“…On the other hand, our conclusion is different from that reached by Odintsov et al . [, Figure 2], who identified a seemingly significant difference between the average number of earthquakes ( M ≥ 7.0, 1900–1999) occurring during sunspot maximum and minimum years (Student's t test, p < 0.05). In response to the analysis of Odintsov et al .…”

“…In response to the analysis of Odintsov et al . [], we conducted a Student's t test like theirs. We find that the difference between the average number of earthquakes during sunspot maximum and minimum years is insignificant ( M ≥ 7.5, 1900–2012, p = 0.88).…”

“…For example, over long time scales, global seismicity has been reported to be highest during solar‐cycle sunspot maximum [e.g., Odintsov et al ., ] and, very differently, highest during the declining phase and minimum of the solar cycle [e.g., Simpson , ; Huzaimy and Yumoto , ]. Over shorter time scales, global seismicity has been reported to be correlated with solar‐quiet geomagnetic variation [e.g., Duma and Ruzhin , ; Rabeh et al ., ], with geomagnetic disturbance [e.g., Simpson , ], and with enhanced solar wind velocity [e.g., Odintsov et al ., ]. There have also been reports that regional seismicity is correlated with magnetic‐storm occurrence [e.g., Sobolev et al ., ; Bakhmutov et al ., ].…”

[1] We examine the claim that solar-terrestrial interaction, as measured by sunspots, solar wind velocity, and geomagnetic activity, might play a role in triggering earthquakes. We count the number of earthquakes having magnitudes that exceed chosen thresholds in calendar years, months, and days, and we order these counts by the corresponding rank of annual, monthly, and daily averages of the solar-terrestrial variables. We measure the statistical significance of the difference between the earthquake-number distributions below and above the median of the solar-terrestrial averages by w 2 and Student's t tests. Across a range of earthquake magnitude thresholds, we find no consistent and statistically significant distributional differences. We also introduce time lags between the solar-terrestrial variables and the number of earthquakes, but again no statistically significant distributional difference is found. We cannot reject the null hypothesis of no solar-terrestrial triggering of earthquakes.

The relationships between solar activities (sunspots, solar 10.7cm radio flux, solar irradiance, and solar proton events) and local earthquakes investigated in this paper. The geographical location of study is New Zealand area. All earthquakes data have been chosen for ≥ 4, from first of 1970 to Jun 2012. The study reveals the following conclusions: 1) The total numbers of earthquakes strongly show annually an increasing in number of earthquakes in New Zealand from 42 years ago.2) The maximum earthquakes occur frequently around the minimum years of solar activities, 3) The maximum earthquakes occurs in minimum years of sunspots number with a good correlation coefficient. 4) The maximum earthquakes occur in the minimum solar 10.7 cm radio flux with strong correlation coefficient.
