THE  SIGNIFICANT  EARTHQUAKES  DISCUSSED  ON  THIS  WEB  PAGE

       This Web page contains picture files and some explanation data for quite a few Significant Earthquakes that occurred during the year 2010.  The Archives - Older Web page displays information for significant earthquakes that occurred in earlier years.  In some cases two or more earthquakes are displayed on the same chart.  Additional earthquakes will be added to this Web page as time permits.  Web Site visitors can also try contacting me at seismic@ix.netcom.com to request that a particular earthquake be added to the list.

       With most or all of these earthquakes there are two charts.  The first one shows what the Data.html Web page Chart A data chart looked like just before the earthquake occurred, or what it would have looked like had the Etdprog.exe earthquake forecasting computer program been running in its present form at the time of the earthquake.  The second chart in each set, displayed just below the first one, is the same chart with some added data and some observation and explaination information for both of the charts.

       Site visitors can examine these charts and determine for themselves if shortly before any of the earthquakes displayed here occurred, the information on the chart associated with it would have been sufficiently clear and accurate to determine that the earthquake could be approaching.

2010/07/07 23:53:33 33.41N 116.48W 12 5.4 Southern California

       This earthquake's strong longitude line peak at 116 W shows that it was an excellent match with other earthquakes that occurred at that longitude.  Additional comments might be added at a later date.

2010/07/04 21:55:52 39.70N 142.52E 24 6.4 Japan Area

       It appears that the Etdprog.exe computer program did a good job of detecting the approach of the July 4, 2010 earthquake in the Japan area.  Strong longitude line peaks can be clearly seen at 143 E longitude on recent Time Window lines.  And there were no line peaks at that longitude on earlier Time Window lines.

2010/06/30 07:22:29 16.52N 97.76W 20 6.2 Oaxaca, Mexico

       One or more individual EM Signals appeared to be linked with this earthquake.  However, the line structure in this averaged EM Signal type Chart does not provide any indicators that the earthquake was approaching.

2010/06/15 04:26:58 32.69N 115.92W 7 5.7 Southern California
2010/04/04 22:40:41 32.12N 115.30W 10 7.2 Mexico

       The Etdprog.exe computer program did an extremely good job of detecting the approach of the June 15, 2010 earthquake in Southern California.  Strong longitude line peaks can be clearly seen at 116 W longitude on recent Time Window lines.  And there were no line peaks at that longitude on earlier Time Window lines.  There is also a strong line peak at 141 E that matches that line peak on the earthquake line.  The Data.html Web page Chart stored on that Web page on June 13, 2010 had even stronger and clearer line peaks at 116 W.  This earthquake is probably regarded as an aftershock for the powerful one that occurred in that area on April 4, 2010.  And so for research purposes that earlier earthquake is also being displayed on the following chart.

2010/05/20 22:16:33 9.37N 84.25W 23 5.9 Costa Rica
2010/05/19 04:15:43 5.06S 77.55W 126 6.0 Northern Peru

       The Vanuatu, Peru, and Costa Rica earthquakes, and the EM Signals detected during the time between the earthquakes appear to represent a very complex matter.  Data being presently evaluated suggest that the three earthquakes and the EM Signals might have all been linked in some manner.  The EM Signals were probably pointing to the approach of the Vanautu earthquake.  And because of the way the Etdprog.exe program does its calculations, the longitude line peaks at 174 W and 96 E might have been pointing to the approach of the Costa Rica earthquake (84 W + 90 and 84 W - 180).

2010/05/16 05:16:11 18.40N 67.07W 113 5.8 Puerto Rico

       On the May 5, 2010 Time Window line and earlier Time Window lines there is a strong longitude peak around 67 W where the fairly powerful May 16, 2010 Puerto Rico area earthquake occurred.  And it is possible that those line peaks were pointing to the approach of the earthquake.  Those line peaks are not visible on the 15, 45, and 90 day Time Windows.  It is possible that the approaching earthquake was no longer generating EM Signals.  Or, it might be that the strong line peaks around 120 W were overpowering the 67 W area signals.  The earthquake itself does not have a strong line peak at 67 W.  And that can make it more difficult for the Etdprog.exe computer program to spot the approach of the earthquake.  There is a strong earthquake line peak at 122 E.  And smaller line peaks appear at that longitude on some of the Time Window lines.  That might indicate that the computer program was able to detect some signs that the earthquake was about to occur.

