In english and non scientific translation:just you wait until the lahars and pyroclastic flows start, immediatly after comes the eruption.
The eruption generally comes directly after that long drawn out 'wet' sounding ass ripper of a fart, the morning directly after la' vindalooooooooo.
Tremors are then usually heard for the next few minutes directly afterwards with the occasional 'last blast' as the volcano sheds its final spurts of 'lava'.
Reports of vibrations caused by said effects are reported as far back as the kitchen, down the stairs and at the back of the house
Fortunatley no-one is harmed during this earth moving event but the clear up operation could take a while as the effects are only too obvious.
(seriously took that to far lol)

Just spoke to my next door neighbour and they felt the earthquake last night where I missed it
