Several of us here watch the status of earthquakes on a continuous. Usually, when I crank up my computer in the mornings, I use the earthquake page to open things up. So.............WOW, today when I do this, it shows 583 earthquakes 2.5 and above during the past 7 days. That number is probably about 3X the average number I usually see.

Yes, the number does vary considerably, but during the two or three years I have been watching it, this is considerably above the highest I have seen - 400+ is the highest I have seen. When I look through the list of quakes, it is mind boggling when we see how many quakes have hit areas of Puerto Rico during this time, and includes one at 6.4 magnitude. In counting through the list of quakes around Pureto Rico for the past 7 days, there are about 390 total quakes, with 299 of them folowing after the 6.4 event.

So, that does pretty much explain where the high number is coming from. I do wonder about whether or not there is any "synergism" of quake events around the globe - ie a quake here causes a quake over there, and a quake there causes............and on and on??

Here is a link to the quake data I am referring to.

I think that only happens in a relatively small area and with the larger earthquakes.

Earthquakes are driven by the Thermal currents within the Earth...

It looks much like a 3D Weather Map within the Earth, Not only rising along ridges in our Oceans
and sinking again along the trenches like being recycled land but there are also Rotations involved,
much like that having high & low pressure areas, just as in our weather in our atmosphere
above the Earths Crust.

The movements of plates etc. are as complicated, as the patterns of "thermal eddies" within the earth.

Perhaps I should say as involved rather than complex.

Where thermodynamics are involved we also find thermal convections, caused by many interacting
phenomena within the environment.

Just one of the areas in trying to understand and predict earthquakes just as when trying to predict
long range forecasting...

http://en.wikipedia.org/wiki/Weather_forecasting

QuoteWeather forecasting is the application of science and technology to predict the state
of the atmosphere for a given location. Human beings have attempted to predict the weather informally
for millennia, and formally since the nineteenth century.

Weather forecasts are made by collecting quantitative data about the current state of the atmosphere
on a given place and using scientific understanding of atmospheric processes to project how the atmosphere
will evolve on that place.

Once an all-human endeavor based mainly upon changes in barometric pressure, current weather
conditions, and sky condition, weather forecasting now relies on computer-based models that take
many atmospheric factors into account.

Human input is still required to pick the best possible forecast model to base the forecast upon,
which involves pattern recognition skills, teleconnections, knowledge of model performance,
and knowledge of model biases.

The chaotic nature of the atmosphere, the massive computational power required to solve
the equations that describe the atmosphere, error involved in measuring the initial conditions,
and an incomplete understanding of atmospheric processes mean that forecasts
become less accurate as the difference in current time and the time for which the forecast
is being made (the range of the forecast) increases.

The use of ensembles and model consensus help narrow the error and pick the most likely outcome.

There are a variety of end uses to weather forecasts. Weather warnings are important forecasts
because they are used to protect life and property. Forecasts based on temperature and precipitation
are important to agriculture, and therefore to traders within commodity markets.

Temperature forecasts are used by utility companies to estimate demand over coming days.

On an everyday basis, people use weather forecasts to determine what to wear on a given day.

Since outdoor activities are severely curtailed by heavy rain, snow and the wind chill,
forecasts can be used to plan activities around these events, and to plan ahead and survive them.

So a similar map can be constructed showing the Thermal weather within the Earth ....

... if we have the data.

I have come across some examples of this within sections of the Earth, but I don't know
if a Complete map of the Earth has been mapped regarding this Phenomena or is available..

Z might know ?

I don't think that's possible with the current (as far as I know) technology, as we would need temperatures and pressures at all depths to have the same kind of data we use for weather forecast.

Could you point me to one of those examples? Thanks in advance. :)

Shifting House at present but when I get a chance I will try and find some links for you.

It's some months back I came across this info.

There wasn't a lot on it but it does show scientists are making an effort to map this phenomena.

It just goes to show we have hardly scratched the surface of Knowledge....  :)


It amazes me how the "human species" desperately over rates out level of knowledge,
when really we know very, very little about anything..

Realistically; We are about to "Stand at the Dawn of knowledge" !   :)

Still that's the Adventure ...  "Discovery"

One aspect of earthquakes that may be of interest.

Check how many major quakes per year over a span of several decades, like from 1900 onward.


It's an eye opener.  :o

Sometimes we have more than 100 a day in NZ but what is published is about 70 Earthquakes a day in NZ a lone...
(This varies of course.)

Most below 3.0 Magnitude while others are so Deep... 300 Km+ we don't feel them...

If the average day in NZ was say 70 earthquakes a day then it would average out / week 490 earthquakes

and 176,400 / year and.... 17,640,000 / hundred years... just in NZ.... a very small country ....  :)

Where can we "check it out"? That would help...

I used my local (Seattle) library back in the 1970's, , , ,

I read this and wondered how many of our younger members have never even stepped inside of one. Since the internet has come on line Libraries have gone the way of the dino. I think they have them here but I have never seen one yet. Most students use the large book stores as one. It is a funny site to see. they are allowed to read the book on site. So they sit all over the floor reading books so they don't have to pay for them.

When I was in school I used to almost live in a library at times.

Why? Because you are you.   :)

One thing about doing research through books was that it was very difficult to alter the information from generation to generation. Because books stayed around for a very long time. Today it takes a mere click of the mouse and now it never was.
