    Entretanto tem estado mais calmo, o mais provável é não haver erupção:

    Specialist remark
    Earthquake activity is decreasing near Grindavík but around ten earthquakes have been detected in the area since midnight, all below M2.0. Yesterday ( 4. Feb) around 60 small earthquakes were located in the area. Most of them are below M2.0.

    Since the 21st of January over 1300 earthquakes have been located in the area, there of, around 700 over the weekend. Most of them are located in a SW/NE line around 2 km NE of Grindavik.

    The latest GPS processing shows that the uplift west of Þorbjörn is still ongoing. In total the uplift is about 5 cm since the 21st of January. With ongoing uplift we can expect ongoing earthquake activity. The most likely explanation of the uplift and earthquake activity is that we have a magmatic intrusion at 3 to 9 km depth just west of Þorbjörn. It is most likely that this activity will stop without any eruption. The next meeting of the scientific council of Department of Civil Protection and Emergency Management will be next Thursday.
