4.1 Earthquake Southern California. Largest EQ in swarm of over 1000 in last 3 years. Monday night.

Ajouté : 2026-06-04

[00:00:02]All right, welcome back here folks to a Monday night, late Monday night here.

[00:00:08]It's 11:23 p.m. California time. First day of June. Hope everyone had a decent day out there. Latest activity here on the earthquake 3D globe shows a 4.7 earthquake here in the red flag, well green flag, excuse me, down here across the uh Peru Chile Trench.

[00:00:26]Hot spot of earthquake activity here recently. still watching this region here potentially for a mega quake because an area u around the Santiago Chile to the north and to the south here where all this activity is stirring up um has not had any sufficient rupture here in about 11 years meaning anything above 7.0 so watching that very closely considering the uptick in earthquake activity there recently uh some large and rare quake activity around the Italy area earlier this evening 6.2 two earthquake. Uh this well underneath the area at 151 miles deep. There's only been about five or six earthquakes here, specifically in this area of 6.0 or greater since records have been kept. So this is definitely what you would consider a rare large magnitude quake for the area. We do have to watch the regions and of course the volcano activity around the Italy area considering this deeper earthquake here.

[00:01:25]Uh, I don't see any um aftershock features at all. None. Zip zero. But again, that's a pretty uh super deep earthquake there at 151 miles. Um, interestingly enough though, following that 6.2, and you know, whether you think it's a just a coincidence or not, there's the 6.2 that struck at 1512.

[00:01:49]This is local time here, California time. It was only a short time later, about 10 minutes later, um 15 minutes later maybe, we had that 4.1 show up there in Southern California. Now, think about this. Can a 6.2 earthquake trigger earthquake activity thousands of miles away on the opposite side of the globe? Potentially.

[00:02:11]When we're watching that 6.2 and two earthquake come in on the seismograph stations. We've seen a an unusual spike show up there on a number of stations around the globe. So I do think you know even though you know if you look at it here Italy compared to California not opposite sides of the globe but still uh well they are opposite sides of the globe but not directly. Uh, I do think that may have u potentially triggered stuff out here. Uh, because Southern California here for the most part was pretty quiet. It was only 15 minutes later from that 6.2 we seen that four-pointer come in. 4.1 earthquake to be exact. It's possible. It could have been just a coincidence here, but uh I don't consider anything coincidence when it comes to plate tectonic movement out here. It's all connected. Definitely all connected. So there's that 4.1 uh was felt uh fairly uh broadly across the area. Not a huge earthquake, but a larger one in the mix of earthquakes there across Southern California recently. Uh this area of the Johannesburg area been swarming like crazy. In fact, we've hadund almost 160 earthquakes here. I believe that 4 Yep.

[00:03:23]4.1 is the largest here in the uh Johannesburg area. that's on the Garlock fault shear zone, which is a major shear boundary here. Runs opposite what you normally see across the west coast here, which is which is a north northwest or north to south movement here uh in terms of the faults. This runs opposite. So, we get a lot of uh a lot of tension building up out here across this area of the of the Southern California region.

[00:03:51]Very dynamic area. You can see it here on the fault map. Um, if we go back the last eight months or so, maybe even longer, this area has just been swarming like crazy. Um, hundreds and hundreds, probably well over a thousand earthquakes or now. We can double check that real quick and see what we got. Just, you know what, just for the heck of it. So, let's go back here in the last Oh, I just want to go back the last three years and we're going to specifically check out, excuse me, that little area around the Garlock fault shear zone. It's looks like it's happening right about here north of California City and it's probably going to show quite a bit of earthquake activity. But I just want to cover a small area to show you guys the intense swarm of 2.5 and above uh that's been occurring there across the area of the Garlock fault shear zone. So it looks like the largest here 4.1 um in that cluster that goes back here a couple years. So interesting. Yeah, we've had the largest event here today with this swarm of earthquakes. Now it's only showing 47 earthquakes, but these are above 2.5 uh magnitude 2.5. We can redefine that and put all magnitudes here. And I think it'd be a a pretty crazy number.

[00:05:16]Let's go like that. minimum magnitude uh zero.

[00:05:21]Let's see. It's probably gonna be a crazy number. Let's see. Yeah, look at that. There's a southward migration with this. See that?

[00:05:30]Started up here north. This is some older activity. It looks like working its way down south here to newer movement. And it's uh I tell you what, it's got some well- definfining feature out here of some migration. Largest magnitude. Go back the last three years. And that is the largest 4.1 1,131 earthquakes uh the smallest magnitude and they actually covered some small magnitudes there interestingly enough. Uh but that's a that's a lot of activity there.

