earthquakes were way less common 3000 years ago, do your own research on earthquake time lines for any given country you stupid cunts

lol at thinking there are accurate readings dating from 3000 years ago...

all this sh*t was proved in the end of the world thread.... earth quakes have not been getting more frequent or stronger, they are jut getting reported more

not even saying its an end of the world thing but i dont know how ppl are saying that we have better recording equipment now

than 20,50,100, yrs ago :/ its not the equipment its the occurence not the live detection that matters

so its not as if bare earthquakes happened 200yrs ago and were not recorded of course they were.

thats how we know of earthquakes that happened 2000 yrs ago.

if reports prove that more have happened recently its bcos more HAVE happened recently, not using better equipment

as if there was no means of transmitting information 2000yrs ago

what are you on about bro

you think they recorded every earthquake that happened 2000 years ago in countries most people didn't know existed in a little notebook that has somehow lasted the test of time and is still viewed by scientists today? seems pretty unlikely to me.

until about 600 years ago, barely anybody knew about america, and that's a pretty big f*ck*ng island. you think in the year 250 they were recording all the earthquakes that happened there too?

earthquakes have happened in pretty much the same areas for the last few centuries.

earthquake history is recorded by those countries and places where they occured

and thats where we get the records from about how and when they happened going back many centuries

dunno what you';re even trying to imply cos its quite common sense.

about there's better detection equipment. what a stupid analogy

Are Earthquakes Really on the Increase?

We continue to be asked by many people throughout the world if earthquakes are on the increase. Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.0 or greater have remained fairly constant.

A partial explanation may lie in the fact that in the last twenty years, we have definitely had an increase in the number of earthquakes we have been able to locate each year. This is because of the tremendous increase in the number of seismograph stations in the world and the many improvements in global communications. In 1931, there were about 350 stations operating in the world; today, there are more than 8,000 stations and the data now comes in rapidly from these stations by electronic mail, internet and satellite. This increase in the number of stations and the more timely receipt of data has allowed us and other seismological centers to locate earthquakes more rapidly and to locate many small earthquakes which were undetected in earlier years. The NEIC now locates about 20,000 earthquakes each year or approximately 50 per day. Also, because of the improvements in communications and the increased interest in the environment and natural disasters, the public now learns about more earthquakes.

According to long-term records (since about 1900), we expect about 17 major earthquakes (7.0 - 7.9) and one great earthquake (8.0 or above) in any given year.

i'm not sure what yuo're saying here - that scientists/geologists today are able to look back and estimate there was an earthquake in X location 1700 years ago? cos that's believeable. What's not believable is that some red indian tribe witnessed an earthquake in the year 812 and recorded it - that's just silly

Q: Why are we having so many earthquakes? Has earthquake activity been increasing? Does this mean a big one is going to hit? OR We haven't had any earthquakes in a long time; does this mean that the pressure is building up?

A: Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.0 or greater have remained fairly constant throughout this century and, according to our records, have actually seemed to decrease in recent years.

There are several reasons for the perception that the number of earthquakes, in general, and particularly destructive earthquakes is increasing.

1) A partial explanation may lie in the fact that in the last twenty years, we have definitely had an increase in the number of earthquakes we have been able to locate each year. This is because of the tremendous increase in the number of seismograph stations in the world and the many improvements in global communications.

In 1931, there were about 350 stations operating in the world; today, there are more that 4,000 stations and the data now comes in rapidly from these stations by telex, computer and satellite. This increase in the number of stations and the more timely receipt of data has allowed us and other seismological centers to locate many small earthquakes which were undetected in earlier years, and we are able to locate earthquakes more rapidly.

The NEIC now locates about 12,000 to 14,000 earthquakes each year or approximately 50 per day. Also, because of the improvements in communications and the increased interest in natural disasters, the public now learns about more earthquakes. According to long-term records (since about 1900), we expect about 18 major earthquakes (7.0 - 7.9) and one great earthquake (8.0 or above) in any given year. However, let's take a look at what has happened in the past 32 years, from 1969 through 2001, so far. Our records show that 1992, and 1995-1997 were the only years that we have reached or exceeded the long-term average number of major earthquakes since 1971. In 1970 and in 1971 we had 20 and 19 major earthquakes, respectively, but in other years the total was in many cases well below the 18 per year which we may expect based on the long-term average.

2) The population at risk is increasing. While the number of large earthquakes is fairly constant, population density in earthquake-prone areas is constantly increasing. In some countries, the new construction that comes with population growth has better earthquake resistance; but in many it does not. So we are now seeing increasing casualties from the same sized earthquakes.

3) Better global communication. Just a few decades ago, if several hundred people were killed by an earthquake in Indonesia or eastern China, for example, the media in the rest of the world would not know about it until several days, to weeks, later, long after such an event would be deemed �newsworthy�. So by the time this information was available, it would probably be relegated to the back pages of the newspaper, if at all. And the public Internet didn't even exist. We are now getting this information almost immediately.

4) Earthquake clustering and human psychology. While the average number of large earthquakes per year is fairly constant, earthquakes occur in clusters. This is predicted by various statistical models, and does not imply that earthquakes that are distant in location, but close in time, are causally related. But when such clusters occur, especially when they are widely reported in the media, they are noticed. However, during the equally anomalous periods during which no destructive earthquakes occur, no one deems this as remarkable.

A temporal increase in earthquake activity does not mean that a large earthquake is about to happen. Similarly, quiescence, or the lack of seismicity, does not mean a large earthquake is going to happen. A temporary increase or decrease in the seismicity rate is usually just part of the natural variation in the seismicity. There is no way for us to know whether or not this time it will lead to a larger earthquake. Swarms of small events, especially in geothermal areas, are common, and moderate-large magnitude earthquakes will typically have an aftershock sequence that follows. All that is normal and expected earthquake activity.

ALL THAT SAYS IS THAT WE NOW HAVE THE ABILITY TO DETECT MORE EARTHQUAKE OCCURENCES, ITS DOESNT SAY THEY ARE NOT ON THE INCREASE, NOR THAT THEY ARE..SO POSTING THIS TO DISPROVE WHAT SOME PEOPLE ARE SAYING ABOUT MORE EARTHQUAKES HAPPENING IS USELESS

IT JUST GIVES A PERSPECTIVE THAT 'ATTEMPTS' TO EXPLAIN WHY THERE ARE MORE EARTHQUAKES BEING REPORTED..

/ STOP POSTING sh*t.

I CAN POST STATS AND GRAPHS TOO

Below is a graph showing how the number of all magnitude earthquakes has grown over recent years. Although we are primarily concerned with long term trends for larger magnitude earthquakes in this report, it is worth noting the trend as it applies to all earthquakes - whether large or small, over a 30 years period or so from the mid-1970s.
