ATS Thread - Scientists Say Cascadia Mega Thrust Fault Line Deeper Than Previously Thought

reply to post by UtahRosebud


Thanks! Great minds must think alike, because I just opened this thread up to cross-post from my Washington State thread!

I hate to be redundant, but I want to make sure I get this info on both of my threads because it is obviously relevant to both. SO...here it is. Some interesting stuff!

***********
A BIG thanks to my friend AnnMarie who posted the following quoted article on the Quakewatch 2011 thread

This is a newly released article discussing the Cascade Subduction Zone:

Scientists Study Future Megathrust Earthquake In Pacific Northwest

In essence, they are providing further studies to confirm the location of the subduction zone. That it is actually under the peninsula vs off the coast. Right about where the 3.7 quake occured a few days ago....and where it is clearly mapped by the deep tremors.

Please see the linked article, as it has a bunch of good info, but I am going to do some quotes and comparisons:

The section runs north-south from Victoria on Vancouver Island to southern Washington state. Scientists call it a transient slip zone because the fault between two plates slips gradually every 14 months or so. This gradual slip takes place over a two-week period and triggers tremors that are so small people don’t notice them.

Here is a map I have posted more than once that I have stated is what I believe to be a clear indicator of exactly where the subduction zone is...note how it cuts off in Northern California? One of the reasons I think it extends MUCH further than is said:

In this study the slowly slipping section of the fault beneath Washington state was found to be 27 to 42 kilometres deep instead of 25 to 35. Using sound from compressed air sources in the ocean and small nearby earthquakes, Calvert and his colleagues determined how long it took seismic waves to propagate through the Earth. This told them there is a lot of sedimentary rock in the fault beneath Washington state.

42 Km they say??? Hmmm......

I started a thread a few days ago regarding a recent 3.7 quake on the peninsula at 42 km depth. From the OP:

So we have a 3.7 quake (moderate size) right where the subduction zone is and at that depth, it's a bit more concerning. Add to it the micro quakes occuring nearby at a more shallow depth, may (and I stress may) indicate the stress and dynamics going on bellow. I am NOT a geologist. I am just an avid quake watcher. I have watched my area for nearly 15 years now so I know what is unusual. ....

MAP 3.7 2011/07/24 12:19:28 47.708 -123.178 42.3 20 km ( 12 mi) WNW of Brinnon, WA

Experts say a future megathrust earthquake, measuring 9.0 on the Richter scale, will occur somewhere off the coasts of B.C., Washington state and California. That is where the Juan de Fuca and North America plates are locked and are known to slip every 500 to 600 years. The last such earthquake was in 1700.

I have been stressing for awhile now that I think the whole thing could go...but that the area of main concern is California. I still believe that.

Perhaps it is selfishness on my part? I mean, I have always known that I am close to the subduction zone...and the distance keeps getting smaller with each new study. I have to admit that it wasn't until just yesterday that it really hit home how bad it could be personally. I have an earthquake ap on my phone which incorporates GPS. Yesterday, I took a look at the 3.7 quake info (I had been on my comp...no need to use the phone) and I saw the distance to the quake listed. 69 miles. Only 69 miles!!! IF that had been the 'big one'.....my house would have most likely been destroyed and I don't even want to think about everything else. We have dams upstream, volcanos upstream, an ocean to the west. When you look at it in stark terms....I just really hope it never happens.

I honestly hope all the time I have spent on this stuff has been a complete waste and I never really need the info.

WC... have you ever considered submitting a link to this thread to some of the authors or "scientists" who write these articles?

I would think the worst that could happen is they would laugh at you and tell you that you are crazy. Which we all know that you are NOT! However, as human beings, sometimes we are so far inside our own thoughts and training, that thinking outside the box can be a challenge. Scientists are human, therefore they are no different.

You also would never have to worry about your theory being "stolen". Thanks to ATS and date stamps!

Just a thought.

reply to post by UtahRosebud


I have exchanged some emails with a few different geologists from USGS and PNSN regarding some questions I had, but never put my theory out there. The couple of times I hinted at it....I didn't hear back from them.

It never hurts though. Quite often you can find ways to contact them...maybe it isn't a bad idea!

Well, THIS makes for an interesting map! I'll be keeping an eye on that. Oregon has been quite unsettled this week. I think this is in direct relation to the cluster of deep tremors isolated to the South end of the Olympic Peninsula.

Here is only part of the list taken from the above linked map:

Check out the depth on some of those. Especially the ones out towards the coast and the 4.5.

hmmm....and before anyone says anything: NO, it is not considered normal for Oregon to have this many in so short a period. Certainly not unheard of and not worth getting excited over, but not normal.

That is a lot of quakes for Oregon and Washington. The depths are interesting, and so are the locations.

