Recurrent coronal hole sparks another round of geomagnetic storming
Posted by TW on September 27, 2016 in category Geomagnetic storms
High-speed solar wind from a recurrent coronal hole has sparked another round of geomagnetic storming on Earth. The solar wind environment is expected to remain elevated but steady through the rest of the UTC day before becoming further enhanced on September 28 and 29. This feature produced G2 geomagnetic storming during its last rotation through the Earth side of the Sun and similar conditions are expected during this one too.
G1 Minor geomagnetic storm threshold was reached at 01:19 UTC on September 27, 2016.
Multiple Earthquakes Rattle Imperial and San Diego Counties
By R. Stickney and Samantha Tatro
Twenty four small earthquakes, the strongest of which was a magnitude 4.3 quake, rattled Imperial County starting early Monday and continuing on into Monday evening.
The first quake, measured at a magnitude of 4.2, struck at 7:31 a.m. PT.

Solar activity, as indicated by sunspots, radio noise and geomagnetic indices, plays a significant but by no means exclusive role in the triggering of earthquakes. Maximum quake frequency occurs at times of moderately high and fluctuating solar activity. Terrestrial solar flare effects which are the actual coupling mechanisms which trigger quakes appear to be either abrupt accelerations in the earth's angular velocity or surges of telluric currents in the earth's crust. The graphs presented in this paper permit probabilistic forecasting of earthquakes, and when used in conjunction with local indicators may provide a significant tool for specific earthquake prediction.

This paper inspects possible influence of solar cycles on earthquakes through of statistica lanalyses. We also discussed the mechanism that would drive the occurrence of increasing of earthquakes during solar maxima. The study was based on worldwide earthquakes events during approximately four hundred years (1600-2010).The increase of earthquakes events fol-lowed the Maxima of Solar cycle, and also de-pends on the tectonic plate location. From 1600until 1645 events increased during the Maxima in some of the tectonic plates as Pacific, Ara-bian and South America. The earthquakes ana-lyzed during two grand solar minima, the Maunder (1645-1720) and the Dalton (1790-1820)showed a decrease in the number of earth-quakes and the solar activity. It was observed during these minima a significant number of events at specific geological features. After the last minima (Dalton) the earthquakes pattern increased with solar maxima. The calculations showed that events increasing during solar maxima most in the Pacific, South America or Arabian until 1900. Since there were few records during these three centuries we needed addi-tional analysis on modern data. We took the lastfour solar cycles events (1950-2010) and madesimilar calculations. The results agreed with the former calculations. It might be that the mecha-nism for the Sun-Earth connection relies on the solar wind speed. In both records (1600-1900)and (1950-2010) the results showed a significant increase in earthquakes events in some of the tectonic plates linked to solar maxima. The So-lar wind energy striking the Earth’s magneto-sphere affects the entire environment because the pressure on the region increases and the magnetosphere shrinks sometimes four Earth’sradii. This sudden compression causes earth-quakes in specific plates.

The historical record of large volcanic eruptions from 1500 to 1980, as contained in two recent catalogs, is subjected to detailed time series analysis. Two weak, but probably statistically significant, periodicities of ~11 and ~80 years are detected. Both cycles appear to correlate with well-known cycles of solar activity; the phasing is such that the frequency of volcanic eruptions increases (decreases) slightly around the times of solar minimum (maximum). The weak quasi-biennial solar cycle is not obviously seen in the eruption data, nor are the two slow lunar tidal cycles of 8.85 and 18.6 years. Time series analysis of the volcanogenic acidities in a deep ice core from Greenland, covering the years 553-1972, reveals several very long periods ranging from ~80 to ~350 years and are similar to the very slow solar cycles previously detected in auroral and carbon 14 records. Solar flares are believed to cause changes in atmospheric circulation patterns that abruptly alter the earth's spin. The resulting jolt probably triggers small earthquakes which may temporarily relieve some of the stress in volcanic magma chambers, thereby weakening, postponing, or even aborting imminent large eruptions. In addition, decreased atmospheric precipitation around the years of solar maximum may cause a relative deficit of phreatomagmatic eruptions at those times.

I also recall you claiming that solar activity cannot affect earthquake activity even thou actual scientists and their research papers disagree with your view, among other claims you have made.
Do you forget as well that the strength of Earth's magnetic field in that area would also affect whether these solar events can trigger earthquakes or not? Or which areas are hit the most by these geomagnetic storms?

Sometimes when I step into my shower the phone rings.
Do you want me to find earthquake "flurries" which are not correlated to geomagnetic activity? Or G2 storming without "flurries?"
G2 is storming pretty mild, btw.

Abstract Results of studying the character and possible succession of cause-effect relations (in going from a disturbance source on the Sun to a response in the lithosphere in the range of periods from several days to the 11-year solar cycle) have been presented. It has been indicated that the maximum of seismic energy, released from earthquake sources in the 11-yr cycle of sunspots, is observed during the phase of cycle decline and lags 2 yr behind the solar cycle maximum. It has been established that the maximum in the number of earthquakes directly correlates with the instant of a sudden increase in the solar wind velocity.

Abstract The relationship between the length of the solar cycle, a good indicator of long-term change in solar activity, and natural disasters (drought, flood, and strong earthquakes) in China during the last 108 years is analyzed. The results suggest that the length of solar cycle may be a useful indicator for drought/flood and strong earthquakes. When the solar activity strengthens, we see the length of the solar cycle shorten and more floods occur in South China and frequent strong earthquakes happen in the Tibetan Plateau, but the droughts in East China as well as the strong earthquakes in Taiwan and at the western boundary of China are very few. The opposite frequencies occur when the solar activity weakens. The current study indicates that the solar activity may play an important role in the climate extremes and behavior in the lithosphere.

Abstract. The experimental data on high-energy charged
particle fluxes, obtained in various near-Earth space experiments
(MIR orbital station, METEOR-3, GAMMA and
SAMPEX satellites) were processed and analyzed with the
goal to search for particle bursts. Particle bursts have been selected
in every experiment considered. It was shown that the
significant part of high-energy charged particle bursts correlates with seismic activity. Moreover, the particle bursts are observed several hours before strong earthquakes; L-shells of particle bursts and corresponding earthquakes are practically the same. Some features of a seismo-magnetosphere connection model, based on the interaction of electromagnetic emission of seismic origin and radiation belt particles, were considered.
