5.7 Earthquake Nankai Trough Subduction Zone. Deep Eqs Japan Region. Saturday update.

Added: 2026-05-09

[00:00:01]Hey, how's it going out there folks?

[00:00:03]Welcome back here to a weekend. It is Saturday, this afternoon here along the West Coast, May 2nd, 2026.

[00:00:12]Latest activity here on the earthquake 3D globe. Let's see what we got here today. 3.3 across the uh looks like the middle America trench there, southern end, also a 1.0 across California. See what we got going on here across the area this morning or this afternoon. 2.5 actually coming in near Filmore, California. That's north of Los Angeles, right around a couple different faults there.

[00:00:36]Um it's been a little bit since we've seen activity here in this zone. There's been a couple smaller microquakes out here in the uh last week or so, but just a little bit of movement happening out there in Southern California right now.

[00:00:50]It's been Yeah, it's been kind of quiet.

[00:00:53]I know we've had a couple three-pointers around the San Andreas fault that come and go. Uh here's the last week of earthquakes above 2.5. Notice that cluster uh kind of working its way here on the Pacific side of the plate boundary. Also some on the North American side of the plate boundary.

[00:01:09]That's the San Andreas fault here.

[00:01:11]Holding steady. It's holding steady. Uh been a while since we've had any large earthquake activity out there.

[00:01:18]Uh let's see what else we got here across the uh state of California. A little earthquake on the creeping section. That is indeed the creeping section here where we get uh well tectonic slip for the most part instead of locking up like other sections of the San Andreas fault. Uh this just kind of creeps along with microquake and sometimes some twos and threes out there. It's got a little activity on it today. Uh nothing big, but that is uh you know that's above 2.5 2.6 there.

[00:01:47]Bay Area, pretty quiet. Northern California, there's that earthquake from last night. Deep into the Cascadia, 24 miles deep for that quake. Pacific Northwest, relatively quiet.

[00:01:58]Uh Nevada, see what's going on here in Nevada. Couple earthquakes this morning.

[00:02:03]Uh in the one range also 3.5. I do appreciate the comments coming in there uh from the locals out around Silver Springs and Fallon, Nevada, and other areas in the vicinity of this earthquake activity. I appreciate your comments coming in. let me know you felt some quake activity. I always like to compare that to the data that's coming in here from the USGS in regards to whether it's accurate or not far as if they're reporting all the earthquakes. Kind of hard to say, you know, if if they are or not, but keep those coming in if you're out there feeling those quakes. Uh and as you can see today here in the last 24 hours, we got uh the largest going to be this 3.5 early this morning about 7:00 or so. Uh the area down south outside of Las Vegas just went completely quiet after producing a 4.4 and a number of other earthquakes. I do want to watch this area closely because of the elevated seismic events going on around the area, you know, across the entire state of Nevada. In fact, uh do think these uh older faults out here are starting to wake up. We'll continue to check back on that though. It's just odd how it just went super quiet like that. Yellowstone National Park, nothing showing up there.

[00:03:12]But let's go. uh check things out. See what's going on here.

[00:03:20]And we'll check out this seismograph station. See if there's anything kicking up. There's a that was last night just after 7 o'lock.

[00:03:29]Let me see here.

[00:03:32]Did that show up on anywhere else? It didn't.

[00:03:39]So, to me, that looks like some type of outside interference that popped up on that graph. So, I like I say, I don't see too much uh it'd help if a lot of these were working, but they're not. Just it's a hit and miss with the seismograph stations out here.

[00:03:55]A lot of these are offline there across Yellowstone.

[00:03:59]Uh but that blip that we had seen looks like it was outside interference. There is some small earthquake activity along the eastern side here of Yellowstone, but nothing big. Uh and they won't get to those until Monday morning, trust me.

[00:04:14]Oil fields, Texas. Yeah, same thing. Day in day out. Let's take a look here at the uh total tally of earthquakes around the Peran Basin and areas outside of San Antonio. Look at that. Quite a bit of earthquake activity. In fact, 1,139 is the total count out there in the last 30 days. Quite a bit. Occasionally, we get some we can get some five pointers out there in the uh the mix of oil fields and uh uh wastewater injection processes out there. Um been a little been a minute since we've had a five-pointer out there, but they can pop up some from time to time.

[00:04:54]Hawaii. Uh, I don't see anything major going on. Still got a little cluster underneath the Paja area. We'll go examine the um Kilawea inflation chart here. See what we have going on.

[00:05:09]See if anything is new out here.

[00:05:15]Yeah, still still going up there it looks like. So, episode 46 will be here in a in a few days.

[00:05:23]Little short window here. Notice how these are just kind of getting shorter and shorter. That's an interesting feature. I do think things are about to change there, but we'll continue to check back on that there as we uh get further in time uh overnight. Let's see what we got up here around Japan.

