"The newest set of quakes are all focussed under areas of the glacier with approximately 100-200 metres thickness of ice. Depending upon which side of the north-south Eyjafjallajkull drainage gradient an eventual new fissure might poke through, the resulting water pool and heated steam under the jkull will exert upward pressure and ultimately burst out either under the Steinsholtsjkull glacial tongue to the north (draining into the narrow upper valley of the Kross and down into the Markarfljt sandur) or will stream down a narrow gorge to the east of the (south) Godasteinn peak on Eyjafjallajkull, as indicated in the inset illustration -- within the Meteo article above." "Their additional concerns, at this late winter season, are about massive ice and snow slides from the steeper southern side (slope failures similar to avalanches) triggered by the undermining of high volumes of heated water flowing downhill in this direction... and are primarily motivated by the short warning times involved. Such slides will sweep over the highway now being used by many tourists coming to the volcano, in addition to regular circumferential traffic on Highway 1." I feel that the continued concentration of magma's upward pressure -- albeit unsuccessful -- is to break through whatever obstacles have been retarding its progress down there at the 6 km. or so level. Nonetheless magma has continued to get within .2 kilometres of the surface on three occasions in the past 48 hours during multi-quake sequences... and all those quakes have been in very close
