Cwmllynfell y cylch o dân! Yep. No doubt. Bûm yn byw yng Nghymru am nifer o flynyddoedd ar Ynys Môn yn Llanfaelog yn agos at Rhosneigr. Pobl gyfeillgar.

Big paper out by NASA and others NASA are really coming on board with the sun and other global precursors to earthquakes. There paper through references to other papers are a game changer. many of these papers and similar have been ridiculed over the years. www.scirp.org/journal/PaperInformation.aspx?paperID=82421#ref336. Conclusions The Kp index for the times of earthquakes between 1932-2016 was statistically analyzed. Stacking of thousands of Kp data shows an effect of the geomagnetic field on earthquakes triggering. As described in Analysis Summary, a distinct pattern of the Kp fluctuations prior to earthquakes was found, indicating the synchronization of geomagnetic surges and seismicity. These synchronizations are quite complex, reflecting the regional characteristics and the earthquake magnitude itself. M8 class earthquakes are associated with the Kp surge more than M6 class ones. The geomagnetic disturbance, typically the magnetic storm, is one of the major factors which synchronize with earthquakes. This study offers a scientific support to the past numerous researches by the predecessors and the current researchers. 5. Review of Historical StudiesAristotle, the Greek philosopher, described that earthquakes occur more frequently during the night than during the day [4] . Starting at the beginning of the 20th century, studies were performed to determine whether the time sequences of earthquakes follow any systematic pattern. After many studies it became evident that the seismicity exhibits distinct diurnal as well as seasonal cycles in many different earthquake zones [5] - [13] .Such cycles of seismic activity can only be attributed to solar influence. Consequently, studies were done to model such solar-terrestrial effects. The powerful electric current vortices in the ionosphere, generated by solar radiation, and the associated magnetic field variations are assumed to be the essential source for the effect. Due to the penetration of those magnetic field variations into the electrically conductive Earth’s lithosphere, and associated electric “telluric” currents, additional mechanical forces are generated in seismic rupture zones [14] [15] [16] . Another observation that supports the theory of solar influence is the clustering of earthquakes in 11-year cycles in accordance with the solar cycles [17] - [23] .In this overall context, several recent studies focused on the cycles of the solar polar magnetic field, which manifest themselves in solar flare activity. A high degree of statistical significance was shown for a correlation of those polar field oscillations and the occurrence of strong earthquakes [24] [25] . Similarly, it has been stated that, during the Maunder solar minima, the strongest earthquakes and most violent volcanic eruptions took place during transition phases of the heliospheric magnetic field [26] .Other studies deal with the question of whether geomagnetic storms play a role in the triggering of earthquakes. These magnetic storms are generated by a sudden surge in the intensities of the solar wind (plasma) streams, which originate on the sun’s surface and travel with high speed toward our planet. Disturbances of the geomagnetic field caused by this solar influence are classified by the so-called 3-hour Kp Index [27] . Several papers confirm this Kp index to be an appropriate indicator for the solar influence, including magnetic storms, on seismicity [28] [29] [30] [31] [32] .However, another investigation claims to have demonstrated no statistical significance for any solar-terrestrial triggering of earthquakes [33] .

Great FIND!

Could the Solar and Earth effects have a common cause? I wonder if anyone has looked for Length of Day changes and seismicity? (No I didn't mention it ;-) )

No-where near as large as the Mt Pinatubo eruption in 1991, fortunately. So far!!