[00:05:42]Yeah, there's 4.6U Trench. That was early this morning, but that's deep. 246 miles deep. And then a 5.7 here. Relatively shallow. That's A B C D. That's along section D. It looks like of the Nankai trough. A B C D E over here. This is a major subduction zone with five segments that uh historically have ruptured in pairs uh and occasionally all at once uh as well. But these pairs of earthquakes that happen from time to time are uh they can happen within a day of each other or a couple years of each other. Uh and then when we don't get a when we don't get a section here that uh you know fails to participate in that rupture s such as section E which did not rupture back in the 40s there when the last ABC and D ruptured. Uh E did not participate. So that means the next goound here will probably be a full rupture. We've already looked at this a handful of times there in the last several months. So, just watch it.

[00:06:50]That's kind of a larger event out there.

[00:06:52]5.7.

[00:06:55]Let me see if there's any aftershock activity stirring up.

[00:07:00]Go over here to the Japan Meteorological Agency here. See what we got. Um, so they're reporting that right here.

[00:07:11]5.7 Uh I don't see too much aftershock activity there.

[00:07:22]This is all just bunch of different uh earthquakes on the map. And I'm just kind of getting the location here. Right there in the X is where that uh earthquake struck.

[00:07:36]Yeah, that's not a good spot here because that deeper activity I said last night this deeper activity is going to strain this region. And sure enough, there's there's one from yesterday that was 223 miles deep. And then we had another one early this morning at 1:00 for 4.6.

[00:07:57]That 5.7 struck an hour later. So this area is quite strained.

[00:08:02]Really strained. Um, let me show you guys here.

[00:08:08]See if I got my Nankai Nan uh Nankai trough. Normally, normally I have an image here uh to show you guys, but we can just go to the Wikipedia article here real quick. Show you guys this map. See if they still have it.

[00:08:30]Well, Looks like they're getting rid of a lot of the images there.

[00:08:40]I was looking for the segments of the Nankai trough. Kind of give you guys a Oh, there it is. Here's just a simple layout A, B, C, D, and E of the Nankai trough.

[00:08:56]in that earthquake this morning, that 5.7 looks like it did strike here around section D, maybe maybe over towards C.

[00:09:04]But that's not a good sign there when we get that large of a magnitude.

[00:09:08]These uh earthquakes, they do um kick up here.

[00:09:15]They have earthquakes, mega quakes, not just small quakes, but mega quakes that uh can really produce a tsunami out there.

[00:09:29]The most recent large-scale earthquake to occur in the Nanghai trough was back in 1944 um and 42 if I remember right. There's 42 and 44. Uh but that those sections there did not take E with it. Section E.

[00:09:42]So anyway, we'll cover this a little bit later on pending nothing else uh bigger happens in between now and then. Uh but that is definitely a concerning earthquake right there. Deeper activity further stressing the Nankai trough.

[00:09:58]All right. Uh let's see. Typical movement there across the Philippines into the Indonesia area. They got uh a little activity across New Zealand it looks like as well. Right on the plate boundary 4.0 uh today. At least are today. They're already in the future. I believe it's already um Sunday over there. I think uh let's see anything major going on across the uh man. Nothing major going on across Central America. Just some looks like a four-pointer out there.

[00:10:30]South America, same as last night. A slight increase there along the Pchili trench that follows the activity down here into the South Sandwich Trench. It looks like there was maybe another earthquake down there. Where we at this event? Yeah, it was uh 3:31 in the morning for a five-pointer. That's a second earthquake down there in the last couple days. Last 30 days of activity.

[00:10:55]I'd watch this area up north here. It's a major subduction zone. And this area uh the subduction zone kind of works like like clockwork, if you will. When one section of the uh subduction zone fills in, it almost guarantees that that will follow it some days later. So, I'm thinking this northern end here uh should see some activity. These are relatively deep earthquakes up here.

[00:11:18]Well, one of them is, but anyway, we'll keep an eye on that.

[00:11:25]Uh the Atlantic Ocean fairly quiet still building up magma underneath the Savi area of Iceland. We'll cover that more as we get closer to an eruption, which could come. It never no telling here pretty soon. It's been building up quite a bit of magma underneath the area. Uh Mediterranean areas got some twos and threes out there. Nothing big going on for now.

[00:11:50]Uh but we will watch the Japan area.

[00:11:57]All right, let's see uh see if we got anything on space weather. I know that volcano over there in the Philippines uh I think it produced um uh an eruption there. I think it's been within the last 12 hours. It's a volcano southeast of Manila in the Philippines, but that seems like it's has an eruption every couple years or so. Been an ongoing thing with that volcano.

[00:12:27]Uh, but we got quite a few volcanoes out there that are uh in eruption stage.

