I think we probably feel like there are more earthquakes happening because of the media and the way news reporting has advanced over the years

and we only ever hear about the earthquakes that cause devastation, so bringing in the talk about our technological ability to detect smaller earthquakes is irrelevant really

If it is the case that earthquakes around 7.0 magnitude or hire have remained constant, its the increase in population and subsequent increased impact that makes us take notice

The number of earthquakes greater than magnitude 4.0 in Southern California and Baja California has increased significantly in 2010. There have been 70 such quakes so far this year, the most of any year in the last decade. And it's only April. There were 30 in 2009 and 29 in 2008.

Seismologists said they are studying the uptick but cannot fully explain it.

you will find the same kind of data across the world, a report of increase in magnitude and in occurence.

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.

you left this part out faggot

However, this trend needs to be understood in relation to the increase in seismographs. Certainly, in the last 25 years, more lower intensity earthquakes have been noticed because of a general increase in the number of seismograph stations across the world and improved global communications. This increase has helped seismological centres to locate many small earthquakes which were undetected in earlier decades

are you retarded? ill put it in a big font so you can read it better.

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.

YILMAZ YOUR MUM SHOULD BE GHOSTED.

Why are we having so many earthquakes recently? Is it just that the media likes to report dramatic and tragic events, or has there been a quantitative increase? The graph below appears to tell a worrying story.

The graph legend states "USGS Worldwide Deadly&Destructive Earthquakes between Magnitudes 6 and 8" and plots data from 1900 to 2008. It appears to show a huge spike in major earthquakes starting some time around 1999

What is this argument even about?

/

Got fam out in Tokyo, they're alright, said it was like it is on tv, really big shakes then constant aftershock

They have tremors all the time though, when I stayed there and got up the next morning they'd be saying "Did you feel that quake last night?"

I'd slept through it :mellow:

Rescuers in Japan have called in Elton John, George Michael and Graham Norton to help search through the rubble for injured victims. Their work could prove invaluable as they are experts in seeing japs eyes covered in sh*t.