2010/04/30 23:16:30 60.52N 177.72W 16 6.0 Bering Sea
2010/04/30 23:11:44 60.55N 177.87W 15 6.4 Bering Sea
2010/04/30 23:10:24 60.62N 177.90W 14 4.3 Bering Sea

       There is an excellent correlation between the earthquakes' longitude (178 W) and the March 20, 2010 through April 29, 2010 Time Window line peak longitudes.  That suggests that the Etdprog.exe computer program was probably able to detect the approach of the earthquakes.  There is also a good correlation between the 15 day Time Window line peak structure and the line peak structure of the earthquakes.  The 15 day Time Window and the earthquakes have a fair amount of line structure in the 115 W to 125 W area.  The reason for that is unknown.  But it might have something to do with the tremendously powerful April 4, 2010 earthquake in Mexico that occurred at 115 W.  It is interesting to note that the Bering Sea earthquakes have that line peak structure around 115 W but not at 178 W.  And, the Mexico earthquake, also displayed on this Web page, has a large line peak around 175 W, but not at 115 W.

2010/04/04 22:40:41 32.12N 115.30W 10 7.2 Mexico

       Although they are not appearing on this chart, EM Signals detected within a few days of the following Mexico earthquake appear to have been pointing to its approach.  And as the chart shows, some EM Signals detected in January of 2010 might also have been pointing to its approach.  Because of the way the Etdprog.exe program does its calculations, the January Time Window chart peaks at 155 E might have been linked with the earthquake as well.

2010/03/12 17:32:09 34.88N 141.63E 19 5.8 Japan Area

       The following 6.5 magnitude earthquake was strongly felt in Japan.  It appears from the strong peak at 142 E that the Etdprog.exe computer program was easily able to detect the approach of the earthquake. This earthquake is discussed in more detail on the Archives - Interpret Web page.

2010/03/08 02:32:35 38.85N 39.94E 10 6.0 Eastern Turkey

       The following destructive Turkey earthquake reportedly claimed about 60 lives.  Line #15 shows that there are relatively few earthquakes at 40 E longitude in the earthquake database file.  So the program might not have been able to find any at that  longitude for comparisons.  Because of the way that the Etdprog.exe computer program does its calculations, the peaks at 140 W and 130 E might have been pointing to the approach of the earthquake.

2010/03/04 00:18:52 22.90N 120.82E 23 6.4 Taiwan

       The following earthquake was strongly felt in Taiwan.  There was a fair amount of building damage.  And scores of people were injured.  It appears from the moderately strong peak at 121 E that the Etdprog.exe computer program was probably able to detect the approach of the earthquake. This earthquake is discussed in more detail on the Archives - Interpret Web page.

2010/02/27 06:34:15 35.84S 72.71W 35 8.8 Chile Area

       The following extremely powerful and fairly destructive Chile earthquake created a tsunami (tidal wave).  And it claimed hundreds of lives.  This earthquake is discussed in more detail on the Archives - Interpret Web page.

2010/01/12 21:53:10 18.45N 72.44W 10 7.0 Haiti Region

       The following Haiti earthquake was incredibly destructive.  It claimed hundreds of thousands of lives.  The chart shows that Etdprog.exe computer program might have detected the approach of the earthquake.  Strong EM Signals were also reportedly detected in the Haiti area just before the earthquake occurred.

2010/01/10 00:27:39 40.64N 124.76W 22 6.5 Offshore Northern California

       It is possible that longitude peaks associated with the following approaching California earthquake are appearing on the chart a little to the east of where the earthquake actually occurred.
