Those quakes are too deep to come from magma chamber, its just earth's crust. These quakes are pretty much normal and are not sign of magma moving,
just sign that there is some tensions in crust.
But if quakes start to happen at 10km, that is coming from magma chamber. Magma chamber there is 16km thick, 50km wide and 160km long. If quakes start
happening there, its time to run, specially if they happen at top of that chamber. Quakes leading to eruption are not very strong, but they have
harmonic movement, like in waves. Intensity grows, then subsides then again grows in precise intervals.
