Toward the end of the article they say "don't worry" and then post this explanation !
"Long-period (LP) or low-frequency (LF) earthquakes are caused by cracks resonating as magma and gases move toward the surface. They are often seen prior to volcanic eruptions, but their occurrence is also part of the normal background seismicity at some volcanoes and their occurrence does not necessarily indicate that an eruption is imminent. LF events can also be produced by non-magmatic processes, most notably glacier movement.'
i didn't know there was a glacier under Kilauea !!
