A minor earthquake of magnitude 2.7 was recorded near Moreno Valley, California, on Tuesday, January 13th, 2026, at approximately 1:33 PM local time. This seismic event, while not expected to cause widespread damage, serves as a reminder of the ongoing geological activity in the region. Understanding these events and how to prepare for them is crucial for residents.
Understanding the Moreno Valley Earthquake
Initial reports from the United States Geological Survey (USGS) indicate the quake occurred at a relatively shallow depth of 8.5 miles. Generally, shallower earthquakes are perceived as stronger because the energy has less distance to travel to reach the surface.It’s important to remember that these initial assessments are often refined as more data becomes available.
Seismologists continuously analyze data, and subsequent reports from other agencies, such as The Incorporated Research Institutions for Seismology (IRIS), confirmed a magnitude of 2.7. Interestingly, the European-Mediterranean Seismological Centre (EMSC) measured the quake slightly higher, at a magnitude of 2.8. These slight variations are common in initial readings and highlight the complexity of accurately measuring seismic activity.
Did you know? California experiences an average of 230 earthquakes each year,most of which are too small to be felt.
Impact and Felt Reports
The quake was likely felt as very weak shaking in communities closest to the epicenter. Moreno Valley, with a population of approximately 204,200, is located just 2 miles from where the earthquake originated. Redlands, home to around 71,000 residents, experienced the event approximately 6 miles away.
Further afield, in cities like Colton (pop. 54,600), Riverside (pop. 317,300), San Bernardino (pop. 216,100), Highland (pop.54,900), Perris (pop. 75,000), Rialto (pop. 103,100), and Fontana (pop. 212,700), the shaking was likely imperceptible to most people. The intensity of shaking diminishes with distance from the epicenter, and the magnitude of the quake plays a significant role in how widely it’s felt.
Here’s a quick comparison of the affected areas:
| City | Population (approx.) | Distance from Epicenter | Expected Shaking |
|---|---|---|---|
| Moreno Valley | 204,200 | 2 miles | Very Weak |
| Redlands | 71,000 | 6 miles | Very weak |
| Riverside | 317,300 | 10 miles | Not felt |
If you experienced shaking during this earthquake, reporting your experience is valuable. Your observations help seismologists refine their understanding of the event and improve future assessments.
