"Just coincidence vs offshore quake." Uh huh lol. Like some random slots or something.
Seen same pattern plenty of times on either side of the plate.
Take those over that 1.7 NYC any day, atop a high rise at 545 a.m. with no earthquake experience.
First responders flooding area, popping manholes.

classic strike slip...Just about right on the San Andreas fault (the fault has a slant here as it bends). Initially plotted as a 4.4, and readjusted to 4.2 (4.15mw)
Did not feel this one, although I was up at that time last night. It appears the energy went mostly west and southwest of the fault.
This area of the fault is over due and worthy of keeping an eye on for a 4+ quake.
Interestingly, we just drove through the Cajon pass (hwy 215) on our way home from a holiday trip out of state. Major pass through the San Gabriel mountains there.
Single quake..no aftershocks. (still stuck..but a quiver).

Just got done cleaning up after this one; lost a hanging lamp in the kitchen and had items fall off shelves. A very sharp jolt and shaking up here in Lytle Creek. Water level in creekbed has risen over the past day so wondered if a quake would follow. Wondering whether this is a foreshock of a largter quake as there have been no aftershocks at all during this past first hour. Very odd.

also.."lack of aftershocks".
Aftershocks are the readjusting of a plate to a new position. Not all 4 mag quakes create them, but there's usually a few, at least microquakes.
quiet..
If that continues (and it hasn't been that long since the quake), I would take it as meaning that it slipped..then relocked.
Prior to the Loma Prieta quake, there was a 5pointer near Lexington reservoir. It was followed by a "shudder" of microquakes in an area that had been locked for decades. Then...dead silent seismically.
The USGS put out a rare warning for 2 weeks it could be a precursor.
After two weeks, everyone laughed and hung their pictures back up (well, I didn't)
2 months later the Loma Prieta quake hit.
now, I don't see a "shudder" after this one, or aftershocks either. Just nothing. This area of the fault has done that before with nothing big coming after.
Faults are a little like people..each have their own character and personality. They don't all act the same way (or segments of the same fault aren't consistent in behavior).
For instance, hundred miles north is Parkfield. It's underlain by a lot of talc along the fault, slips more frenquently ...even on a schedule. Same fault, different way of moving or "chattering".
Wrightwood segment connecting big bend through Tejon with Big bear bend to the south. Another "different" character. Different rock, different stress, different limits and chatters "differently"
Humans have spent eons trying to understand what it's saying..all in different languages.
But it's worth watching, for sure.

That water increase is worrying.
Back in 1989, Opal creek in the santa cruz mountains started rising and overflowing it's banks 45 min prior to Loma Prieta (no rain, in a drought year).
There was also the smell of sulfer near some of the canyons that intersect the faults up to 3 mo prior to the quake. The smell intensified off the scale just after the quake, and slowly dissapated with time.
I was in the Santa Cruz mountains during the 1989 quake, and also studying geology.. and I remember these odd things that made total sense in retrospect.
Not all faults give the same precursors (or even from quake to quake), but it's good to keep an eye out for things like that.
I'm just north of you..and these things concern me as well.
I'm sorry you had so much damage. You must have been very close to the epicenter. Might want to make sure everything is bolted down.
I knew enough geology back in 1989 to remove heavy photos from the walls and make sure appliances, bookshelves and large tvs were secured.
Forgot about my microwave..and when I got home after the quake, found it on the other side of the kitchen (at least 6 feet from it's normal shelf).
Good reminder to have an emergency kit.
All precautionary, of course. There's no sure fire way to tell if that segment is finally going to go tomorrow..or take another 30 yrs.
But yeah, the water levels would get my attention. Then again, we did have rain this week.
Stay safe, Ellen

And we did have rain but only 1/2 inch. I’ve been watching our small spring fed creek for years and a rose usually means activity on the San Andreas and a drop, the San Jacinto. I got to discuss it with Lucy Jones and Egoll Hauksson a few years back and they mentioned that well water levels are also affected but there was no active monitoring at that time.

some of that is routine and precautionary, but they're obviously noticing much of what has been discussed here, as well.
It's also good to understand while it may increase chances of a larger quake, the chances of a major quake are still less than not having a major quake (to keep in perspective).

could be a forshock, as in the 1970s there was a 4.0 forshock to the 5.2
occurred in SoCal is near Lytle Creek in Cajon Pass, where the San Andreas and San Jacinto faults come together. In 1970, there was a M5.2 with a M4.0 foreshock in close to the same location
Though ultimately a forgettable event, and certainly overshadowed by the San Fernando (Sylmar) Earthquake which followed five months later, the Lytle Creek quake did get the attention of much of southern California -- it was felt strongly as far away as Barstow, Mojave, Oxnard, and Palm Springs, and even caused tall buildings to sway in downtown San Diego.

