Measurements of the flux of Sulphur dioxide gases from the volcano also show a slow baseline increase with time. Superimposed on this trend are many pulsations. A major shift in the volcano's behaviour occurred around 20 July 1996 which heralded an escalation of activity in the following months. The recent volcanic activity in south Iceland, that began late evening on March 20, 2010, had been preceded for some weeks by intense seismic activity and deformation ().Lava flowed from a fissure on the ice-free flank of the Eyjafjallajkull volcano, but ashfall from its 1-km high plume was insignificant. 12 May 96 "Mothers Day" pyroclastic flows reached the sea for the first time.