[00:12:33]I mean, we can double check that real quick. Let me see.

[00:12:39]Uh, I normally use the um I thought I had this bookmarked Volcano Discovery, but I guess I don't. I don't know what happened to it. Uh this site here normally uh shows quite a bit of uh volcano activity and whatnot. This was published 16 minutes ago eruption there across the Philippines.

[00:13:14]Uh I believe you say Mayon Mayon volcano. I believe that's how you pronounce it right here. Ash advisory issued. Quite a few volcanoes out there.

[00:13:24]I mean, it's the typical ones that are, you know, they're almost always erupting, almost always erupting or going through little pauses and then eruption again here in a few months. Uh, but nothing out of the norm. That's just typical.

[00:13:40]All right, space weather activity here.

[00:13:42]Little seafare movement in the last few hours, it looks like. Let's see where that's coming from.

[00:13:49]It could be a combination of all of them. I notice a couple areas back over here around the eastern limb as well that's uh brightening up a little bit. Let's see what we got today for the magnetogram image.

[00:14:03]Man, these are just kind of fading off.

[00:14:10]I'm really not impressed with any of these right now. Let's see what we got on the eastern limb. Couple different areas coming around, but it's hard to tell in terms of the complexity of those sunspots. So we'll have to wait for them to get into more earth directed view here in the coming days. Right now flare threat dropping as expected. 5% chance there for Xflare. Mflare at 45% chance.

[00:14:31]Cflare up around 99% chancer. So I just I don't really see anything of major value out there in terms that it will produce a strong flare. It's just they are kind of uh dissipating.

[00:14:43]100% illuminated moon this evening. If you got a chance, go check that out.

[00:14:48]Beautiful, I'm sure.

[00:14:51]Uh, no major roars there in the forecast for now. Let's check out the asteroid department. See if anything's on the menu for that.

[00:15:03]I got to get my yard cut out here. The field cut. Got a little bit of rain coming in Monday. So, I want to try and get that done today. I'll be out here out on the uh side just kind of getting this mode.

[00:15:16]Uh nothing really nothing in terms of close proximity. Here's the distance. Millions of miles for the majority of them. And that's fairly safe as well. Uh so no doom and gloom. As we get closer to 2029 here, we'll start talking more about Apous and the uh close encounters that that poses here to the planet. Uh we got a couple years though.

[00:15:46]Storm Prediction Center. Looks like a little area out here across Florida. Um little tornado threat. They included a 5% chance there around Orlando. Little bit of wind threat. Yeah, maybe a little bit of hail threat out there as well, but nothing big. No major severe weather outbreak for now. Uh there's our storm system across the West Coast. It looks like uh getting some rain. That'll stir up some some storms around the southern plains, I'm sure, as we head a little bit deeper into next week. Right there.

[00:16:21]And then after that, uh well, I guess we'll have to see what happens here.

[00:16:26]It's interesting how we got moisture just popping up here over the West Coast and then it forms into a low pressure and then takes off to the east. Just odd how that's kicking up like that.

[00:16:41]Let's see what we got here for any uh major ridging or low pressure troughs out here. We're going to go back a little bit to uh May 2nd.

[00:16:56]Yeah, we got this high pressure parked right over the West Coast. I know Portland and Washington going to cook uh for this time of year. It's rather warm up there for them. that's going to intensify here it looks like uh as we enter into May.

[00:17:11]Then after that hopefully that thing breaks down. That's not a good spot for the high pressure. I mean if you like dry, stable, hot weather, so be it.

[00:17:20]That's going to be your your cup of tea right there. But that's not my cup of tea. I like a I like a mixed bag of weather in my in my forecast, you know, not just dry consistent heat.

[00:17:33]Bring on the rain. Bring on the wind.

[00:17:35]Bring on May showers. I think I need to live somewhere where that happens every year.

[00:17:42]I mean, we've been pretty decent here with the rainfall out here in California. Uh, April was a fairly wet month for us, but March, not so much.

[00:17:50]So, where I don't know where we're at in the rainfall bucket, but close to normal, I would say, in terms of the averages out here across California.

[00:18:02]All right. Uh let's see here. I think that's about it.

[00:18:07]Keep an eye on that region there, folks.

[00:18:09]It's it's uh it's definitely increasing increasing.

[00:18:17]Now, we'll probably cover more about that Nankai trough a little bit later on this evening. I got to find out where all my images went to.

[00:18:26]I thought I had it up here, but maybe not. I always try to keep a a number of different images up here so I can not go that way. I don't have to go look for them, you know, they're already available to show you guys, but uh something happened. I don't know.

[00:18:41]Alrighty, we'll see you guys out here for the uh Saturday night update. I'm going to go get some mowing out here in the field. So, have a good one. We'll see you guys later.
