Over FIFTY earthquakes in the last several hours in Alaska and still counting

I've got to admit that I've been considering taking a fishing trip inland
I'm at 260 feet about 6 miles from the waters edge so I'm being silly. It would take a tsunami over 100 feet to even get near me I think. My home is beyond the area impacted in the 60's event.

This site: earthquake.usgs.gov...
and this site: www.aeic.alaska.edu...
and this one: www.avo.alaska.edu...
have any info you may want about earthquakes or volcanoes as well as links to other sites. They are posted on other pages but I thought they might help someone just tuning in.

Been doing some googling and have noticed that St Helens is "currently closed to climbing due to volcanic activity"

And there is also this:

Saturday, June 17, 2006 9:30 am PDT (1730 UTC)

MOUNT ST. HELENS UPDATE

Current status is Volcano Advisory (Alert Level 2); aviation color code ORANGE: Growth of the new lava dome inside the crater of Mount St. Helens continues, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.

There have been several earthquakes in the region of St Helens recently as well:

Then, we have Yellowstone, with it's newly erupting Geysers and reported ground swell over the last few years. There have also been Earthquakes in the region surrounding the Park:

MAP 3.9 2006/06/17 16:22:14 45.684 -111.828 5.0 WESTERN MONTANA

And of course, we have the constant string of Earthquakes from Alaska, California and the rest of the ROF. Seems to me, when you step back and look at the bigger picture, that something is afoot in the bowels of Mother Earth and we are yet to see what..

Fortunately the mother of us all moves very slowly. This may also be a good thing. Like releasing pressure from an over inflated tire could stop the blowout. I would not trust the government to tell us if they knew something was coming but the scientific community would find a way to let us know I think. I’ll cast my lot with them and if they say it is normal I’ll have to accept that. The same goes for HAARP.

earthquakes are fun!!!

There have been (3) today in the Rat Island area over 4.0 magnitude.

I wrote the USGS also and have attached their response below:

Hello-

Many or all of the recent Rat Island earthquakes are aftershocks to the M6.4 event which occurred June 13. That quake might have also triggered an earthquake "swarm" or cluster event, possibly triggered by magma movement or accelerated fault creep. Swarms are typically low-magnitude, and occur world-wide. In the U.S. there have been recent magma-induced swarms at depth within the Long Valley and Yellowstone calderas and beneath the Three Sisters volcanic center. Most swarms don't make the news.

Here is some information on the Rat Island earthquakes and earthquake clustering:

www.aeic.alaska.edu...
www.brightsurf.com...
www.google.com...
pasadena.wr.usgs.gov...
vulcan.wr.usgs.gov...

The Rat Island activity is not related to any activity in California, except they both occur on boundaries of the same plates. They are thousands of miles apart - too far for their small magnitudes.

There are no more earthquakes now than in past human history. When I was young we wouldn't have even known that they were occurring. With the Internet and advanced satellite communications, we can monitor more of the earth at increasingly sensitive levels, to it only appears that the number of earthquakes are increasing.

Tsunami warnings are triggered by very large earthquakes (usually M7.0 or higher) which occur under the ocean surface. For other tsunami information, go to: wcatwc.arh.noaa.gov...

We don't issue short-notice warnings of impending earthquakes. We do however give statistical predictions, such as what the chance is of a large event striking the Bay Area within the next 30 years.

You should find some interesting information at the aforementioned links. Best wishes.

Whether anything is really unusal or not, it is still interesting.

Anyone noticed how the earthquakes appear to be moving around the ROF and now Cali is getting alot of quakes?

Thing is, there must be a big slip somewhere along the line....

Well I just got back from my weekend and I see there are still "aftershocks" going on at Rat Islands. I don't think these are just aftershocks, not when it's almost constant quaking for days on end.

Are you taking note of all the quakes taking place on Earth since the "aftershocks"?

Have you find a pattern or a clue? Is it following a Fault line?

I am sure there must be "something", somewhere, to - at least - get an idea of what is taking place...

Have you tried to draw a line on a world map to join the locations where quakes are taking place? Just so check if they continue happening on the same lines or areas...
If they follow any order...

Who knows?

I´ve tried doing this map by locating the quakes taken place from the 14th to the 16th. Just a few days, as there were many... The results are amazing.

I really recommend doing it. If you have the time, it is worth trying.
It is interesting.