The Associated Press The Associated Press A magnitude 4.2 earthquake shakes a wide area of Southern California. No injuries are reported Story by By JOHN ANTCZAK and STEFANIE DAZIO, Associated Press • 3h
LOS ANGELES (AP) — A light but widely felt earthquake shook Southern California on Friday. There were no immediate reports of damage to buildings, other infrastructure or injuries.
The U.S. Geological Survey said the 10:55 a.m. quake, after several revisions, was a magnitude 4.2 and was centered about a mile (1 kilometer) northwest of Lytle Creek, in the San Gabriel Mountains about 45 miles (70 kilometers) east of downtown Los Angeles. The depth was put at 5.5 miles (8.8 kilometers).
A quake of such magnitude is typically not strong enough to cause significant damage.
Michael Guardado, who works at the front desk of the San Bernardino National Forest's Lytle Creek Ranger Station, said the “building shook hard.” Officials were working to determine the earthquake’s impact on the area, and Guardado said he had heard that “a lot of rocks” had fallen onto Lytle Creek Road.
Cari Torguson, a bartender at Melody’s Place in Lytle Creek, said she felt “a hard boom and a shake.”
“It wasn’t very long, but it was scary,” she told The Associated Press.
A decorative glass mushroom above the bar fell and broke, and a jar of instant coffee toppled off a shelf in the adjoining store, she said. Only a handful of people inside the building, and no one had time to duck under a table.
The quake was centered within miles of the home of minor league baseball's Rancho Cucamonga Quakes. “What's in a name, you say,” the team quipped on social media.
The tremor was felt as a slight rocking in downtown Los Angeles. Shaking was also reported in several surrounding counties and cities including Long Beach, more than 50 miles (80 kilometers) southwest of Lytle Creek.
The Los Angeles Fire Department said there were no immediate reports of injuries or damage to buildings and other infrastructure within the city.
To the east, San Bernardino County fire authorities also said there were no damage reports or calls for service related to the quake.
The quake occurred in Cajon Pass, where the San Andreas and San Jacinto faults come together, veteran seismologist Lucy Jones said in a social media post. In 1970 there was a magnitude 5.2 quake with a 4.0 foreshock close to the same location, she said.
The earthquake warning system called ShakeAlert initially estimated the magnitude above 4.5, so alerts were sent to cellphones, the USGS said in a social media post.
The system is designed to detect a quake and almost instantly send alerts to areas where significant shaking is expected to arrive, giving people time to protect themselves or slow down trains and buses.

Magnitude 4.2 earthquake jolts Southern California Story by Nathan Solis, Rong-Gong Lin II, Priscella Vega • 3h Los Angeles Times
A magnitude 4.2 earthquake rattled Southern California on Friday morning, less than a week after a magnitude 4.1 New Year's temblor that shook attendees at the Rose Parade in Pasadena.
The earthquake, which struck at 10:55 a.m., brought light shaking to swaths of Southern California, as defined by the Modified Mercalli Intensity Scale, according to the U.S. Geological Survey. That’s enough shaking to rattle dishes and can feel like a vehicle striking a building.
The epicenter was about 1 mile northwest of the remote community of Lytle Creek in the San Gabriel Mountains of San Bernardino County, 12 miles northeast of Rancho Cucamonga, 27 miles northwest of San Bernardino and 45 miles northeast of downtown Los Angeles. Residents in Fontana reported heavy shaking strong enough to set off car alarms. In Rowland Heights, people said they felt they were being rocked back and forth and the doors and beds shook.
The epicenter was near Lytle Creek in the Cajon Pass, seismologist Lucy Jones wrote on social media. Jones noted this is where "the San Andreas and San Jacinto faults come together. In 1970, there was a M5.2 with a M4.0 foreshock in close to the same location."
David Loyola was about to bite into his chicken bake at the Rancho Cucamonga Costco when the rumbling interrupted his lunch. He stared at his co-worker sitting across from him.
"What the hell," Loyola said, as he felt his body jump up and down, akin to driving over a speed bump. The two FedEx employees looked at each other, then at their surroundings to make sure they "weren't acting crazy." Nothing appeared to be broken or toppled over by the earthquake but "people just looked astounded," he said.
Minutes later, his wife called to check in on him. "Yeah, I'm good," Loyola told her. "It just interrupted my lunch."
Weak to light shaking was felt throughout Los Angeles, Orange, Riverside, San Bernardino and Ventura counties, as well as in northern San Diego County and parts of the Mojave Desert. The earthquake occurred just west of the Cajon Pass, through which Interstate 15 runs, the main route between Southern California and Las Vegas.
The California Department of Forestry and Fire Protection said there were no reports of damage or calls for service related to Friday's earthquake. The Los Angeles Fire Department also reported no injuries or structure damage.
Los Angeles Mayor Karen Bass reminded Angelenos about being ready for the next earthquake.
"An earthquake just shook the L.A. area this morning," Bass wrote on social media. "This is a reminder that earthquakes can happen at any time. Make a plan to prepare for emergencies at ReadyLA.org."
An average of 25 earthquakes with magnitudes between 4.0 and 5.0 occur per year in California and Nevada, according to a recent three-year data sample.
The earthquake occurred at a depth of 5.6 miles. Did you feel this earthquake? Consider reporting what you felt to the USGS.
