TheHeretic -> Is there a geologist in the house??? (2/13/2008 7:50:14 PM)

        One of my daily hit sites is the USGS recent earthquake map.  There has been quite a swarm of them in the past week in a sparsely populated region of Mexico, just across the border.

       http://quake.wr.usgs.gov/recenteqs/  

      It could be nothing, it could be the birth of a volcano, it could be the pre-shocks of something massive, where something massive is kinda overdue.

       Theories?

Get you tin hat ready



Rule -> RE: Is there a geologist in the house??? (2/13/2008 8:10:56 PM)

I am not a geologist. It seems to me merely a fault line event. It may be that as a consequence in the next couple of years there will be further shocks up north along the same fault line.

      Here's a closer view.

      There have been three over 5. since last week.  Earthquake prediction is notoriously inaccurate.

You don't need a geologist so much as you need a seismologist.

And even then you'll get more of an educated guess than a true prediction.

Living in the land of "shake and bake" leads to either constant anxiety, apathy, or readiness. But those along the New Madrid Fault need to remember that they are far more overdue than anyone in California.



TheHeretic -> RE: Is there a geologist in the house??? (2/13/2008 9:21:54 PM)

       That's why I prefer geologists to climatologists.  They freely admit we don't know.

Yeah, we`re floating on an ocean of super-heated molten lava.

So shit`s gonna happen.

There's a link on that site calling it an earthquake swarm.  So it caught the attention of the SCSN as well.  If this is just a interest or hobby, I think you could give yourself a pat on back for noticing it.

As far as what's up, not even the experts are guessing.

The birth of a volcano????      You really need to study up on the various types of volcanos and where volcanos form before jumping to such a conclusion.   There is NOTHING in the historical record to support the concept that this is such a birth......unless you count Hollywood movies as historical records.


For the record, I hold licenses as a professional engineer and a professional geologist.



TheHeretic -> RE: Is there a geologist in the house??? (2/13/2008 11:05:57 PM)

      Volcanoes come from molten rock finding it's way to the surface.  This is occuring in a geo-thermally active area.  My first apartment was quite literally across the street from a dormant volcano, so it's been an interest for some time.

Sooooo      WHERE does this happen?   What happens geologically to allow molten rock to find its what to the surface????




Heck, can you tell me how many different kinds of volcanos there are and where each different kind forms?


Why is Mt. Saint Helens different from Kilauea?

Global warming.  It causes earthquakes now.  Cancer, too, but what doesn't these days?

I think you were right the first time: it's nothing.

and muttling i bet u can pick the lottery numbers as well



snappykappy -> RE: Is there a geologist in the house??? (2/14/2008 12:29:27 AM)

so o great muttling since u r so educated u should know all of the answers why are u asking questions please give us the answers since u r a professional engineer and geologist




Aneirin -> RE: Is there a geologist in the house??? (2/14/2008 1:28:32 AM)

An interesting fact I found recently, is to do with the windows 98 operating system, as to setting a screensaver using text, typing in 'volcano', the resultant screen saver is a black background with words that start in the distance and gyrate towards the front, all the names of American volcanoes.

I was surprised at how many there are. I knew about Mt St Helens, coz when that last blew it's top, I lived in a town called St Helens.

Yes I can, but so can anyone who is willing to spend 15 to 30 minutes googling the subject of volcanos and vulcanology.



I would answer you question if I thought it were asked with honesty instead of a desire to be a troll trying to stir the pot.

Is it time to watch the movie 10.5 again?

Why is Mt. Saint Helens different from Kilauea?   


I'm not a geologist, but I do play one at archaeological sites sometimes.[:D] I guess the main difference that comes to mind is that St. Helens (and the other volcanoes in the Cascade Range) sits over a subduction zone where basaltic oceanic crust from the Juan de Fuca plate is diving under granitic North American plate crust while Kilauea and the rest of the Hawaiian volcanoes/islands result from basaltic oceanic crust of the Pacific plate passing over an upper mantle "hot spot".

So the Mt. St. Helens continental type volcanoes produce lavas that are predominantly rhyolitic (rhyolite is the extrusive, surficial form of granite) emitted from cinder cones and other pointy types of central vent cones (I don't remember what they're called), and the Hawaii type oceanic eruptions produce more viscous basaltic lava that is extruded at a more consistent rate, resulting in shield volcanoes (cuz they look like shields).  

That's all I got.

Bob

ps...(not aimed at you, Muttling) geologists, volcanologists, and climatologists all say "I don't know" about the same amount of times. Climatologists just draw more heat because their observations stand to affect the profits of people and corporations who don't give a fuck about you, me, your mom, or your kids.

(edited because I forgot to mention that basaltic lava is thicker than granitic.)
