Click to Enlarge: The green squares denote the Hyper-Days of the Tzolkin cycle. The study period starts with day 41 and ends on day 223 of the Tzolkin cycle. The former Tzolkin date corresponds to Sept. 1, 2009 and the latter with Mar. 2 2010. The two consecutive stretches of green squares on either side of the central column are known as Hyper-Day Sequences. This information will be useful when you encounter the plots.

Tzolkin Cycle and Hyper-Day Brief

The days key to this study are known as Hyper-Days and there are 52 such days within the overall 260 day Tzolkin cycle. Please see the Tzolkin chart image and caption to your left for an orientation to the Hyper-Day order. The chart is read from top to bottom starting with the square in the upper left corner containing  the number 1, meaning day 1 of the Tzolkin cycle.

The 52 Hyper-Days of the Tzolkin stand out from the all other Tzolkin Cycle days by possessing a characteristic that corresponds with the intensification and amplification of all terrestrial phenomena inclusive of the human domain, hence the term Hyper-Day (HD) to denote hyper-activity.

My study of Tzolkin Cycle has led me to note how activity of all sorts seems to “start up”, “ramp up”, and “boil over” with the onset of a Hyper-Day.

Peak events and tipping points are also apt descriptors of the events that have a propensity to occur during what I call a Hyper-Day Window (HDW).

A HDW is the day before, the day of, and the day after a HD.

I provide some links in the next paragraphs that cover the range of activity that pertain to Hyper-Days.

An Unexplained Phenomena
The Tzolkin chart to your left only maps the 260 days of the cycle in codigraphic form, it does not explain the basis or origin of the cycle.  For an introductory brief on the Tzolkin cycle please consider reviewing the orientation on Tzolkin Cosmology.

After reviewing this study you may want to review another study entitled “Empirical Evidence for the correlation between Tzolkin Cycle Hyper-Days and Earthquake Frequency-Intensity Spikes over a 6.25 month period”.


Study Procedure and Methods
I obtained all of my data for this study from the Global Volcanism Program, a joint effort of the Smithsonian Institution and the US Geological Survey. I began by recording the number of volcanic events according to the day on which they occurred.

The study period starts September 1, 2009, and ends March 2, 2010.

The data was placed in two categories. The SI-USGS Global Volcanism project lists volcanic activity under the categories of either New Activity/Unrest or Ongoing Activity. Those interested in the specific criteria regarding activity classification may visit the link.

The Tzolkin date converter used for this study is found here.

What is a Volcanic Event?

Under the category of New Activity, I noted the following types of events named in the data resource:

  • Lava Fountains
  • Dome Collapses
  • Effusions of Lava
  • Thermal Anomalies
  • Explosions/Eruptions
  • Increased Seismicity (quakes)
  • Emission of Gas, Steam, and Ash
  • Ejection of Hardened Lava blocks
  • “Roaring, Booming, or Rumbling Sounds”

Under the category of Ongoing Activity I noted

  • Lava Fountains
  • Dome Collapses
  • Effusions of Lava
  • Explosions/Eruptions
  • Emission of gas, steam, and ash.
  • Ejection of hardened Lava blocks

I did not list seismic tremors, thermal anomalies, or sounds for the Ongoing Activity category, nor did I list the activity for the non-stop Kilauea volcano of Hawaii.

If any one of the above events took place on a specified date I assigned a value of one to each kind of event, and plotted the sum number of events on the day(s) specified to have occurred by the SI-USGS global volcanic activity reports.

If multiple events of the same kind, say explosions, happened on the same day for a given volcano, I did NOT count each individual event, but rather I assigned a value for the occurrence of “types of events” per given day.



My working hypothesis is based on my multi-year study of the Tzolkin cycle. My understanding and observations of the Tzolkin cycle  led me to hypothesize that the hyper-activity I noted on Hyper-Days should be reflected in volcanism and  earthquake activity if my understanding of the Tzolkin cycle is correct.

Therefore, I am looking for evidence of greater activity in terms of volcanic event frequency (quantity) and intensity in my studies. The study on earthquakes measured both aspects. This study on volcanoes measures only the frequency, or number of volcanic events per day.

Volcanic activity is constant, but like everything else it fluctuates. The question is; might some of the fluctuations in activity be attributable to the Tzolkin cycle?

Research Highlights

Research findings suggest that volcanic activity (VA) is, by a large measure, greatest during Hyper-Day Windows HDW’s.

  • 26 of the top 32 days registering VA greater than 8 events concurred with a HDW. In other words, 81% of days with the highest scores of VA were HDW’s
  • 31 of the 44 peak event days* of Total Volcanic Activity (TVA) of any magnitude concurred with a HDW, or said another way, 71% of all peak event days of TVA concurred with a HDW.
  • 32 of the 44 peak event days in New Volcanic Activity (NVA) of any magnitude concurred with a HDW, or 73% of all peak event days of NVA concurred with a HDW.
  • 3 of 3 other measures exemplified in the following Bar Graphs also indicate that VA is greatest during HDW’s. The 3 measures are:
  • Average Daily Volcanic Activity
  • Volcanic Event Frequency
  • Volcanic Event Surge Intensity

* A peak event day is characterized by an increase trend that stops and decreases the very next day. On the plot graphs they are denoted by the sharp green triangles.

