Earthquake Frequency Up 133% In 2010

There’s been a sharp increase in the number of earthquakes all over the world in the first six months of 2010. Earthquakes with magnitude between 5 and 7 on the Richter scale is up 133%, compared to average frequency over the last hundred years.

“We will see if the trend continues as the rest of 2010 plays out.”

Modern Survival Blog


The Modern Survival Blog have updated their statistics on earthquake frequency for 2010, analyzing data back to 1900. During the month of June the overall earthquake numbers have brought the percentages down a bit, although it’s still well above average.

Earthquakes between magnitude 5.0 and 6.9 are still up and occurring 133 percent more frequently than average statistics so far during 2010, according to the recent analysis by the Modern Survival Blog.

Earthquakes between magnitude 5.0 and 9.9 are occurring 125 percent more frequently than average statistics so far during 2010.

The last time MSB analyzed the 2010 data (during the end of May), the overall frequency of occurrence was somewhat higher than this analysis. In other words, during the month of June the overall earthquake numbers have brought the percentages down a bit, although still above average as noted.

“We will see if the trend continues as the rest of 2010 plays out,” the blogger writes.

The data used in the analysis has been collected from the USGS (United States Geological Survey) going back to to the year 1900.

“I have averaged the number of earthquakes since 1900 in each magnitude range (5.0 to 5.9, 6.0 – 6.9, 7.0 to 7.9, and 8.0 to 9.9), and have also averaged the same data over the last 10 years. I then compared this data with the current earthquake statistics so far in 2010.”

Earthquakes of magnitude 4.9 or less, were not analyzed for the following reasons.

* Low magnitude earthquake detection technologies of the early 1900’s were not what they were decades later, and certainly not as advanced as today

* Low magnitude detection technology improvement would skew the numbers as though they’ve increased significantly in more recent times

* They cause little or no damage

(Earthquakes above magnitude 4.9 were fairly easy to detect, even a century ago).

The Results

*

*

* Earthquakes of magnitude 5 – 5.9 have increased by 127 percent compared with same range of earthquakes over the last 10 years.

*

* Earthquakes of magnitude 5 – 5.9 have increased by 149 percent compared with same range of earthquakes since the year 1900.

*

* Earthquakes of magnitude 6 – 6.9 have increased by 126 percent compared with same range of earthquakes over the last 10 years.

*

* Earthquakes of magnitude 6 – 6.9 have increased by 136 percent compared with same range of earthquakes since the year 1900.

*

* Earthquakes of magnitude 7 – 7.9 have increased by 139 percent compared with same range of earthquakes over the last 10 years.

*

* Earthquakes of magnitude 7 – 7.9 have increased by 122 percent compared with same range of earthquakes since the year 1900.

*

* Earthquakes of magnitude 8 – 9.9 have equaled the average of 1 compared with same range of earthquakes over the last 10 years.

*

* Earthquakes of magnitude 8 – 9.9 have equaled the average of 1 compared with same range of earthquakes since the year 1900.*

Katla Update

After 61 earthquakes in the Katla area in Island since May 17th, the giant volcano seems to have taken a little break in June.

However another earthquake was reported yesterday, June 30th.

The Icelandic Met office lately has been adding earthquake’s that are late, as much as 24 – 36 hours late, to their 48 hr. map, according to the Modern Survival Blog.

“3 EQ’s popped up Saturday indicating they were 36 hours old – but were not there earlier – they also added one on Sunday, already 12 hours old, added another on Wednesday about 24 hours old – strange. We’ll see what they decide to do today…”

  2. Please check out my website http://www.tectonicplates.ca/ that contains my theory on the increase in earthquakes world wide; but primarily in the South China Sea region. My theory in a nutshell is that the warming water of the planet is resulting in thermal expansion of the tectonic plates in the south china sea region: Scroll way down to the bottom of the very long page and there is a chart indicating the increase of earthquakes in the area of Indonesia due to the very shallow south china sea warming and causing thermal expansion of the plate; about half way down my web page I show the assumptions and calculation as below. Check it out! It is the one stop you need for all your tectonic plate info and to think out of the box.

    Tectonic Plates are made from Basalt or Granite: Given a coefficient of thermal expansion of (8 X 10-6/ 0C) for Basalt. Assuming a 0.310C temperature change (very conservative considering the depth.) and a 2000Km length experiencing the temperature change (There is a shelf 2000 Km long that is no deeper than 100m, allowing for the warm surface water to reach the tectonic plate.):

    The Math:
    Change in length Basalt = (8 X 10-6/ 0C)(2000Km)(0.310C)
    Change in length Basalt = 0.00496 Km or 4.96m. increase in length.

    Or given a coefficient of thermal expansion of (9 X 10-6/ 0C) for Granite, a 0.310C temperature change and a 2000Km length experiencing the temperature change:

    Change in length Granite = (9 X 10-6/ 0C)(2000Km)(0.310C)
    Change in length Granite = 0.00558 Km or 5.58m. increase in length.

    Note: The above calculation uses only a 0.31-degree water temperature change and calculates only the linear thermal expansion; if the area thermal expansion were calculated it would double the expansion value.

    This is a new theory that I am hoping will be accepted, although my website was created in a hurry and looks a bit unprofessional, the theory I believe to be sound. I have discussed the theory with Rock Mechanics PhD, several Geologists and Engineers that believe it is possible. Cheers… and please email your thoughts to the address at the top of the website.

      Thanks lot for that interesting info!

      I think your theory makes sense, and I will probably write a little piece about it, if you don’t mind 🙂

      Right now I’m thinking; 0,31 degree water temperature – what if we add a couple of underwater volcano eruptions?

      Please inform me if you discover other related stuff.

    Great story! Lots of work went into this one. I appreciate that. I see so many story with little content. Come check out my story and let know what you think…?