[00:06:01]Southward migration. It's you know it's kind of working its way off of this fault boundary towards the south here.

[00:06:16]nothing large, you know, but this area of the Garlock fault shear zone uh can see some big events. Let's go over here to the Caltech website and um I'll show you guys the um the information on this Garlock fault shear zone.

[00:06:33]Uh most recent surfer surface rupture, look at that, was probably around 1050 AD. That's a long time ago. Long time ago. And that was near to Hatchip.

[00:06:44]um near Johannesburg around 1500 it looks like and that's still you know over 500 years the slip rate runs fairly low at 2 to 11 mm per year averages about 7 mm per year but at you know over 500 years um that is in a great number there probably sufficient stress there to produce a big earthquake interval between major ruptures run around 200 to 3,000 and years. Crazy depending on the fault segment. So probable magnitudes run about 6.8 to 7.6.

[00:07:23]So you know we're definitely within that window of potential there. But who knows? All all I know is that's a a decent swarm of activity out there recently. So we do have to watch that.

[00:07:36]you know, San Andreas faults the primary area that we do have to watch, but there's other fault systems out here lurking that have potential for big earthquake activity. Uh, so far today, that's the only area of interest. In fact, we've seen that 4.1. Couple minutes later, a 2.6 and a 2.7.

[00:07:55]And, uh, total tally today looks to be about 29 earthquakes.

[00:08:00]Further up north, San Francisco has been unusually quiet. You know, it's starting to get a little concerning here because at first it's like, okay, San Francisco's quiet. And then days go by and days go by and there's really hardly anything going on here across San Francisco. Not even any microquake activity.

[00:08:21]So, just a little on the um unusual side. Northern California up here.

[00:08:27]Couple earthquakes um off Northern California coastline. Let's go check out the uh slow slip event map this evening.

[00:08:34]See what we got for the trimmer count.

[00:08:39]Wow. 172. There we go. Back to a big uptick here across the southern end of the Cascadius abduction zone. What that means is the well the Wand Fuka plate here or the southern end of the Wand Fuka which is technically the Gorda plate is being shoved underneath Northern California further. So, you get this the slow vibrational frequency between the two plates as one slides past one another uh into the deeper area underneath Northern California. And that's great and all for um you know relieving strain down into this area underneath this area, but at the same time it's ultimately adding stress across the locked zone. The locked areas where uh we get those big earthquakes.

[00:09:22]So, watch for increasing movement out here across northern California. uh considering the uptick in trimmer counts there. Washington and Oregon pretty quiet. Yellowstone, nothing going on there. Uh some scattered earthquake activity across Texas, Oklahoma, and the New Madrid seismic zone, but really nothing big.

[00:09:43]Uh there's that 4.5 coming into the Chile area.

[00:09:48]It's been a hot spot of activity, but been watching this area in between two major zones here. We got to go back uh go back the last 30 days here. We had a 6.9 up here. More recent six pointer outside of Santiago, Chile. A lot of deep activity underneath this area. Now we're start starting to see this region fill in in between these two zones. See this latest quake? We've had a lot of activity here recently filling in. And this is the area I'm talking about that has not had any 7.0 earthquake or above in 11 years. So, yeah, something uh potentially could be building.

[00:10:28]Um, let me modify my search here. I did have the uh map pulled up that would show 8.0 and above, but it looks like I revised that.

[00:10:40]So, let's go ahead and do that real quick. Uh, I want to show you guys the 8.0 earthquake se sequence. Our last one of course was back in 2025 last year the curl camchchatka trench Russia area that was the last earthquake um in technically four years since two 2021 but we did have three eight pointers back there in 2021. So that potentially could have offset us a little bit in terms of the typical 8.0 earthquake or above each year we should see at least one.

[00:11:15]Uh but I really can't find anything here that goes back uh that extends that far in terms of the the intervals. Let me see here.

[00:11:24]89 to 94. That's about five years. Um but if you look, we had two that year and then it almost became regular there um for an eight-pointer each year. So I am thinking folks, I'm going to go out here on a limb. I'm thinking that we will probably see an eight-pointer this year again.

