Mount etna might be about to pop as well. This could seriously mess up summers for several years, like Mt St Helens did.
A series of earthquakes occurred on April 2-3 along a fault near the north flank of the volcano - 175 earthquakes in all producing some impressive results - and scientists have noted increased "rumblings" at Etna since. This has culminated in explosions and ash April 7-8.
Most of the ash appears to be made from merely crushed rock of previous eruption - accidental material rather than new juvenile magma, but all of this suggests that Etna could be headed for a new eruptive period.
There has also been an increase in the gas emissions from the volcano - all signs that new magma may be rising in the conduit and a new eruption is approaching.