The Scotts Mills area in Oregon looks like there are a few small quakes in the same place and at the same depth, as the 4.5 earthquake that happened in March 1993. That probably does not mean anything, but is kind of close to my area, so I noticed that. Usually this area is kind of quiet, no earthquakes except the ones close to Mt. Hood, so I agree, this is not normal for Oregon.

Looking at this map by depth, it looks like there is a line running down from Washington to California.
Link

It does not usually look like that, but it could just look line a line to me, as it seems similar to the deep tremor map I saw earlier this week. It is always good to stay informed, so thanks for the update.

reply to post by PacificBlue


I definately agree with you. I love the depth map. I use that a lot because I think that it does give you a more complete picture of what's going on.

So I just spent a bunch of time investigating exactly where these quakes are. I am a bit surprised. I should have looked sooner. There have actually been 12 quakes in the same location in the past three days, more than they have had there in five years. Guess where?

Crater Lake. Yup. The USGS lists them as 10 miles NE of Butte Falls...which is actually about 10 miles SW of Crater Lake. Well. This makes things that much more interesting. Here is some info:

source from PNSN

A well-known crater lake, which bears the same name as the geological feature, is Crater Lake in Oregon, USA. It is located in the caldera of Mount Mazama, hence the name "Crater Lake" is something of a misnomer. It is the deepest lake in the United States with a depth of 594 m (1,949 ft). Crater Lake is fed solely by falling rain and snow, with no inflow or outflow at the surface, and hence is one of the clearest lakes in the world.[1]

Wiki source

Mount Mazama and Crater Lake caldera lie at the intersection of the Cascade chain of volcanoes with the Klamath graben, a north-northwest trending basin bounded by faults whose displacement is mainly vertical. At this latitude, the western margin of the Basin and Range province, characterized by north-south to northwest-southeast trending faults, impinges upon the Cascades. Focusing of volcanism at Crater Lake and the development of the shallow magma chamber which fed the climactic eruption are linked to this regional tectonic situation.

North and south of Crater Lake are many shield volcanoes of modest size and many more cinder cones with associated lava flow fields. Both represent short-lived activity at isolated vents. These monogenetic volcanoes are manifestations of regional volcanism throughout the Oregon Cascades.

Remarks: Largest known eruption from Cascade Range volcano. Catastrophic, caldera-forming eruption 7,000 years ago; post-caldera lava and domes 2 ... From a probable altitude of roughly 12,000 feet, the top of former Mount Mazama was lost to eruption and collapse that left the present huge crater and the deepest lake (1,932 feet) in North America. Explosive eruptions built Wizard Island and two other cones (submerged) on present crater floor 3.

USGS source


So I really want to point out that the last known eruption was 7,000 years ago and listed as catastrophic and most important is that there are several modest sized shield volcanos and cinder cones to the North and South of it which is where these quakes are coming from.

I had been seeing the quakes in Butte Falls, but I did not know where that was, or that it was so close to Mount Mazama. Enjoyed reading the information about Crater Lake and the surrounding areas. It seems that area was very active in the past, and that does look like a cluster of quakes.

It looks like it has quieted down, at least for now, but it will be something to watch for in the future.

Oh boy WestCoast... oh boy oh boy oh boy!!!

NEWPORT, OR (KPTV) - Oregon State University scientists say they've discovered an eruption of an undersea volcano about 250 miles off the Oregon Coast.

The April 6 eruption produced a lava flow at least 1.2 miles wide, scientists say, and there were hundreds of tiny earthquakes during the eruption.

The volcano, named Axial Seamount, last erupted in 1998, and the team of OSU scientists forecasted it would erupt again before 2014. Oregon State scientists say this marks the first-ever successful forecast of an undersea volcano.

The new eruption was discovered July 28 when scientists used a robot to find a new lava flow on the seafloor that was not present a year ago. Because only a handful of the earthquakes were detected from land, scientists did not initially believe there was an eruption.

Cool find!!!

Looks like they were able to determine that it erupted in April...just a couple of weeks after the Japan quake. Every time I hear about another undersea volcano off the coast, it makes me wonder how they could tie into the magma chamber theory.

I really like this quote: (taken from your above linked article)

"The acid test in science - whether or not you understand a process in nature - is to try to predict what will happen based on your observations," he says.

Read about that area a while back while looking into mesopelagic and abyssal fish. Its right next to the Channer Vent which exceeds 25cm/yr, the highest recorded spreading rate in the Nth Pacific.

Totally off topic but...interesting for some: Endosymbiotic infection by an unknown nanobacterium is possibly the cause of these massive fish.

reply to post by LexiconV


Wow....not so off topic. Very interesting. Thank you for the contribution!

BIG UPDATE!!!

Sorry, but this is going to be a long one.

Let me start by saying that there has been quite a bit going on lately with quakes and weather. I have gotten somewhat wrapped up in other things, but as always, I seem to be drawn back to the West Coast...and not just becuase I live here.

