Over the past three weeks, more than 1,000 small earthquakes have hit Southern California — mostly in Riverside and San Bernardino counties.
Some are calling the region’s increased seismic activity “swarmageddon,” but seismologist Lucy Jones told the Los Angeles Times that the small quakes don’t mean the big one is more or less likely. According to Jones, there’s only a 5% chance that any single quake will be followed by a larger one.

If the Big One comes, I want the Rats and Weasels to be right at the epicenter.
LOL!
I heard one years ago that was just the opposite - that the oil in the ground "lubricates" the earth's plates, allowing for smooth, earthquake-free continental drift. If we pump all the oil out, the plates will "seize up", pressure will build and we'll all die from the monster quake...
It ain’t no earthquake. It’s people slipping and falling on all the poop on the streets causing the vibrations.
All that can be reliably taken from the increase of small quake number is that there is an increase in movement. The rack that tar is running into the streets probably isn’t a good sign either.
More like they are hitting the Inland Empire rather than SoCal. No one in my part of OC has said a word about any earthquakes. Knock on wood.
CA should ban methane.
Traditionally, this has made it difficult to diagnosis animals which have come down with Parkinson's.
May our dogs stay close to home.

Review of this swarm indicates they are along the projection of a NE-SW trending fault extension. These are not related directly to the san andreas except that they are conjugate faults to the san andreas. YEs, there will be a big one - but not due to this swarm. It only shows stress continues to build.
At least six large ruptures of the San Jacinto Fault Zone are known to have followed the 1857 Fort Tejon earthquake that ruptured the central segment of the San Andreas Fault. These events began with the 1899 San Jacinto earthquake and occurred at intermittent intervals culminating with the 1987 Superstition Hills and Elmore Ranch events. The 1857 rupture spanned a total of 360 kilometers (220 mi) and terminated on the southeast end near the point where the San Jacinto Fault Zone branches away from the San Andreas Fault Zone at the Cajon Pass. In a paper published in the journal Science, Christopher Sanders plotted the earthquakes of the SJFZ by time and location and found that a uniform pattern became apparent. Moving southeastward from the Cajon Pass, the large SJFZ events appear on a line with a slope of 1.7 km per year and Sanders hypothesized that the 1857 earthquake introduced a strain pulse that migrated southeast and triggered large earthquakes as it traversed the SJFZ at that rate.[10

Yep, and Ft Tejon was a biggie (7.9). not a 2.0 like this little swarm. That is nearly 800,000 times larger than this swarm. It will affect other near by faults.
6.4 hit this morning about 8 mi East of China Lake NWS.
Multiple 4.0+ since then.
We felt it yesterday afternoon, lateral slow motion waves in Coachella Valley, though not shown on USGS. Lots of -0.2 Mg quakes, haven’t seen those posted before.
