PURPOSE
The purpose of this document is to show that what is reported at the
Earthquake List for Map Centered at 44°N, 110°W (1)
– a hot spot in the Yellowstone caldera area - does not match
what
the seismographs of the area are showing.
Although the list is for "Map Centered at 44°N, 110°W",
that list includes earthquakes that take
place at 109°W as well as the ones that take
place at 111°W. The sector
covered by this map
corresponds to the Yellowstone Region. The earthquake stations used for
this document, which register the Yellowstone portions localized
at 44°N, 110°W are those identified as "Yellowstone Regions" in
the University of Utah
Seismographs as YMV, YSB, YHH, YHB, YMC, YHH, YMR, YUF, YJC, YMP, YPK,
YML, LKW, YLA, YLT, YFT, YTP, YPP and MCID. (2)

INTRODUCTION
To facilitate the
comparative analysis, we will work
with the events that are reflected in several of the stations that
cover Yellowstone's Region. After identifying those which are not
publicly reported on the appropriate pages (but which appear on the
seismograms) we have calculated and report their magnitude as computed
using the Bolt method. (5)
It is not our intention to do an inventory of every event that was not reported as it should have been. To fulfill the purpose of this document it suffices to: (a) select 11 days of non-reported events to be used as sample / test; (b) then select 9 days of reported events and compare the reported magnitude with the magnitude that results from the Bolt method. The period under evaluation comprises from June 2, 2011 to June 25, 2011.

* Those events are located on the seismograms that correspond to
the local date at UTC hour. For example, the event recorded on
seismogram of June 8, 2011 at 1:22:01 UTC, occurred at local time
7:22:01 PM (MDT) and was reported by USGS as occurring on June 9, 2011
at 1:22:01 UTC (Attachments 16-a, 16-b and 16-c).
CONCLUSIONS by The M+G+R Foundation
Obviously that may have been true in 2002
but, as the ample data presented in this Study shows: the only
information that one can be sure of - at least right now - is the raw
readings of the seismographs since in the official pages appear only
what "The Masters" wish to be known by those who visit those pages.
