       The chart and map data on this Web page were generated using Gnuplot.exe based graphics routines linked with an advanced version of the Perl language Earthquake And Tornado Data Evaluation Computer Program.  One goal of this earthquake forecasting program development effort is to make .exe versions of those programs available for free use by governments and researchers around the world.

       With the chart on this Web page, where there is a plot line peak at some longitude it means that the electromagnetic pulse (EM signal) or earthquake associated with that plot line was a good match for earthquakes that occurred in the past at that longitude.

       With the maps, where there is a plus sign (+) at some location it means that the EM signal or earthquake associated with the map was a good match for earthquakes that occurred in the past at that location.

THE  OCTOBER  31,  2007  SAN  FRANCISCO  AREA  EARTHQUAKE

       On October 18, 2007, based on EM signals detected that month an e-mail earthquake warning was circulated to earthquake researchers and disaster mitigation personnel around the world.  It stated that some of the possible locations appearing in the data tables were along the 121W, 59E, and 149E longitude lines.  Later that day information arrived stating that another earthquake forecasting researcher was expecting strong seismic activity in the San Francisco area.  That researcher’s public forecast can be found at the following location:

       The earthquake forecasting computer programs were then used to compare two of the EM signals detected in October with three destructive California earthquakes (two past San Francisco area ones and one in the Los Angeles area).  Data the programs generated can be seen below in Chart 1.

       Line plots 1 and 2 for the two San Francisco earthquakes look fairly similar indicating that they were probably triggered by somewhat similar sun and moon gravity related forces.  Line plots 3 and 4 for the two EM signals also look similar to those earthquakes.  And that indicated that the signals might have been generated in connection with approaching seismic activity in the San Francisco area.

       Line plot 5 for the Los Angeles earthquake is quite a bit different looking from both the San Francisco earthquake line plots and the two EM signal line plots.

       On October 25, 2007 another e-mail earthquake notice was circulated advising researchers etc. to watch for possible seismic activity in the San Francisco area.  And on October 31, 2007 the following earthquake occurred.  It was reportedly both mildly destructive and the most powerful one to occur in that area in almost twenty years.

(U.S. National Earthquake Information Service Data)

       At a later date when the Gnuplot.exe graphics capabilities were expanded Maps 1 and 2 shown below were generated using those October EM signal data.  The plus signs on the maps indicate that both of the EM signals were good matches for U.S. West Coast earthquakes that occurred between January of 1990 and early February of 2008.

This is an experimental Web page that will probably be discontinued at some point in time.