Six of the 6 key measurements all indicate that volcanic activity is by far the greatest during HDW’s

Data Measures: The Graphs
The first graph I present plots volcanic activity between September 1, and October 29, 2009.

You will find two other plots like the Sept-Oct one for Nov-Dec 2009 and Jan-Mar-2nd 2010 at the end of this article.

Bar graphs bearing out the mathematical results start immediately after plot number one. On the plots themselves I note other telling features in text boxes. Click on the Images to Enlarge.

Important Note: The study spanned a period of 181 days. 91 days correspond to HDWs and 90 days correspond to Standards Days.

Neither type of day has a quantitative advantage worth factoring for given the very large margins that the concurrence of volcanic activity shares with HDW’s in contrast to Standard Days. This aspect of the study makes the results even more salient in favor of my hypothesis.

The data provided by the plot graphs enabled me to create the following bar graphs.  There are 2 more plot graphs below.

Bar Graph 1:

Contrasting the Event Frequency of New Volcanic Activity between HDW’s and Standard Days

The measure of bar graphs 1 and 2 was established by categorizing every day of the study period according to the number of new volcanic events reported for a specified day by the SI-USGS Global Volcanism report. I then contrasted the number  of events with the type of day they fell on. There are 2 “kinds” of days in this study, there are hyper-days and there are standard days.

Study volcanism bar graph 1

I’ve noted the propensity of systems near the brink of a phase transition to be pushed over the edge to the new state during a HDW. In the case of volcanic activity, we are talking about a volcano that goes from a state of rest or inactivity to a state of activity. This study supports that observation as new volcanic activity was more prone to occur on a HDW’s by large margins.

On days registering 2 or more volcanic events, 42 of 59 events concurred with a HDW. That is very significant when the measurement scale ranges from 1 to 6 events per day. New Volcanic Activity was much greater on HDW’s in 5 out of 6 categories, whereas Ongoing Volcanic Activity was greater on HDWs in 6 out of 12 categories.

In each case, the greater the magnitude of activity, the greater the chances it concurred with a HDW versus a standard day. All 4 bar graphs bear out what I have just indicated. HDW’s are associated with marked increases in all types of volcanic activity, be it a waking volcano, or the increased activity of an “awakened one”.

Bar Graph 3:

Contrasting the Surge Intensity of New Volcanic Activity between HDW’s and Standard Days

By “surge intensity” I mean the difference in the number of volcanic events from one day to the next. The aspect measured by bar graphs 3 and 4 was established by categorizing the upticks in the number of volcanic events according to the difference in the number of events from one day to the next.

If on one day there were 3 volcanic events, and then the very next day there were 6, then the “magnitude of surge intensity” was a value of 3. I then recorded the number of times the various surge categories happened during the study.

New Volcanic Activity recorded the greatest number of surge events during HDW’s in 4 out of 5 surge categories. Whereas the graph measuring the same for Total Volcanic Activity recorded the greatest number of surges events in three of eight categories relative to Standard Days. But those three categories where the 3 most extreme surge categories. Each measurement thus far offers strong support for the statement that volcanic activity is greatest during HDW’s.

Contrasting the Averages of New and Total Daily Volcanic Activity between HDW’s and Standard Days,
Bar graph 5 charts the daily averages of New and Total Volcanic Activity according to the three bi-monthly plot graphs used in this study.

Averages are not the most revealing of statistics, as they unnaturally flatten the natural ups and down of all phenomena, and cyclical behavior is what I am attempting to discover. Nevertheless, I have provided averages of daily volcanic activity, and then contrasted HDW and Standard Day averages.

Here too we find that the average number of Volcanic events is greater on HDW’s in the Total and New Volcanic Activity categories. There was only one study period (Sept-Oct) where the average was slightly higher for standard days. However, the average for the entire 6 month study period in New and Total VA categories supports the statement that most volcanic activity takes place during HDW’s

Hyper-Day Sequences:

Plot graph 2 displays a distribution of HD’s much different from the other 2 plots, in that the months of November and December 2009 coincided with the two unique stretches of ten consecutive HD’s (Hyper-Day Sequence) that are found on either side of middle column of the Tzolkin Cycle chart.

Please see the Tzolkin chart shown near top of page for orientation. As with HD’s, I include the day before and after the Hyper-Day Sequence (HDS) as part of the total HDS count.Volcanic Activity Plot Nov-Dec

Iceland Volcano Eruption Update: This study was published on March 19th, 2010, and it coincided with the first day of a 3 day Hyper-Day Window.

The Iceland volcano erupted on March 20, 2010, and that date corresponds with Tzolkin date 241. Tzolkin date 241 is the 51st Hyper-Day of the 260 day Tzolkin Cycle.
