Update on activity Eruption in Eyjafjallajökull, Iceland Current events
Deflation - 20 April 2010 13:30 Latest available results from GPS stations around Eyjafjallajökull showed deflation associated with the eruption. This suggested that the volume of eruptive material which has been ejected already, relieves pressure off the volcano. No movements associated with the Katla volcano are presently observed.
Sound blasts - 20 April 2010 12:30 Heavy sound blasts have been heard and found near Eyjafjallajökull, especially south and east of the mountain, and more clearly after wind speeds became lower. The viscosity of the magma from Eyjafjallajökull is higher than on Fimmvörðuháls. This enhances the explosive sound effect. Shock- and soundwaves are carried long distances.
Large igneous provinces (LIP) such as Iceland, the Siberian Traps, Deccan Traps, and the Ontong Java Plateau are extensive regions of basalts on a continental scale resulting from flood basalt eruptions. When created, these regions often occupy several thousand square kilometres and have volumes on the order of millions of cubic kilometres. In most cases, the lavas are normally laid down over several million years. They do release massive amounts of gases. The Réunion hotspot produced the Deccan Traps about 65 million years ago. Research continues into the effect of the outpourings and whether they contributed to the extinction of the dinosaurs at the end of the Cretaceous.
Such outpourings are not explosive though fire fountains may occur. Many volcanologists consider that Iceland may be a LIP that is currently being formed. The last major outpouring occurred in 1783–84 from the Laki fissure which is ~40 km long. An estimated 14 km3 of basaltic lava was poured out during the eruption.
What I see is a small bump or spike if you will,.. What will be of significance to this reading?

I would like to draw your attention to This . Now while we can go back and forth on causing alarm, we, have a situation here that can go anywhere. As such, knowledge and understanding is the Key! Knowledge and understanding can keep you alive and safe. Be knowledgeable Folks, Be prepared for anything and hope for nothing. I do not want to scare people - I just want to keep you abreast of the situation at hand. So you all are not caught off guard and are prepared. Better to be safe and prepared always for anything.
..and with human technology, not enough to stop us.
