Over the past weeks there have been deep earthquakes happening under Eyjafjallajökull. The deepest earthquake so far that has happened was on 21 km depth. The latest earthquake that happened was on close to 15 km depth. Currently it is impossible to know if there is new magma pushing up.
If it is, then the amount of magma that is rising up trough Eyjafjallajökull is not great and is unlikely to start a new eruption any time soon. It is however worth noticing that this might change with a short notice. But the eruption in March to May 2010 did show that magma can rise fast up trough Eyjafjallajökull and appears to be followed by earthquake activity.