By chance and through discussions regarding other areas I have once again made some more connections and want to sum it all up here. First, I think I need to re-cap though. The thread has gotten long and I know there is a lot of info.

Before I get into all the technical stuff...I want to say that I feel very strongly right now that anyone living in California, Southern Oregon and Western Nevada should be on a heightened alert. Just be aware and make sure you are prepared incase of a large event.

I started this thread out by tying together a few different threads and theories. It has grown from there and I keep seeing more connections and evidence (in my mind ) of such. I am a very visual person, so I've got a bunch of maps and pictures to help with my points.

FIrst, I spoke of the theorized magma chamber under Washington State, the Deep tremor studies and a couple of off-shore volcanos. I then went on to connect some of the coastal dots and theorize that the Cascadian Subduction zone extends much further South than commonly accepted based on these things. I want to expand on that and talk about some new things that I believe are evidence of said subduction zone being active right now.

Here is a map of the West Coast Volcanos (per USGS)




Now....looking at that map, the Cascade Mountain Range and included volcanos extend down into Northern Oregon.


Here is a mapf of the accepted location for the Cascadian Subduction Zone:




source

SO....as the above maps illustrate, the subduction zone starts offshore, extending inland to where the cascade mountain range is...which ends with the twin sisters in Northern/mid Oregon. the zone continues South, ending pretty much where the San Andreas begins in Northern California.

As I have said before, I believe that the subduction zone does NOT end there, but continues SE in and through California.....and the that San Andreas Fault is a SYMPTOM of the stress caused by the subduction zone.

I found what I consider further proof of this when I realized the San Andreas was believed to have formed at about the same time we had our last Mega thrust earthquake here in pacific Northwest, further validating that the San Andreas was caused by the Cascade Subduction Zone.

To better illustrate how I think these all in together and what is happening with some swarms right now I have made a couple of maps.

First, a map of the San Andreas Fault.....I have added where I think the subduction zone continues and the two current swarms in Mammoth Lakes (Long Valley Caldera) and on the San Andreas...very near the last hisotric quake.




Those arrows I have drawn (sorry for the poor artwork ) are to indicate where the stress would be directed due to the upheaval and subsequent drop. (hope that makes sense)



So to get this you have to picture the land mass of the states (North American Plate) with the subducting plate off-shore pushing up under it, essentially causing the Western edge to fracture and threaten to drop. Now imagine the kinds of stress that would cause on the rest of the land mass......especially if you add in another crack through the middle; the New Madrid.

I made another map to show how I think that plays against each other (again arrows indicating stress)

(to make it more interesting, I am using a current quake map from USGS)




OKAY...(trying to keep this cohesive)....focusing back on the West coast.

NOW...you need to picture what is going on underneath


It is widely accepted that the Cascade Mountains and volcanos were caused by the subduction zone, AND that the volcanos are fed by the magma caused by the friction of the subduction zone. Lets look south of there.

In Oregon we also have the Newberry Caldera:
Newberry Caldera

Newberry volcano is a broad shield volcano located in central Oregon. It has been built by thousands of eruptions, beginning about 600,000 years ago. At least 25 vents on the flanks and summit have been active during several eruptive episodes of the past 10,000 years. The most recent eruption 1,300 years ago produced the Big Obsidian Flow. Thus, the volcano's long history and recent activity indicate that Newberry will erupt in the future.

In Southern Oregon we have Crater Lake:
crater lake

Crater Lake was formed after the collapse of an ancient volcano, posthumously named Mount Mazama. This volcano violently erupted approximately 7700 years ago. That eruption was 42 times as powerful as the 1980 eruption of Mount St. Helens. The basin or caldera was formed after the top 5000 feet of the volcano collapsed. Subsequent lava flows sealed the bottom, allowing the caldera to fill with approximately 4.6 trillion gallons of water from rainfall and snow melt, to create the seventh deepest lake in the world at 1,932 feet. -- Excerpt from: U.S. National Park Service Website: Crater Lake National Park, 1999

Then we get down into California and the one I want to talk about there is the Long Valley Caldera (which includes Mammoth Lake)
Long Vallery Caldera

Long Valley Caldera is located 20 km south of Mono Lake along the east side of the Sierra Nevada in east-central California. This area of eastern California has produced numerous volcanic eruptions over the last 3 million years including the massive, caldera-forming eruption 760,000 years ago. The most recent eruptions occurred just 500 to 600 years ago from vents along the Mono Crater-Inyo crater volcanic chain, which extends south from Mono Lake into the western part of Long Valley caldera

I want to also point out that the last swarm (in Long Valley) that included several 6+mag quakes and upheavel happened in may of 1980....the same month and year that Mount Saint helens had numerous quakes in the 4-5 range and ofcourse the fatefull eruption on May 18th, 1980. Coincidence???



