Earthquakes - talk me down here . . .

[Richard D]

I was talking with a friend about earthquakes and he said that they've been increasing in frequency. I doubted that. He pointed this out: http://en.wikipedia.org/wiki/List_of_20th_century_earthquakes and this: http://en.wikipedia.org/wiki/List_of_21st_century_earthquakes, and they have been dramatically increasing over the last decade from a couple a year to a great many more than that.

Any ideas about this? Makes me almost a believer in 2012.

1. Scientists say earthquake frequency not rising

Hope this helps! :hi:

2. It's funny that the headline of that story addresses that very concern

Turkey earthquake kills 51; scientists say earthquake frequency not rising

Probably everyone is thinking the same thing with these big quakes one right after the other. And this is reassuring, in a way:

"According to the US Geological Survey, the earth usually has one magnitude-8 or higher earthquake per year, some 17 quakes between 7 and 7.9, and roughly 132 earthquakes a year with a magnitude of between 6 and 6.9 – like the most recent quake in Turkey.

"The recent earthquakes are not abnormal in frequency, scientists say, but have received more attention because of the loss of human life."

5. That and I imagine our ability to detect earthquakes around the globe

has increased substantially over the century

and even if they were increasing, frequency of earth quakes over an unspecified time interval would follow some sort of random distribution

3. Not more quakes, just more people in quake zones

4. I posted an article suggesting something significant may be happening.

It was all debunked in the thread, with good links to prove it.
