As we are at the bottom of the very weak solar cycle number 24, the sun is dominated by very large coronal holes. The magnetic field lines of coronal holes are open, thus they are the sites of fast solar winds as protons and electrons can easily escape into space. Central Italy was struck by several earthquake starting 26 of October 2016 and ending 3 November. The largest was of magnitude 6.5 on October 30. A wide coronal hole in the solar northern solar hemisphere started facing the earth on October 26, enabling fast solar wind streams to strike the earth. Ground electric currents were recorded as a consequence of this coronal hole. The 2016 Kaikoura earthquake was a magnitude 7.8 (Mw) earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016. This earthquake can be attributed to another solar coronal hole located in the Solar Southern hemisphere. The mechanism of initiation of earthquakes due to solar streams is suggested as due to induced electric currents in the ground and magma below the surface that cause movements in the plates of the earth thus induce earthquakes.
