location, such as pulling over if in a car or staying indoors.
California is prone to earthquakes, but even minor ones can lead to widespread feelings of anxiety, as showcased by a flurry of posts on social media following the tremors.