So you can probably see by now where I am going with this. NO?? Okay.....here;

It is widely accepted that calderas are formed by either hot spots (plumes...like Yellowstone), or subduction zones. Long Vallery Caldera is a mystery. Well, not to me. Look again at the map above. Any of them, really. Using my theory that the subduction zone continues down. it very nicely ties in all those calderas AND the San Andreas (as a symptom).

NOW....lets look at the current swarms. First, the ones I posted about a short time ago at Crater Lake. Here, I'll re-post it. It was earlier this month:

Now we have some very impressive swarms occuring, like I said at Mammoth lakes (Long valley caldera) and on the San Andreas almost directly across from it, and near the last historical 7+ mag quake. Here are the latest quakes. I won't include more than the last day or two because it would just be too much:

First, Mammoth Lakes area:
Ugh....wont let me paste it. Here is a LINK. There are over twenty there for the last couple of days, but I can tell you there have been a lot more. I have watched several roll across GEE just while I have been typing this.

Next, the San Andreas:
Here is the LINK to that current list. There are just WAY too many...probably close to a hundred for just a couple of days.




So why am I so intrigued by this NOW? Well, there are some other indicators that there is possibly movement.

The Deep tremors. I just started a new thread on a new ETS (Episodic Tremor and Slip). The array team was taken by surprise because the deep tremors started up about three months earlier than they expected. The tremors are all clustered on the Northern end of the subduction zone. For example, take a look at todays. 536 tremors detected. That's quite a bit of a slow rumble on this end, don't you think? I have noticed some patterns over the past year with yin-yang. It makes me wonder if perhpas this isn't the next ETS......but another symptom of the stress building up on the opposite end? Thinking about it in that terms....you might then think that the current swarm at the Long Valley could be the subduction zone showing foreshocks and the San Andreas swarm yet another symptom of said pressure or upheaval.

I guess I am just asking those interested in this theory to take these ideas of the subduction zone and apply it to what we are seeing on the quake maps right now. I think that if you look at it in that light....you will be concerned. I know I am.


I'll close with another map. One that I have posted here several times, showing where I think the subduction zone is in relation to everything else. Please...keep an open mind. Look at this map:




and then look at THIS current quake map...and think about it.

I watched this one come across GEE about 3 minutes after I posted.

I'm telling ya...somethin's up

Hey hun... as always, BEAUTIFUL job explaining it all!!!!!

Did you see this article from Reuters regarding the swarm near Pinnacles National Monument? The sight of an "ancient volcano"!?!?!?

A cluster of mild earthquakes rumbled early on Saturday near Pinnacles National Monument, site of an ancient volcano in central California, and were widely felt in and around the Monterrey Bay area.

Hmmm...funny thing they don't mention that the largest quake ever recorded in California happened only 95 miles south of there on the the San Andreas:

This earthquake occurred on the San Andreas fault, which ruptured from near Parkfield (in the Cholame Valley) almost to Wrightwood (a distance of about 300 kilometers); horizontal displacement of as much as 9 meters was observed on the Carrizo Plain. It caused one fatality. A comparison of this shock to the San Francisco earthquake, which occurred on the San Andreas fault on April 18, 1906, shows that the fault break in 1906 was longer but that the maximum and average displacements in 1857 were larger.

Instances of seiching, fissuring, sandblows and hydrologic changes were reported from Sacramento to the Colorado River delta. Ground fissures were observed in the beds of the Los Angeles, Santa Ana, and Santa Clara Rivers and at Santa Barbara. Sandblows occurred at Santa Barbara and in the flood plain of the Santa Clara River. One report describes sunken trees, possibly associated with liquefaction, in the area between Stockton and Sacramento.

So in 1857, only 95 miles south of the current swarm there was a 7.9 quake. Largest ever recorded. There were signs of liquifaction, fissuring, seiching, sand blows and change in the water basins. It caused a RUPTURE of around 300 KM with displacement of 9 METERS.

So tell me.....how come this isn't being discussed in any of the articles about the current swarm???

Your not the only one that thinks something is about to happen

This site is predicting a good sized quake in the next 72 hours.

Highest earthquake risk cities in California; 5.8+ likely - risk of 6.3+ earthquake: August 28-31.

I would like your opinions on the little quakes that seem to be popping up in Idaho, Montana and Utah. I keep reading about Wa & OR but do any of you think the small quakes that are taking place near where I would describe as the western slope of the Rockies cause alarm? I look at the earthquake map and it seems that even the CO earthqwuake from last week was in line with the little ones popping up.

Yup...I've been watching those increase over the past couple of days. Not so sure about that...but if you think about it in relation to my theory...I would think that any increasing pressure on the subduction zone is going to have far-reaching affects.

I mean, think about it. It's what caused the cascade mountain range to form.
