A new study on the correlation of
mega earthquakes and sunspot activity
is soon to be released
by a team out of Kyushu University, Japan.
October 1st, 2011
A friend just pointed us to this article, “Mega Quakes Occur More Frequently When the Sun has Fewer Sunspots,” discussing a study soon to be released by a team out of Kyushu University, Japan. The article states,
Sunspots gradually increase and decrease in number in a cycle of about 11 years, and cause changes in the earth’s atmosphere. The research team investigated the possibility that they could also produce changes beneath the earth’s surface, and compared data on the number of sunspots between 1963 and 2000 and the 327,625 earthquakes of magnitude 4 or more that occurred during this period.
The study found that 65 percent of the earthquakes with magnitudes between 4.0 and 4.9 occurred during the periods with the fewest sunspots (each lasting about two years). The figure was around the same for earthquakes with magnitudes between 5.0 and 7.9. However, the figure was higher for the 28 mega earthquakes with magnitudes in the 8.0-9.9 range, with 79 percent of them occurring during periods with the fewest sunspots.
When there are fewer sunspots, a phenomenon occurs in which solar winds, or streams of charged particles from the sun, get stronger an average of three to four times a month. Seventy percent of the earthquakes of magnitude 6.0 or stronger occurred at such times.
I’ll be looking forward to getting my hands on the details of the study. Since the March 11th, 2011 quake that tragically hit Japan we’ve taken up an increased focus on the threat of earthquakes, including the role of solar and galactic interactions, and the ability to forecast earthquakes and defend humanity from these threats.
This started with Peter’s production, The Rim of Fire.
Following this we featured an interview with Professor Sergey Pulinets on the science of earthquake precursors, and the ability to forecast earthquakes, Sergey Pulinets: A Multi-Parameter Approach to Earthquake Forecasting. Then Oyang pulled together an excellent short presentation on the precursors before the March Japan quake, Japan Quake Precursors.
Peter also wrote a great article on the necessity for a new approach to geophysics, The Importance of NAWAPA for Geophysical Research.
This work is consolidated on our Mastering the Forces of Nature page, which includes our own custom global earthquake monitor.
This new study on the correlation of mega earthquakes with low sunspot activity could be quite interesting. We will certainly have more as it comes out. The article says that the results will be announced at a meeting of the Society of Geomagnitism and Earth, Planetary and Space Sciences, which opens in Kobe, Japan, on Nov. 3.
