No conspiracy - just simple geology and physics. The ocean floor is pretty thin where you get these hot spots. Based on the convection currents in the molten rock and lighter densities, they can move pretty rapidly.
Think about the seismic detection of the magma movements (recorded as "microquakes" under the volcano) at Mount St. Helens and how soon after we got the big eruption. This was a much denser felsic lava and much slower moving than the basaltic lavas you would see erupting in the Hawaiian Islands, Surtsey or any of the oceanic volcanic provinces.