[00:11:46]Uh we've seen a number of seven pointers. We average between 14 to 16 7p pointers each year out here. But eight pointers should happen on average uh once a year. And considering that we had that gap of four years, we should be back in the regular cycle here. We've seen eight pointers. So those eight pointers we need to watch very closely because I do think the subduction zones here that are showing elevated activity such as the Pu Chile trench need watching closely that could easily see an eight-pointer and also uh the Izu trench up here in the Japan area. This whole area right here is super primed I think for some larger activity.

[00:12:27]The ISU trench here has been seeing quite a bit of deep activity followed up by surface adjustment. And this area has got a huge seismic gap. There's a little gnat that tried to enter into my mouth.

[00:12:39]Hello.

[00:12:42]That was not cool. All right. But there's Yeah, there's a huge It's one of those little squishy gnats.

[00:12:50]It's bugging me. Uh but yeah, watch this area right here. Huge seismic gap.

[00:12:55]There's really been nothing here of historical activity in terms of larger movement. You literally have to go over here to the oceanic crust map to see this major subduction zone. And that's where you can get some big earthquakes.

[00:13:06]So, I do think we'll see uh quite a few more sevenpointers and um probably an eight pointer or higher out here this year. We're halfway through the year just about. Um so, that could easily uh happen here.

[00:13:21]Deep activity across Italy. No signs of any adjustment around the area yet. Um, New Zealand, there's a 3.1 underneath North Island, Alaska area. There's a handful of earthquakes up there, but really nothing big.

[00:13:37]But look at the pretty chilly trenches just lighting up like crazy.

[00:13:42]There's another 2.9 coming in here that could very well pop off a big one.

[00:13:47]Atlantic Ocean. Uh, some newer activity up here in the northern Mid-Atlantic ridge. Uh, that's a 4.6 six that is showing up here on the USGS map earlier this evening as well. Iceland seen a little bit of activity.

[00:14:03]Uh aside from that, uh let's see what we got here for some space weather activity. A little bit of seaflare activity. Actually, it looks like we made it into the mflare category.

[00:14:13]Barely. Just a very impulsive mflare.

[00:14:18]Let's see where that's coming off of here.

[00:14:21]Well, Kevin hasn't covered that.

[00:14:23]surprised not a big inflare threat. It didn't even show up here on the um the noteworthy flare threat map. Uh but I'm thinking here maybe off of this area. Let's go check out the uh movie here real quick. 48 hour movie and we'll see what we got.

[00:14:43]Put this up here uh real quick and we'll zoom this probably about to right here and see what we got here.

[00:14:53]Let's watch this sun here and see where that inflare peaked out from.

[00:15:00]Oh, I I didn't really see it.

[00:15:14]I didn't see it. I don't know if anyone else seen it or not, but um that's a little odd.

[00:15:25]Potentially maybe one of these far side sunspots here that are coming around.

[00:15:29]There's a couple different areas here in the southern uh eastern area of the sun that looks actually fairly complex. Also got another giant region back over here coming around the bend. So we do have some active areas that I think will increase the the u flaring activity here uh coming up in the next couple days.

[00:15:50]The ones that are currently facing this though look fairly uh stable.

[00:15:54]So for now the flare threat will remain at a 5% chance here for xflare inflair at 25 clair at 90% chance. No major roars in uh roars in the forecast for now.

[00:16:09]Storm prediction center. Let's see what we got here for the uh Tuesday outlook across the northern plains. It looks like the Dakotas there. They actually added a 5% chance there for some tornado activity. Green here is the 2% but uh there's some potential for some spinning water vapor out there tomorrow. a little bit of wind and some very large hail across that dashed area. So, just a heads up, we're going to be out here in the upper 90s all week. That's not the feels like temperature. That is the actual air temperature. And unfortunately, we are surrounded here where I live uh by a lot of orchards and also rice fields. So, as the sun is beating down on that water, it cooks, right? It puts more moisture into the air and it literally feels if you got a 98 degree temperature out here. It can go up to around 105 110 feels like temperature easily uh just because of the water. A lot of rice fields out here. But anyway folks um just be on guard. Uh large earthquake activity is a part of life and it will continue. It's not going to stop. We live on a very active planet. The thing is to be prepared. keep an eye on areas of interest and right now I'm watching the the princely trench very closely and also up around the Japan area but anywhere else out here can have a large event we could see New Zealand Southern California is prime for an 8.1 the Cascadia you know but areas of interest right now things that are really picking up uh these two areas mentioned have a good night folks seismograph stations out there look pretty quiet for now we'll see you guys out here for the Tuesday morning update have a good night get some Sleep.
