A rapid swarm of small earthquakes shook Los Angeles communities near the Newport-Inglewood Fault, reminding residents how fragile daily life can be when the ground itself is unsettled.
Story Snapshot
- United States Geological Survey logged about 90 micro-quakes near Lennox and Westmont, magnitudes 1.0–2.7
- Several quakes also hit nearby areas, including a 2.6 near Westmont and Inglewood
- The swarm clustered along the Newport-Inglewood Fault Zone, which runs through dense neighborhoods
- No major damage reports surfaced as counts shifted across outlets during catalog updates
What Shook And Where It Hit
Los Angeles felt a burst of seismic activity from Friday night into Saturday afternoon. The United States Geological Survey recorded about 90 micro-quakes around unincorporated Lennox and Westmont, with magnitudes from 1.0 to 2.7 during that window. Local stations picked up additional small quakes across Southern California, including a 2.6 near Westmont early Saturday. A separate event near Inglewood, also measured at 2.6, drew two dozen felt reports according to public logs.
Reporters noted the most active cluster sat along the Newport-Inglewood Fault Zone, a strike-slip fault that runs from Culver City to Newport Beach. This fault cuts through busy neighborhoods, older buildings, and key roads. That makes even small shakes a test of readiness for a larger event someday. Several same-day quakes also occurred off Catalina Island, which shows how the whole region can wake up at once during active periods.
Why The Numbers Differ And What That Means
Different outlets listed different totals because catalogs update in real time. One count cited more than 60 events, while others placed the number above 80 or near 90 during overlapping time windows. Seismic networks add, merge, or drop picks as data improves, which can nudge the final tally. That process is normal. It does not change the main fact: many small quakes struck in a short span, and most were too weak to cause damage.
Scientists describe a swarm as many small quakes in one area without a single main shock. The United States Geological Survey explains that swarms can last hours to weeks and often feature many quakes of similar size. A swarm does not mean a big quake will follow, though it can raise short-term interest in monitoring. The safest move for families is simple: update a plan, check supplies, and secure heavy items at home and work.
Risk, Readiness, And The Fault Beneath
The Newport-Inglewood Fault has a long record and runs under high-population zones. Past research and trench work show it has produced notable earthquakes in history. That is why even small clusters near this fault get close attention from scientists and emergency managers. Saturday’s Inglewood-area 2.6, which drew multiple felt reports, was a reminder that shallow, local shakes can wake people despite their modest size.
We have an earthquake swarm currently in process in the Los Angeles Basin. No major quakes yet, but over 100 minor ones in that large cluster. Consider how the massive erosion that struck many SoCal beaches transported tons of sand to new locations and altered mass distribution. pic.twitter.com/kzHx4TQ6LF

For residents, this is a fairness issue as much as a science story. People pay taxes and expect working alerts, sturdy infrastructure, and honest communication. Government at every level should use moments like this to prove it can deliver. Clear updates, fast checks on bridges and utilities, and support for home hardening do not lean left or right. They protect everyone. Small swarms fade, but steady readiness is what keeps families safe when the next test comes.