Why? I have followed this thread for days and have seen many wonderful maps issued by the seismic monitors around the world and they clearly show the areas of activity quite accurately.

Alaska is hot but a 4.0 or higher in Montana is MUCH SCARIER. Seeing as scientists have no real clue what would trigger a Yellowstone super eruption.....

Wonder if the tilted lake, increased geyser activity, the new HUGE magma dome under Yellowstone that forms a new caldera approx every 600,000 years [BTW its due now_javascript:icon('')
_javascript:icon('') is of any concern to anyone?

EQ's in uninhabited regions of Alsaka are interesting, but as the USGS says "normal" don't bother me as much as two above 3.0 quakes in the last few days in Yellowstone. Talk about Doomsday.... that caldera oughta take care of the Western US_javascript:icon('')

"Catastrophic eruptions occurred here about 2 million years ago, then 1.2 million years ago, and then 600,000 years a go. The latest eruption spewed out nearly 240 cubic miles of debris. What is now the park's central portion then collapsed, forming a 28- by 47- mile caldera (or basin). The magmatic heat powering those eruptions still powers the park's famous geysers, hot springs, fumaroles, and mud pots. "

vulcan.wr.usgs.gov...

It seems Alaska is still having greater than 4.0 quakes.

Latest one as of 10:51 pm cst from USGS

Yellowstone has also been having one area of swarms the last few days, though these are small.

From Live Science...awesome site...has loads of volcano info regarding Yellowstone and the calderas as well as other volcanos )including the Californian Volcano).

Also has great links on EQs as well - including Alaska with some interesting geplogically minded articles and images...

Really good site Enjoy!

Live Science

No word yet from the local news (Global) as to why it's not being covered at all. Maybe Monday - maybe not...will post if anything comes in

Hey guys,

Don't know what to make of this, neither I know if it's true or not, but found this mentioned on another forum and thought it would be worthfull to mention it any way. It's about california.

Hi Everyone,

Jack said the M4.7 earthquake in San Martin CA last Thursday may have satisfied his June 2, 2006 forecast for CA. However shortly after this event two large initial signals were detected that morning at 11:11am. Yesterday numerous smaller mains signals were received indicating another magnitude 3.0-to-4.0 earthquake south of the San Martin quake - first most likely date is June 18, 2006.

IMMEDIATE EARLY WARNING WARTHQUAKE ALERT ISSUED TODAY: The multiple signals detected on June 2, 2006 and the recent signals OVER THE PAST THREE DAYS share a common "most likely date" of June 18th, 2006 for a quake to occur. Jack has issued an immediate alert for a larger earthquake and/or confirming main signal to arrive as early as 4:20AM tomorrow morning .

Based on the multiple signals received on June 2, 2006 in additional to the most recent signals, the Specific forecast for Northern to Southern California issued on June 2, 2006 will remain in effect through June 27, 2006. Probability rate is * 90% percent.

* 90% chance of happening = 10% or 1-in-10 chance it won't happen.

Check back often for updates.

Take care,
Kim

Press release June 10

Possible date June 27. What should we make of this all?

[edit on 19/6/2006 by rai76]

Latest Count is 195 "aftershocks" going on steady for five and a half days now.

I'm in the process of emailing the Alaska Earthquake Information Center's people since quite a few of my previous emails to the USGS were replied with saying I should be asking them. No one has really answered me as to if this is normal for several straight days of quakes/aftershocks, they just gave me general answers regarding the area in which the quakes are happening. If I do not get any further with this last batch of emails I guess I'll throw in the towel and just wait and see what happens from here.

Also note on the AEIC home page they have the 6.3 quake that supposedly started all this as a 6.8.

WOW PANIC NOW EVERYONE!!!!

Run for the hills...... oh wait those hills were made by earthquakes....

ummm Head for the sea find an island.... oops no wait they are most likely volcanos and those tsunamis are killers...

Head inland yeah thats it! Only need to worry about catagory 5 tornados then... well unless global warming is true... then when the ice caps melt the central states will go back to being underwater.....

Ah I have it! Catch the next shuttle off this rock and find some real terra firma

funny zorgon !
Absolutly right on track

But seriously folks, I see most people here are forgettting one thing... Pick ANY seismicly active region in the world and do a little research on the number of quakes etc. that the region has had over the last year then over the last five years. I did that for Yellowstone and found amazing results.

www.seis.utah.edu...

