There is a correlation between the solar minimum cycle and increased volcanic activity on Earth. The next solar minimum cycle 2019-2020 is forecast to be especially minimal. I can't find the link right now but a Japanese study linked the cycle specific to high-silica magma (Hawaii volcanoes are low silica) but I think that was because they were studying Japanese volcanoes. The Japanese study also linked the cause to be that during the solar minimum the Earth is less protected by the sun's magnetic field and that cosmic rays somehow interact with the magma. I think the NASA study blames a change of the Earth's rotation. Whatever the cause, the link between terrestrial volcanic activity and Sun activity have been linked in multiple studies and we are entering a period of reduced sun activity and therefore increased volcanic activities.
I didn't fact-check it but I had read that the next solar cycle is supposedly the weakest since the Maunder Minimum ( https://en.wikipedia.org/wiki/Maunder_Minimum ) which supposedly caused "the little ice age". I think I remember reading that there were ~17 major volcanic eruptions during that time frame.
