My problem is understanding what diurnal temperatures have to do with the magma deep underground. Daily temperature variations only go a few meters deep in rocks, which are so small compared to magma's temperature. A few degrees of temperature change are insignificant compared to the magma, and the recent eruptions are not correlated with atmospheric temperature. So, your hypothesis doesn't seem to stand up to initial scrutiny, even though I don't know what it is. If there's something I missed, let me know.
