## Key context

### What is normal within 100 km of Los Angeles

Over the 30 years 1996-2025, USGS recorded 570 earthquakes of M3 or more within 100 km of Los Angeles: about 19 a year, or 1.6 a month. The past 12 months had 23, about 21% more than the 30-year average. Quakes of M6 or more average 0 a year here (0 in 30 years), and none happened in the past 12 months.

Busy years usually mean one large quake and its aftershocks: the peak year here was 1997 with 39. Counts cover a circle with a 100 km (62 mile) radius around downtown Los Angeles, from Ventura County to the Inland Empire and Orange County. They come from the USGS ComCat catalog, which records small quakes more completely in the US than elsewhere, so compare like with like.

| Magnitude | 30-year total | Average per year | Past 12 months |
| --- | --- | --- | --- |
| M3+ | 570 | 19 | 23 |
| M4+ | 71 | 2.4 | none |
| M5+ | 4 | 0.1 | none |
| M6+ | 0 | 0 | none |

| Magnitude | Place (USGS) | Date | Depth |
| --- | --- | --- | --- |
| M6.7 | Northridge, California, earthquake | 1994-01-17 | 18 km |
| M6.6 | 1971 San Fernando Earthquake, California | 1971-02-09 | 9 km |
| M6.4 | The 1933 Long Beach, California Earthquake | 1933-03-11 | 6 km |
| M6.2 | 3 km SE of San Bernardino, California | 1923-07-23 | 5 km |
| M6.0 | The 1910 Lake Elsinore, California Earthquake | 1910-05-15 | 0 km |
| M5.9 | The 1987 Whittier Narrows, California Earthquake | 1987-10-01 | 15 km |
| M5.9 | 1km ENE of Granada Hills, California | 1994-01-17 | 5 km |
| M5.8 | 10km SSW of Agua Dulce, CA | 1971-02-09 | 6 km |

### Plates and faults

Los Angeles sits in the "Big Bend" of the San Andreas Fault, where the fault turns west and the Pacific and North American plates squeeze together instead of only sliding past each other. That squeezing has raised the Transverse Ranges and created thrust faults, some of them hidden under the city (blind thrusts).

The 1994 Northridge quake (M6.7) and the 1987 Whittier Narrows quake (M5.9) came from such thrust faults, not from the San Andreas itself, which runs about 50 km north-east of downtown along the San Gabriel Mountains.

- San Andreas Fault (Mojave segment, about 50 km north-east)
- Puente Hills blind thrust (under downtown)
- Newport-Inglewood Fault (1933 Long Beach, M6.4)
- Hollywood, Santa Monica and Raymond faults
- Sierra Madre Fault (San Gabriel Valley)
- Northridge blind thrust (San Fernando Valley)

### Where the recent quakes were

Of the 6 quakes of the past 30 days, 6 were shallow (less than 70 km deep), 0 intermediate (70-300 km) and 0 deep (more than 300 km). 0 reached M4 or more. The places USGS named most often were Dana Point, CA (3), Signal Hill, CA (1), Fontana, CA (1).

### What to do in an earthquake

If you feel shaking: **Drop, Cover and Hold On** until it stops. Stay away from windows and heavy furniture, and do not run outside during the shaking. On a coast, strong or long shaking is a natural tsunami warning: move to high ground or inland at once, on foot if you can. Then follow your local officials; this page is not a warning service.

In Los Angeles, Drop, Cover and Hold On. Keep emergency alerts turned on: ShakeAlert warnings reach LA County phones automatically through Wireless Emergency Alerts.

## FAQ

### Was there an earthquake within 100 km of Los Angeles today?

USGS listed no quake of M2.5+ within 100 km of Los Angeles in the past 24 hours (as of 11:27 UTC). Smaller quakes may still appear on USGS ShakeAlert and the MyShake app.

### How many earthquakes does Los Angeles have per year?

From 1996 to 2025, USGS recorded about 19 quakes of M3+, about 2.4 quakes of M4+, about 0.1 quakes of M5+, about 0 quakes of M6+ per year within 100 km of Los Angeles. Counting all sizes, local networks record far more, because most quakes are too small to feel.

### What was the biggest earthquake within 100 km of Los Angeles?

The largest quake in the USGS catalog for this area since 1900 is the M6.7 Northridge, California, earthquake of 17 Jan 1994. The table above lists the largest 8.

### Where can I get official earthquake alerts for Los Angeles?

[USGS ShakeAlert and the MyShake app](https://www.shakealert.org/): early warnings for Los Angeles County through Wireless Emergency Alerts, Android phones and MyShake. [Southern California Seismic Network (Caltech and USGS)](https://scedc.caltech.edu/): the detailed catalog and maps for Southern California, often faster for small local quakes. [City of Los Angeles earthquake information](https://earthquake.lacity.gov/): city information on quakes, retrofits and preparedness.

### How likely is a big earthquake in Los Angeles?

No one can predict it. USGS long-term forecasts (UCERF3) put the chance of a M6.7+ quake in the Los Angeles region within 30 years at about 60%. It is a long-term probability for planning, not a forecast of a date.

### Why do I feel small earthquakes in LA so often?

The LA area has dozens of active faults, and a M3 quake under the basin can be felt across many neighbourhoods because the soft basin sediments amplify shaking. Most of these quakes cause no damage.

### Can earthquakes be predicted?

No. USGS states that no scientist has ever predicted a major earthquake. Scientists can only estimate the long-term probability of quakes in an area. Early-warning systems such as ShakeAlert detect a quake that has already started and warn seconds before the shaking arrives.