Just take a look at the 1983 to present map

www.seis.utah.edu...

This shows that swarms of little earthquakes are a very common occurance. The news media is only interested in reporting things that are big news ie lots of death and destruction etc. The day to day incidents and explanations of smaller event are usually found in the scientific publications, which are more focused on that sort of thing.

The earth is a broken eggshell thats constantly moving and changing. Terra Firma is anything but. It is very likely that we are entering a more active period, possibly due in part to mans effect on the environment.

But until the Aliens land and offer us a lift to someplace safer
we are stuck here

Oh BTW I see no one mentioning the intensity of quakes and their threat.

Remember that the Richter scale is a logarithmic scale where each whole number is TEN TIMES greater than the previous one. This is a very important distinction. There are thousand of daily quakes that are below 3.0 that are generally not even recorded.

earthquake.usgs.gov...


Earthquake Severity

Richter Earthquake
Magnitudes Effects

Less than 3.5 Generally not felt, but recorded.

3.5-5.4 Often felt, but rarely causes damage.

Under 6.0 At most slight damage to well-designed buildings.
Can cause major damage to poorly constructed buildings
over small regions.

6.1-6.9 Can be destructive in areas up to about 100 kilometers
across where people live.

7.0-7.9 Major earthquake. Can cause serious damage over larger areas.

8 or greater Great earthquake. Can cause serious damage in areas several
hundred kilometers across.

source: www.seismo.unr.edu...


Being informed, aware of your surrounds and prepared is great, lack of knowlege always leads to needless fear and panic. But ummm if your living on a fault line or under Mount St Helen... have the car packed Those freeway jam up REAL fast


BTW you can buy a local area soil study map for your area from the county you live in. I did for greater Las Vegas area. cost me $20.00. Its VERY interesting... shows all the faults both major and minor, flood zones and subsidance zones.... [Mandalay Bay and the Luxor are right on a subsidance zone... and they wonder why they sank... Engineers..] My house is in the white zone

I've been really checking out the EQs on the west coast and it really is amazing just how frequently the earth rumbles under us without any of it being felt.

Until the invention and implimentation of the seismograph technology - we'd have been clueless as to what going on below.

I must admit it is a bit of an oxymoron having all of this information available. On the one hand it's amazing that we can chart the activity, make very crude estimations and forecasts based on historical and current data, and can monitor activity for signs of impending disaster. On the other hand it is a relatively new technology and there is still so much we do not understand about the data we collect - do swarms indicate a big one a'comin'? Can we forecast with any accuracy when a large quake might occur...it tends to raise more questions than it answers. Even most geologists and seismologists would be and have been hesitant to make cut and dried statement based on the data they collect.

We do know that clusters/swarms M3 or less happen with great frequency on all points along the ring of fire. Areas with the greatest pressure seem to experience more. California, Oregon, off the coast of the PNW in deep ocean, Japan, North Eastern China and Alaska, Indonesia and the list goes on...

Unlike the weather (which we can actually watch as systems are formed) we cannot yet make a chartable plot or path of great earth movements. Seismology is an advancing technology as well as geology, techtonics and whatnot...still a long way to go before we can accurately predict the behaviour of the earth. We can make guesstimates, but nothing concrete. Nothing that we can say...offer an emergency advisory about with confidence.

The last major EQ in California that leveled the freeway (can't recall the year M'bad) was charted right up to the day before and no one had any idea that a quake was going to occur beyond the magnitude of the quakes that preceeded it. They had suspected something was going on( small swarms around the area in the weeks preceeding) but nothing was concrete, and nobody wanted to be the one to say "here we go...we'll have a quake of estimated magnitude...".

Not because the data isn't reliable. Not because the experts aren't interested in saving lives. It boils down to not being able to decipher the signs we do get and missing out on the signs we either don't have the technology to record or have a firm 100% grasp of what has the makings of a major quake.

Volcanism is easier to chart and predict. We get clear visuals, in the form of tangible data, seismic activity, caldera measurements, changes in the domes and venting systems...we can "see" what's happening. Measure it and plot it and make fairly accurate predictions and estimations based on the data.

EQs are trickier.

So while nobody seems all that concerned about the Alaskan quakes - there is absolutely no way to say with complete certainty that we are/are not heading into a lead up to a major quake.

Very interesting stuff!! Great input from everyone!
