An earthquake hit the southern tip of California this morning and was felt in cities up to 90 miles away.
The 5.3 magnitude quake was part of a wave of reported Imperial County earthquakes, according to the United States Geological Survey.
Although clusters of earthquakes are not uncommon near this region, the strength of the earthquake was considered moderate. This particular group of tremors appears to have included at least 25 individual earthquakes, including the 5.3 magnitude tremor.
The epicenter of the earthquake was located near the town of Calipatria, about 35 miles from the US-Mexico border.

The Imperial Valley swarm enlarged to include earthquakes of M5.3 and 24 M3 +. Until now. The main fault appears to be the NE trending Westmoreland fault. And an introduction to the swarms in episode 19 at: https://t.co/JaAGw80u64

Seismologist Dr Lucy Jones has said in a series of tweets that the 5.3 magnitude quake is expected to be the largest of the swarm and is generally not predictive of future mega quakes. Jones said, “As long as [the swarm] stay active there will be more earthquakes and some could be significant. Most swarms have an ~ M5 as the largest. Rarely do they grow to include an M5.8-6.0.
