This Web page is presently undergoing a major update.
The present version of this Web page is intended largely for demonstration purposes.
The next update will contain the latest actual data.
Earthquake forecasters and researchers who do not
already have a good understanding of the Table Data on this Web page should review
the explanation information in the the Individual EM Signals section of the Table-Data Web page.
The Table Data are table
types
of representations of the Individual EM Signal chart lines that can be
found on the EMS.png and EQ-EMS.png charts displayed on the Data.html
Web page. Those charts and these tables are intended to help
earthquake forecasters and researchers identify patterns in the data
that might enable them to determine when Significant Earthquakes are
approaching for locations that are of interest to them.
This Web page's Table Data can be compared with similar data for Significant Earthquakes that can be found on the
Significant-Earthquakes.html Web page. The earthquakes on that
Web
page go from the present back to the start of 1973. Most of those
earthquakes resulted in fatalities. Also on that Web page are 8.0
and
higher magnitude earthquakes going back to the start of 1973 plus a
number of additional earthquakes that are important
for research purposes.
The following section related to
the devastating January 12, 2010 Haiti earthquake is an example of how
the Table Data for Individual EM Signals can be helpful to earthquake forecasters as they attempt to determine when and where an expected earthquake might be about to occur. This matter is discussed in much more detail on the Table-Data Web page.
THE ABSOLUTELY CATASTROPHIC JANUARY 12, 2010 HAITI EARTHQUAKE
That calamitous
earthquake reportedly resulted in the loss of more than 200,000
lives! One survivor's personal account of the disaster can be
found on the Earthquake Forecasting Breakthroughs Web page.
The chart below displays the data
line shape for the especially high intensity EM 8 Signal that was
detected a little more than 35 hours before that catastrophic
earthquake. EM 9 signals are the strongest signal that can be
detected. They are detected only a few
times a year at most. The somewhat less intense EM 8 signals such as the one on the chart might be
detected once every few months.
The data line shape
for the Haiti earthquake can be seen just below the data line for the
EM 8 Signal.
Those two data lines are quite similar in shape.
That indicates that the EM Signal was likely associated with the
approach of the following day's Haiti earthquake. And as can be seen, one of the
main line peaks for the EM Signal data line was located right around 73 W
where the earthquake eventually occurred.
That especially high intensity EM Signal data line was likely accurately indicating that a Significant Earthquake might be about to occur in some fault zone along the 73 W longitude line.
The line peak heights on Data Line # 3
provide information regarding how many of the more than 110,000 earthquakes
in the earthquake database file going back to the beginning of 1973
occurred at various longitudes. That information is important when
the longitudes of the line peaks on EM Signal and earthquake data lines
are being studied. The computer program that generates these
charts and tables preferentially draws line peaks at longitudes where
large numbers of earthquakes occurred in the past.
Data Tables such as the ones below for Individual EM
Signals such as the one on the above chart can be helpful for determining
exactly where a chart line peak might be pointing. At times the
longitudes of the chart line peaks might be off a bit from the longitude of the expected
earthquake.
THE HIGH INTENSITY EM 8 EM SIGNAL TABLE DATA
The first horizontal group of tables below are for that high intensity EM Signal.
Table 1 in the above 9 horizontal groups of tables provides a quick summary of how many earthquakes occurred in the
past at around 73 W longitude where the Haiti earthquake
occurred. The matching 73 W entries are highlighted in bold text.
Ordinarily there might be
three to five 73 W area longitude entries in that table. But there
are 19 of them if ones for the earthquake itself are not counted.
That unusually large number of
earthquake longitude entries in Table 1 was likely an accurate and
timely indicator that the Haiti earthquake was approaching.
Additionally, the following earthquake is the second best match for that
EM 8 Signal with past deadly earthquakes. That match was
selected from the 800 or so deadly ones that are listed in the earthquake
database file being used by the computer program that generates these
charts and tables.
1994/03/02 03:38:03 20N 73W 59 5.4
That is almost an exact match for
the latitude and longitude where the Haiti earthquake occurred.
The depth and magnitude are quite different for the two earthquakes.
2010/01/12 21:53:10 18N 73W 13 7.0
Finally, the Haiti earthquake
itself is listed as a high quality match for the EM 8 Signal in all of
the tables where it could appear except for the 5 and higher magnitude
table - Table 9. That is another indicator that the
computer program was able to accurately match the earthquake and the EM
Signal. The Haiti earthquake itself could not appear in the 7.5 and 8.0 and
higher magnitude tables because its magnitude was only 7.0.
THE HAITI EARTHQUAKE TABLE DATA
The group of tables below are for that destructive Haiti earthquake.
The large number of 73 W
longitude entries in Table 1 for the earthquake show that the computer
program was able to find an
unusually large number of matches between that earthquake and past
earthquakes that occurred around that longitude. That indicates
that the earthquake was likely triggered by sun and moon gravity-related
forces that were similar to the forces that triggered earthquakes in
the past in that area.
The earthquake itself also appears
in all of the tables where it could be present. Table 2 shows that
it was the second best match for itself when compared with the 800 or
so deadly earthquakes in the database file. That means that
the computer program equations were do a good job with matching the
earthquake with
itself.
As the Table Data for those 800 or so earthquakes on the Significant-Earthquakes.html Web page show, that is usually, but not always, the case.
The fact that the earthquake was a good match with itself is an
indicator that it is likely that at least some of the EM Signals generated before the
earthquake occurred would accurately point to the correct location for
the earthquake.
