Based on data from the International Institute of Seismology and Earthquake Engineering, Building Research Institute’s version of Utsu’s research Catalog of Damaging Earthquakes in the World (Through 2001) PC Edition and the USGS Centennial List 1900-2002, cross referenced with NOAA, NEIC, Geofon and EMSC

Apology

An apology again.
Apart from the Lists and the Timeline Charts this Blog is pretty well redundant now that Google maps has been changed to Google My Maps.
As I mentioned in February, Google will no longer show the KMZ/KML files these maps are created from.
I have begun the arduous task of transferring my research to Bing Maps, using ikiMaps to create the interactive maps and i-frames.
There is also an issue with WordPress. WordPress only recognizes Google i-frames, therefore both Google Maps and WordPress are not fit for my purposes on this project any longer.
Please refer to my new Blog, World Significant Earthquakes 314-2014 on Blogger.

Apology

Sorry folks, the maps are almost redundant (end of Feb 2015) due to Google changing their policy on Google Maps being able to read KMZ data (which is how these maps are created). You will already notice that the “view larger map” has already disappeared from below each map. I am looking at alternative formats.

Updates

1977 and 1978 have been updated, 1977 +4 and 1978 +3 newly found events from the Centennial List.
Graphs have been updated

Project Graphs

The graph below shows the number of 7+ quakes each decade.
Certainly looks like an increase in numbers since the 1990’s.

The following graph shows the number of 7+ events 1910-2011 on a yearly basis.
With another decade added it looks that the 1930’s, 1950’s and 1980’s were quieter compared to the other 4 decades.

These graphs will change as I complete more years going back.

Project Progress

It has been brought to my attention that most of the data pre 2000 is incomplete.

ER Engdahl and A Villasenor from the University of Colorado, Boulder, USA have published a comprehensive publication “Global Seismicity: 1900-1999” which brings together many secondary catalogues such as Gutenberg & Richter’s 1954 publication “Seismicity of the Earth”, which provides most of the larger earthquakes occuring between 1904 and 1952.
Other catalogues such as Abe (1981, 1984), Abe and Noguchi (1983), Bath and Duda (1979), Geller and Kanamori (1977), Pacheco and Sykes (1992) and Rothe (1969) are used in compiling the data.

I have run the data within the “Centennial Catalog” for two years, 1949 & 1950 beside the data I have already used and found another 17 and 21 respectively.
Therefore I will revise each year again, as time permits, until all data is complete, before moving on to pre 1910.
As the data is entered and published I will mark the bars on the charts with an red tip to show those that have been revised
